Continuing lymphedema treatment

At the conclusion of July’s post, Carol was waiting for her hose.  They arrived & she loved them! One problem: The manufacturer didn’t sew the ankle pocket around the full ankle as requested. Turns out, this manufacturer couldn’t sew a pocket all the way around the ankle. Why didn’t they mention that before? Without the pocket, the hose would slip down & bunch, causing pain.

Long story short, I complained, sending copies of communications with the manufacturer’s customs department describing the need for a full pocket and why. Their response was fantastic. They gave us a refund due to the situation.  Carol and I tried two more manufacturers and finally got what she needed. We’re still working on adjustments, but she’s very happy with the containment and feel of the compression garments.

The compression she likes

The hose were one of several impediments Carol has faced. I mentioned some of them in July. Let’s look at a few more.

Complication – diarrhea

Carol went back to a Keto diet she had used to lose weight in the past (the obesity weight, not the lipedema weight). The diet calls for ingesting a particular oil and liquids the first week which gave her diarrhea. Sometimes that diarrhea ended up on leg bandages. So, she would remove the bandages to shower and her legs would refill. Eventually, she progressed in her diet and recovered from that complication.

Complication – emotional upheaval

Losing someone close to her earlier this year, she has struggled with the void their passing created. In addition, she had a major life change – her job.  Covid caused a lot of people to feel isolated as they worked from home. Carol felt isolated, too. After months of structural change (which included moving people she had worked with for years to other departments), she decided to retire. Now she was not only home and alone much of the time, she also wasn’t interacting with the people she enjoyed talking to. Carol is an extrovert, so this was a hard adjustment. She’s currently pursuing virtual counseling options.

Complication – transient ischemic attack (TIA)

As if the prior complications weren’t enough, she spent a weekend in the hospital after experiencing symptoms of a stroke, including spiked blood pressure and difficulty talking (in this case, the speech difficulty was expressive aphasia). She had just been to see her doctor a few weeks before. She was told her cholesterol was elevated and she was given a new medication to help. Then she awoke one Saturday morning unable to talk.

She was taken to the ER by ambulance. After a day of monitoring, they released her with inconclusive results that pointed to a TIA. A TIA is often referred to as a “mini-stroke.” Symptoms are less severe than a stroke and don’t usually last long because the blockage in the brain is temporary.  In the days that followed, Carol had occasional difficulty pronouncing words and remembering lyrics to some of her favorite songs, but words were coming back to her. Over the next several days, as we worked on her aphasia and as she practiced on her own, speech improved. But not for long.

More recently, she has been complaining of numbness in her face that comes and goes.  I noticed her speech seemed to be getting worse in our last session (even when she slowed down). Her doctor wanted her to hold therapy until she consults a neurologist. That is where we are now. Waiting for her hose revisions and waiting to find out what’s causing her aphasia and numbness.

Conclusion of the lipedema blog series

Carol has had several battles during her lymphedema treatment. But her persistence paid off & she’s made some awesome functional gains as she’s gotten her legs under control. She can get up and down from her chair, in and out of bed, and in and out of her car.  She drove a couple times (which she hasn’t done in a year).  She has more work to do (much of which is on hold pending her neurology follow up), but she’s still motivated — & she’s happy with her lower leg status. I hope to give you a positive update on her condition in the future.

Getting Treatment

Carol started treatment to reduce her leg size. We began with manual lymph drainage (MLD), multi-layer compression bandaging (using a liner, toe gauze, foam, and short-stretch bandages) three days a week. We added exercise and skin care. (This four-part treatment is called Complete Decongestive Therapy or CDT).

toe gauze and two-part leg liner
white foam with application of short-stretch bandage to lower leg

She lost volume quickly – very quickly. In fact, her compression would slip down prior to the next visit allowing refilling. (This was later resolved using an adhesive lotion and an elastic Tubular sleeve.) But progress wasn’t without its complications.

Complication – mobility

Although I recommended Carol start with one leg (bandaging to her groin), she wanted to start with both legs. To avoid returning too much fluid to her heart and kidneys too fast, we bandaged both legs to the knee only the first week of treatment. Bandaging both legs made getting up from her chair more difficult because it limited ankle flexion. Carol later decided she wanted to bandage one leg only. As a result of straining to get up from her chair, she developed biceps tendonitis, causing shoulder pain.

Complication – skin integrity
left leg progress bandaging full leg (including thigh)

Carol also found getting to the bathroom promptly was a challenge (causing her to soil herself and the thigh-high bandages).  Because she hadn’t performed her normal hygiene routine, she developed a yeast infection and skin breakdown under her abdominal fold.

Complication: refilling and weight gain

Unhappy with her hygiene status, Carol began removing her compression to shower before I arrived, allowing her leg to refill. Despite encouragement to continue thigh-high bandaging with hygiene modification (such as using a cast protector to shower), she decided she wanted to regress bandaging to the knee only. As a result, her thigh refilled and she regained some of the weight she had lost. Because of the atypical leg shape, bandaging was tricky & a few times she had heel pain due to pressure. This problem was resolved by fabricating a doughnut foam shape and placing it under her compression, offloading the pressure to her heel.

heel redness (stage I pressure wound) from bandaging and resting bandaged heel on chair
Complication – shoulder pain

Carol’s shoulder pain persisted. We raised the height of her chair by adding pillows, but she couldn’t get comfortable due to hip arthritis pain. I encouraged her to modify her chair height by letting me install 2x4s. She declined feeling this was regression instead of progress. (She felt she just needed to be stronger.) Several sessions later, as her shoulder pain got worse and as she became frustrated having to ask her spouse for help getting up, she agreed to modify her chair. She later described this modification as “life changing.” When she became compliant applying ice to her shoulder to reduce inflammation, and as she continued to use the 2x4s installed for chair height elevation, her shoulder pain went away.

Left: chair frame before modification. Center: using a circular saw to cut 2x4s. Right: chair elevation after modification. The 2x4s were secured using a metal drill bit and carriage bolts (recessed into the wood). The blue duct tape was solely for reinforcement, not structural integrity.

We added exercise to her bandaging, and she slowly began to see more functional progress. She is now able to get into her bed & into her car on the driver’s side without assistance. While therapy has encountered other complications, at this point, we are waiting for her knee high compression hose (and I’m hoping she will later get custom, flat-knit biker shorts (capri length) with a zipper for full leg & abdominal compression). Stay tuned!

The Unthinkable Happened

Then the unthinkable happened.  One day a coworker stopped Carol to say she had something running down the back of her leg & on her pants. In fact, it was on both legs. She had developed wounds and didn’t know it. She went to a wound care clinic who told her something she had never heard:  You have lymphedema. She went to a lymphedema therapist who provided massage and compression bandaging. At the end of treatment, Carol was fit with custom, flat-knit compression hose. However, because of the unusual leg shape common to Lipedema (a condition she wasn’t yet aware of), the hose bunched around her ankle & caused pain. So, the foot of the hose was removed under the manufacturer’s warranty, and she wore compression from her ankle to her knee. At the time, her shoes seemed to provide enough compression for her feet. Her wounds had healed, and she loved her compression.

Ankle cuff causing hose to bunch

She wore her hose until they began to fall apart. Carol needed new compression but her former therapist wasn’t available. Not having any help, she searched the web and found hose she thought would work. But she didn’t know anything about compression sizing, strength, what gradient pressure was – in short, she didn’t have guidance and the compression she bought didn’t work. Her legs got bigger, and she was worried she would end up with wounds again. She began looking online for help and came across me.

Symptoms of lipedema

When I met Carol, I immediately recognized her leg shape as suspect for lipolymphedema (lipedema and lymphedema). Her legs were grossly symmetrical (meaning both legs looked about the same) and her feet were swollen but smaller. She had a definitive cuff around her ankle and while she was likely obese, there was more to her appearance than that. I asked Carol if she had ever been diagnosed with lipedema. She had never heard of the condition. I asked a few questions about her family and medical history.

She was very healthy and had no heart or kidney issues. At some point, though, a doctor had put her on diuretics. The diuretics helped for at time & then seemed to stop working. While she didn’t feel she ever bruised easily, during her evaluation, I noticed a bruise on the back of her leg that she wasn’t aware of (and she denied using a blood thinner).  In fact, she didn’t take any medications other than one for her thyroid.  She also denied feeling hypersensitive but had never really paid attention (her legs were hypersensitive to mild touch during our assessment).  She had knee & hip pain (a common characteristic in lipedema due to stress put on the joints). The arthritis had become so bad, she had to start using a walker. She cried as she told me about the first day she went to work with the device. In Carol’s mind, a walker was something “old people” use. As we talked about her family history, something stood out. At first, she said her mom had always been tiny, but later she mentioned her being diagnosed with elephantiasis (stage III of lymphedema) after the birth of Carol’s sibling. (It’s highly unlikely her mom went from tiny to elephantiasis after childbirth. She likely had swelling for years but, as a child, Carol just hadn’t noticed.) Carol was always hyper-flexible (a trait some people with lipedema have), and she struggled with her weight since adolescence (a time of hormonal change).

Sisters

Carol’s sister happened to be visiting during the evaluation. She told me all of their siblings had leg swelling and used compression now, but no one had as much swelling as Carol. Not only was she physically declining, but she was worried about her sister’s emotional & psychological health. Carol was a people-person but since Covid, she had been confined to her home. She became depressed. Carol spoke up, “but I’m ready for change. I woke up one day with an epiphany that I needed to make a change. That’s when I started looking for help and found you.”

Learning about lipedema

After the evaluation, I sent Carol a link to a doctor who specializes in lipedema named Karen Herbst.  I also sent a link to the Lipedema Project film entitled, The Disease They Call Fat and asked her to see if it resonated. When I saw her the next session, she said she could absolutely relate. She had never heard of lipedema before. How come no one ever told her? I explained lymphedema isn’t well-know but medical professionals are becoming more aware of the term. Lipedema, however, is even less well-known. And it’s one of the causes of secondary lymphedema.

You’re Just Fat…or Are You?

“You’re just fat.” “You need to eat less.” You need to exercise.” “You need to diet.”  “You’re lazy.” Words hurt, especially when you are already doing everything you know to do to lose weight. If you are someone who can lose weight but never as much as you want, this blog is for you. If you hit a “wall” with diets and exercise you cannot get past, this blog is for you.

Lipedema, Obesity and Swelling

I’ve written a few posts about a condition called lipedema (you can find them here, here and here). I’ve treated patients with lipedema which can progress to a condition called lipolymphedema (lipedema and lymphedema). This blog is part one of a woman’s story who has lipolymphedema and obesity. Meet Carol.

Carol struggled with weight loss

Carol* struggled with her weight, particularly when she hit her teen years. She has two brothers and a sister who use compression hose as adults, but they never struggled with weight like she did. In her late teens, a doctor put her on diet pills. She also put herself on several diets to lose weight over the years, including a 500-calorie diet (an extreme and risky way to lose weight).1 Her efforts would partially pay off.  She would lose some weight in the upper body but never much in the lower body. Commonly losing 35 pounds, weight loss would then plateau, and she could not lose any more.  Disappointed and frustrated, she felt bad about herself.  She would gain back the weight she lost and then some. Her sister commented she always looked good in her upper body. Her lower body was never proportioned to the rest of her body. As an adult, Carol even had a lap band procedure but with no subsequent weight loss.

From weight to swelling

Most of her career, Carol had a desk job & company policy required her to wear pantyhose. Around age 33, she fell & injured her left knee which resulted in arthroscopic surgery. Later, her work policy changed, and she no longer had to wear support hose.  She gladly got rid of them!  At some point, she began noticing swelling around her ankles, particularly her left ankle.  She also began having swelling in her legs.  Because of the swelling and joint pain (her knees & hip hurt), she went to a doctor for help. This doctor said she needed to lose weight. She told him she had tried dieting and exercise. She was disciplined & strict in what she ate, but she wasn’t able to lose the weight. He didn’t believe her.

Doctor after doctor

She went to another orthopedist. She described this man sitting in his chair, twirling his glasses and saying, “I can’t do anything for you. You’re just too fat.” She went to three more doctors after that consult who told her the same thing: You’re fat. You need to lose weight.  She went to one more orthopedist and described how she felt she had been discounted and [she paused as she held back tears telling me the story] treated like somebody who was just not worth their time. Someone who [she began to cry] had no value.” She described feeling like she was looked at as a second-class citizen, like someone who didn’t try.  That doctor said he didn’t want to treat her that way, but there wasn’t anything he could do for her. At that point, she stopped going to doctors.  She felt hopeless.  “If the person you place your [trust and] well-being in can’t help you, then why am I going? Why am I spending my money?” Her sister who was present in our session interrupted, “She wasn’t just hopeless, she gave up hope because she didn’t go to another doctor for years after that — for years.”

Cancer and Lymphedema Video

For the American Cancer Society

In 2020, I was searching for a deeper knowledge of how to best serve the needs of people with lymphedema. In the process, the American Cancer Society (the Dallas chapter) asked me to do a video. If you’ve had cancer and are seeking to better understand lymphedema, check out the below links. One video is in English and one video is in Spanish.

What Does March have to Do with Anything?

March is Lymphedema Awareness Month. March 6th is World Lymphedema Day. How can you make people aware of lymphedema? Three suggestions:

  • Contact your legislators
  • Contact your doctor
  • Print free infographics to hand out
Legislators

Did you know Medicare does not pay for lymphedema treatment supplies or compression? Ironically, the same government that runs Medicare passed a law called the “Women’s Health and Cancer Rights Act” requiring other insurance companies to pay for lymphedema supplies and compression due to mastectomy resulting from breast cancer.1, 2  Yet Medicare isn’t held to the same requirement. Isn’t that a double standard? Part of the discrepancy may be a result of poor awareness.  You can do something to help! Support the Lymphedema Treatment Act. The LTA website makes it easy and provides an email and platform to contact your senators and representative(s) in just a few clicks.

Doctors

This week I had the pleasure of speaking with Dr. Wei Chen, a plastic surgeon who specializes in lymphatic surgery. He commented that patients had cried in his office before because he was the first doctor to understand their condition. In Facebook feeds and reports from my own patients, I hear time and again how people with lymphedema are misdiagnosed, undiagnosed or incorrectly treated. Why is that?

Years ago I had a personal mentor whose husband was a pediatric surgeon. As I sat across the dinner table one Easter, I asked how much training physicians get in school about lymphedema. He held his hand up, separated his index finger from his thumb slightly and said, “about this much.” He explained there is so much information to cover in med school, there just isn’t time. Most of what is learned relates to immunity. Another physician (head of the acute care dept in a major Dallas hospital) contacted me to ask about care for a relative. Frustrated, he said, “they don’t teach us this stuff in med school.”

You can help your doctor become more aware by giving them a fact sheet from the LTA website or this brochure from the Lymphatic Education and Research Network (LERN). More free educational resources from the International Lymphedema Framework can be found here. You can encourage interest by suggesting they can earn CMEs. Licensure requires they obtain 48 hours of continuing medical education hours (CMEs) every two years. Physicians can earn a free CME here until 02/24/2022. They can earn up to (7) CMEs online here.

Print free infographics to hand out

If you have lymphedema, you’re bound to be asked a question now and then. Don’t be offended. You have an opportunity to educate others! If you don’t want to talk, give the inquirer this infographic. You’ll be helping spread awareness for yourself and others.

Why People with Lymphedema are Prone to Infection

Infection prevention is an important part of lymphedema maintenance. Taking good care of your skin is a primary way to prevent infection.  Lymphedematous tissue is prone to infection for a few reasons. Keep reading to find out why!

Congestion

First, a limb with lymphedema is congested as a result of poor drainage (the lymphatic system in the affected limb is mechanically or structurally damaged and cannot handle the amount of lymph fluid it needs to, so fluid backs up). When lymph fluid stagnates, it causes immune deficiency.  For example, transportation of immune cells (like lymphocytes and macrophages) to the lymphedematous limb slows down. Removal of bacteria and waste from the tissue slows down.

Think about a room in your house – let’s say your bathroom. What would happen if the sewer lines that drained your sink, shower or toilet water stopped working?  Then imagine the cleaning crew and plumber were stuck in traffic, too.  Do you have that picture in your mind?  Now you have an idea of what happens when your lymphatic system isn’t working. The scene isn’t too pretty (or healthy).

Keep in mind, lymph nodes that drain fluid from the impacted limb become diseased. Removal of antigens (foreign substances like bacteria) is impaired. So, the skin of the lymphedematous limb becomes diseased itself (causing common presentational symptoms of lymphedema).1 One scratch, puncture or sunburn could be an entry point for bacteria.

Protein-rich fluid is food for the bad guys

Second, people with lymphedema are prone to infection because the involved limb contains protein-rich fluid. This fluid is a great place for bacteria to multiply. They have the food they need (feeding off the nutrients found in lymph fluid), and the immune cells that would stop them are delayed in getting to the scene because of the swelling. In math terms:  Healthy bacterial growth + nothing to stop them = infection.

Skin disease

Third, as noted earlier, skin becomes diseased in lymphedema. One resulting symptom can be itching (pruritus). Minor trauma caused by itching can compromise skin integrity and be an entry point for bacteria. Another can be hyperkeratosis, one of the skin presentations that may occur as lymphedema progresses. Hyperkeratosis is a thickening of the skin skin due to overgrowth of keratin cells which causes elevations where bacteria can grow.

For tips on preventing infection and managing lymphedema, see December’s blog.2  Also visit the National Lymphedema Network’s Position Paper on Healthy Habits and Lymphedema as well as Risk Reduction.3 To receive tips about swelling and news about upcoming video posts, ebook updates, classes and group interactions with others, click here.

Skin Care for Infection Prevention

In last month’s blog, we talked about infection prevention. One of the strategies was to use more acidic soaps & lotions. This month, let’s investigate the composition of your skin & why those products are better for preventing infection.

Skin is composed of two main layers: the epidermis and the dermis. The outside layer (epidermis) doesn’t have blood vessels but the next layer does.  (If a skin injury or wound causes bleeding, you know its depth is at least to the dermis.)  The outer layer (sometimes called the acid mantle or hydrolipid film) has special qualities that prevent water loss & make it a good barrier to infection.  One quality is being composed of lipids which reduces water loss and keeps your skin flexible.  As the name “acid mantle” suggests, another quality is having a lower pH (or being more acidic than neutral).  That’s a good trait because we carry around harmful bacteria all the time (including bacteria that cause common infection(s) in lymphedema: Staphylococcus & Streptococcus). The acidity comes from sebum lipids (of your sebaceous glands – or oil glands) & sweat that excrete a wax-like substance to a hair follicle. 1, 2, 4

(used by permission)3

Because of the acidic-lipid properties, you need to use products that are similar to your skin – both in pH level & with characteristics that aid in reducing water evaporation. Because immunity is compromised in tissue with lymphedema, you need to take good care of your skin as it is the first line of defense. We’ll discuss product ingredients, causes of compromised skin & product recommendations in the upcoming course & ebook on lymphedema management. For now, ideal products should have a pH between 5-7, contain barrier-forming lipids (like ceramides) & possess moisturizing characteristics (such as urea). You can find additional information here.

Most soaps & lotions are more alkaline (pH of 10-11)1 which can change the pH level & bacterial resistance of your skin. Alkaline products also reduce the thickness of your skin and break down the lipid coating.2

(used by permission)5

Besides soaps & lotions, other factors impact skin integrity. Some of these factors include: sun, hydration, nutrition, smoking, obesity, medications & age. So use sunscreen, drink water, eat healthy, don’t smoke, lose weight, be healthy — & stay young (let me know if you figure that one out!).

In February, we’ll answer the question: Why People with Lymphedema are Prone to Infection.

Infection Prevention

Common infections in lymphedema are cellulitis and erysipelas.  As with most infections, they present with redness, swelling and warmth. Pain and/or blisters may or may not be associated.

  • Cellulitis is an infection of the deep subcutaneous tissue due to the streptococci bacterium (or other bacterium such as staphylococcus aureus). Cellulitis has a slower onset and the redness has an undefined, vague border. This infection is more often found in the legs.
  • Erysipelas (also called St. Anthony’s fire) is an infection of the upper layers of skin that tends to recur. It is caused by the streptococcal bacterium and has a faster onset than cellulitis. The associated redness has a defined or sharp edge (like a burn) and is slightly raised. It usually begins with chills followed by a high fever and may include severe malaise (pain), nausea and headache.1,3, 5

These two infections can co-exist as they involve different layers of the skin.  But whether there are two infections or one, in the U.S. they are commonly lumped under one umbrella and called “cellulitis.”  For our purposes, cellulitis is simply a skin infection causing redness, swelling and warmth. If you have lymphedema and you have symptoms of infection, you need to get to the doctor promptly. Each infection further damages your already impaired lymphatic system — and if left untreated, can be fatal.

How do you get cellulitis? We all have bacteria that normally live on our skin. When something causes a break in your skin (an insect bite, an animal bite, a sunburn, a scratch, a thorn, etc.), bacteria have a way inside your body. Most of the time, your immune system fights them off. But even the healthiest among us can be susceptible. In lymphedema, immunity is reduced in the involved extremity. As a result, a person with lymphedema is predisposed to getting cellulitis (recurrent infections are common in stage III lymphedema).  It’s also possible to get cellulitis and have no apparent external trauma to your skin. This may be due to skin being more permeable (such as in a distended, swollen limb). Other risk factors include being older, having a serious illness or an immunocompromised state, liver or kidney disease, venous insufficiency, 2 or any condition that may impact sensation (such as neuropathy or paralysis).

How can you prevent cellulitis?  If you have lymphedema, wear your compression to control swelling. Additionally: 3, 4

  • Avoid skin punctures (wear gloves during gardening, don’t roughhouse with pets, use bug spray)
  • Avoid scratching (try gently rubbing an itch)
  • Wear gloves when working with chemicals or hot dishwater
  • Wear protective mitts when working near a hot stove
  • Wear a thimble if sewing
  • Don’t cut cuticles and avoid nail salons
  • Use sunscreen
  • Treat any skin condition that may compromise your skin (such as athlete’s foot, eczema or psoriasis)
  • Use more acidic soaps and lotions

In January’s blog, we’ll talk about the best soaps and lotions for lymphedema.

Veterans Day and Your Lymph System

(How Your Lymphatic System Defends Your Body and Keeps You Safe)

Several years ago I came across my grandfather’s old Navy manual.  He enlisted in the Navy underage, determined to join, near the time of Pearl Harbor.  The attack against Pearl Harbor forced the United States into World War II.  His subsequent years saw a lot of action – events he would never talk about.  Only in reading his journal entries years later (in the front and back pages of his handbook) did I gain greater insight into what he experienced. He wrote of being attacked by bombers and torpedo planes in the early morning hours. “[A]bout two o’clock they dived at us just missed us with a torpedo.” He continued, “May our luck hold out and God watch over us in time of battle which is very often.”  I knew he had a fear of water but only understood why later: He had been knocked into the ocean during an enemy attack against his destroyer warship.  Ultimately, he was honorably discharged after developing post-traumatic stress disorder (PTSD).

Many times we go about our daily lives not giving thought to the sacrifices those in our military make (in order that we might remain free and live each day as we do). Their sacrifices include missing the comfort of home; separation from loved ones; missing birthdays, anniversaries and holidays; missing a child’s milestones; potentially sustaining lifelong mental, emotional and physical trauma; and, some even sacrifice their very life on our behalf.  May President Reagan’s words ring true this month (and every month), “We will always remember. We will always be proud. We will always be prepared so we may be always free.” 8

To all who have served (and presently serve) in our armed forces: Thank you.

In honor of Veterans Day, how does your lymphatic system play a role in defending your body and keeping you safe?

Men and women in the Air Force, Army, Navy, Marine Corps, Coast Guard, and recent Space Force as well as the National Guard preserve our freedom by securing our country, protecting our interests, preventing potential attacks and fighting on our behalf when we do go to war. We even have elite special operations forces (highly trained and skilled individuals with specialized knowledge). To best perform these functions, the military must be strong, healthy and able to respond swiftly. In his 1793 State of the Union Address, President George Washington said, “[I]f we desire to secure peace …it must be known that we are at all times ready for war.” 1 The best way to prevent an opportunist from gaining a foothold is to always be strong, prepared, and willing to act, if necessary.

Your body’s defense system is similarly made up of various branches creating its own armed forces:  Your skin, stomach (acid) and digestive system, tears, mucus, cilia (hair-like projections), saliva and lymphatic system make up your “armed forces.”  The lymphatic system has structural components made of vessels and organs. These include:

  • lymph vessels – lymph capillaries, precollectors, collectors (lymphangions) and trunks
  • primary lymph organs – red bone marrow (housing stem cells that become lymphocytes) and the thymus gland
  • secondary lymph organs – spleen, lymph nodes (such as tonsils) and mucosa-associated lymphatic tissue (membranes that line the GI tract like Peyer’s patches, respiratory airways, urinary tract and reproductive tract). 3,4

Your body fends off attacks from an enemy such as a pathogen or microbe (like a virus or bacteria) by neutralizing it, repairing damage (from bumps, cuts, burns, chemicals, etc.) and eliminating abnormal or degenerative cells (like cancer).  The body provides two types of defense:

Nonspecific3 – A general protection against invasion by pathogens through physical barriers (skin and mucus membranes), production of antimicrobial chemicals to inhibit microbe growth, natural killer cells (a.k.a. white blood cells or lymphocytes), phagocytosis (ingesting a pathogen), fever and inflammation.

Examples: Thick mucus and cilia filter air and trap microbes, dust and pollutants. Tears bathe the eye surface, washing away microbes as you blink. Cells that get infected with a virus produce messages (proteins called interferons) that signal other cells of the invasion. Many lymphatic cells (macrophages, B and T lymphocytes) produce these proteins. Non-infected cells get the message and ready themselves for attack (i.e. they make proteins to inhibit their own invasion of a virus which replicates itself using the cell). The blood contains a group of soldiers (i.e. inactive proteins) that activate themselves to bolster defenses (by enhancing immune, allergic and inflammatory reactions). Some soldiers even combine forces to punch holes in the plasma membrane of a microbe (cytolysis) causing it to rupture. How awesome is that?

If physical barriers and antimicrobial chemicals don’t work, the next lines of defense are natural killer cells and phagocytes (WBCs or lymphocytes) which destroy intruders. Killer cells patrol the body, interacting with other cells (checking “ID cards”). If a cell doesn’t match up (like a cancer cell)? It’s “Hasta la vista, Baby.” 6  Some phagocytes also patrol the body while others remain stationed at a post (in tissue). They ingest (imprison) an invader, unleash chemicals to kill the microbe and digest the remains. What a rough way to go! Anything that can’t be degraded is contained in residual bodies (mini-prisons) which are expelled into the interstitial space and cleaned up by the lymph capillaries.

Finally, there is inflammation and fever.  If invaders have caused tissue damage, the body responds with an inflammatory response (a loud siren) resulting in widening of roads (enlarging blood vessels, a process called vasodilation) and more eagerly opening gates (increasing blood vessel permeability), to allow soldiers, clean up personnel and paramedics (antibodies, phagocytes and clot-forming chemicals in blood) to enter the trauma zone.

Specific3 – A specific, adapted defense response (immunity) to a particular pathogen (called an antigen) is launched by the lymphatic system (T and B lymphocytes) and is the most potent.5 This takes some smarts!  It is sort of like profiling (antigens are external molecular structures or characteristics that identify the pathogen).  The lymphatic system not only recognizes the invader but remembers it next time around and responds even faster. These are your “elite special operations forces.”  T and B cells develop in red bone marrow. B cells remain there while T cells migrate to the thymus to complete their training (development). Before either cell leaves their training base, it becomes highly trained and skilled with specialized knowledge (in the form of distinctive surface proteins) in order to recognize specific enemies. In fact, “[b]efore a particular antigen ever enters the body, T and B lymphocytes that can recognize and respond to that intruder are ready and waiting.”7 That kind of preparedness would make President George Washington proud!

When an antigen is recognized, B and T cells respond in two ways: cellular or humoral. In cellular, some T cells become killer cells and directly attack. This is sort of like a reconnaissance mission during which T cells scout the body for enemies and once identified, attack.  In humoral, B cells become plasma cells which make and secrete proteins (antibodies or immunoglobulins).  These bind to and inactivate a particular antigen. This is sort of like a reconnaissance mission during which B cells disable and neutralize the enemy.

How can your lymphatic system “always be strong, prepared, and willing to act?” By you following a healthy regimen:  Get plenty of rest. Eat healthy. Reduce stress. Practice good hygiene and wash your hands often. Exercise. Maintain a healthy weight. Don’t do unhealthy things (drinking too much, smoking, etc.). And, given that lymphatics slow down as we age (restricting the transport of antibodies), 2 consider getting a manual lymph drainage massage from time to time.
