Inflammation is a natural process that plays a vital role in healing. It's the body’s way of responding to injury and infection. However, when inflammation becomes prolonged or chronic, it can prevent full recovery and contribute to various health problems.
In people with lymphedema, inflammation is a constant underlying issue. While it's easy to notice the swelling in the limbs, it's harder to understand what's happening beneath the surface. Extra fluid, waste products, and proteins build up in the tissues, causing ongoing inflammation that can make lymphedema harder to manage. Lifestyle and diet choices can worsen this inflammation, leading to more swelling and making healing more difficult.

1. Acute inflammation
1. Acute Inflammation
Acute inflammation is the body’s initial response to injury or infection. It’s a complex process that involves chemicals, immune cells, and hormones designed to stop bleeding, fight infection, and repair damaged tissue. While it can be uncomfortable, acute inflammation is essential for healing.
Causes of Acute Inflammation
Acute inflammation can occur anywhere in the body and is typically triggered by:
Bacteria or viruses
Foreign objects (like splinters or dirt)
Injury (cuts, scrapes, sprains)
Exposure to chemicals or radiation (e.g., UV rays from the sun or radiation therapy)
When an injury occurs, the immune system responds by sending cells to the affected area. These cells work to fight infection, remove damaged tissue, and promote healing.
Common Signs of Acute Inflammation:
Redness: Increased blood flow to the area
Warmth: Blood rushing to the area also raises temperature
Pain: Chemicals released during inflammation irritate nearby nerves
Swelling: Fluid leaks from blood vessels into tissues, causing puffiness
Loss of Function: Swelling and pain can limit movement, especially near joints
Normal Function of the Lymphatic System
The lymphatic system plays a key role in the healing process. It helps drain excess fluid and waste products from the tissues, transports harmful substances to lymph nodes for neutralization, and supports the immune system’s overall function.
2. Chronic Inflammation
While acute inflammation is short-term and essential for healing, chronic inflammation occurs when the process persists for months or even years. Chronic inflammation can start even without an obvious injury and may occur for several reasons.
Some common causes include:
Persistent infections that never fully resolve
Autoimmune conditions like rheumatoid arthritis or lupus, where the immune system mistakenly attacks the body’s own tissues
Obesity: Excess fat, especially abdominal fat, has been linked to chronic inflammation
Lymphedema: New research shows chronic inflammation is a factor in lymphedema progression
If inflammation lasts too long, it can lead to tissue damage and contribute to various chronic diseases.
3. Why Should We Care About Chronic Inflammation?
Chronic inflammation can have far-reaching effects on overall health. It can be subtle and may not always present noticeable symptoms or be mistakenly associated with the aging process. However, over time, it can lead to various health issues.
Here are some common signs and symptoms that can be associated with chronic inflammation:
Fatigue
Persistent tiredness or exhaustion, even after adequate rest, is a common sign of chronic inflammation. It can occur because the body’s immune system is constantly activated.
Pain
Ongoing pain in the body, particularly in joints or muscles, is another sign. This can resemble the discomfort associated with conditions like arthritis. Pain may be dull or sharp and can get worse with movement.
Swelling
Chronic inflammation can cause the body to retain fluid, leading to puffiness or swelling, particularly in the limbs or joints. It can also be a factor in the progression of lymphedema through increases in swelling as well as underlying tissue changes.
Digestive Issues
Chronic inflammation can affect the gut, leading to symptoms like bloating, constipation, diarrhea, or irritable bowel syndrome (IBS). It may also contribute to conditions like Crohn’s disease or ulcerative colitis.
Frequent Infections
If the immune system is constantly active due to chronic inflammation, it can become less efficient, leading to an increased risk of infections or illness.
Skin Problems
Skin conditions such as rashes, eczema, or psoriasis may be linked to ongoing inflammation. Redness and irritation may also be present.
Mood Swings and Depression
Chronic inflammation can affect brain function and mood regulation. People with chronic inflammation may experience anxiety, depression, or irritability. This is because inflammatory molecules can influence neurotransmitter function in the brain.
Weight Gain or Difficulty Losing Weight
Inflammation, especially around the abdominal area, is linked to insulin resistance and hormonal imbalances that can make it difficult to lose weight. The body’s inflammatory response can also lead to increased fat storage.
Heart Issues
Chronic inflammation is a key factor in heart disease. It can lead to conditions like atherosclerosis (hardening of the arteries), which can cause chest pain, high blood pressure, and increase the risk of heart attacks or strokes.
Reduced Mobility or Stiffness
Persistent joint pain, stiffness, or swelling can result in difficulty moving certain parts of the body. This is commonly seen in inflammatory conditions like rheumatoid arthritis.
Headaches
Chronic inflammation can cause frequent headaches or migraines. This may be related to systemic inflammation affecting the nervous system.
Brain Fog
Chronic inflammation can impair cognitive function, leading to symptoms like memory problems, difficulty concentrating, and a general sense of mental confusion or "brain fog."
Sleep Disturbances
Chronic inflammation may interfere with sleep, causing insomnia or poor-quality sleep. This is due to inflammatory cytokines that can disrupt the body’s natural sleep-wake cycle.
Elevated Blood Sugar Levels
Ongoing inflammation can contribute to insulin resistance, which may lead to higher blood sugar levels and eventually increase the risk of developing Type 2 diabetes.
Increased Risk of Cancer
Chronic inflammation is associated with an increased risk of developing certain types of cancer. The continuous release of inflammatory molecules can cause DNA damage, which contributes to tumour growth.
Managing Chronic Inflammation
What fuels chronic inflammation? While it is associated with chronic conditions such as arthritis, there are many factors, including environmental exposures, poor diet, lack of exercise, stress, and even genetics, that can contribute to ongoing inflammation in the body. But there’s good news: lifestyle changes can help reduce inflammation and potentially reduce the risks of developing or worsening chronic conditions.
Steps to Reduce Inflammation:
Adopt an anti-inflammatory diet: Focus on whole, nutrient-rich foods like fruits, vegetables, whole grains, lean proteins, and healthy fats. Avoid processed foods, excess sugar, and trans fats.
Exercise regularly: Moderate physical activity has been shown to reduce inflammation.
Manage stress: Chronic stress can contribute to inflammation. Practices like mindfulness, yoga, and meditation can help.
Get enough sleep: Lack of sleep can increase inflammation. Aim for 7-9 hours each night.
Quit smoking and limit alcohol: Both can promote inflammation.
Maintain a healthy weight: Obesity is a significant factor in chronic inflammation.
Understanding the nature of chronic inflammation is key to managing health, particularly for those with lymphedema. While acute inflammation is necessary for healing, chronic inflammation is harmful and can contribute to a range of diseases. Lifestyle and dietary choices play a crucial role in either adding to, or reducing inflammation, which means that taking care of your body through mindful choices can improve overall health and help manage conditions like lymphedema.
