Treatment focuses on managing symptoms through compression, exercise, and proper skin care
With proper management, most people with lymphedema can live active, fulfilling lives
Overview
Lymphedema is a long-term condition that causes swelling in your body's tissues. This happens when your lymphatic system can't drain lymph fluid properly. The lymphatic system is like your body's drainage network. It helps fight infection and removes extra fluid from your tissues.
When this system gets damaged or blocked, lymph fluid builds up. This causes swelling, usually in your arms or legs. The swelling can be mild at first but often gets worse over time without treatment.
About 10 million Americans have lymphedema. It affects people of all ages, from babies to older adults. Women are more likely to develop it than men, especially after cancer treatment. While there's no cure, proper treatment can help control symptoms and prevent complications.
The condition can make daily activities harder. Your arm or leg may feel heavy or uncomfortable. But with the right help and treatment, you can manage lymphedema and stay active.
Symptoms & Signs
Lymphedema symptoms usually develop slowly over time. The swelling may come and go at first, but it typically becomes constant without treatment.
Primary Symptoms
Swelling in arms or legs - Usually starts in hands or feet and moves up the limb
Feeling of heaviness or fullness - Your affected limb may feel tight or uncomfortable
Restricted range of motion - Joints may feel stiff or hard to move normally
Recurring infections - Skin infections happen more often in the affected area
Hardening and thickening of skin - Over time, skin becomes firm and difficult to pinch
Many people notice their clothes or jewelry fit tighter on the swollen side. Some see that one arm or leg looks bigger than the other. You might also notice that the swelling gets worse later in the day or after activity.
Skin changes happen slowly over time. The skin may become red, warm, or shiny. You might see small bumps or ridges on your skin that look different from normal.
When to Seek Care
Watch for sudden increases in swelling, red streaks on your skin, or fever. These could be signs of a serious infection called cellulitis. Also see a doctor if you notice any swelling that doesn't go down with rest or elevation.
Call your doctor if the swelling spreads to a new area. Report any signs of skin breakdown or open sores. Tell your doctor if your compression garments no longer fit properly due to increased swelling.
When to Seek Immediate Care
Get emergency help if you have sudden severe swelling, high fever, red streaks spreading from the swollen area, or signs of serious infection.
Causes & Risk Factors
Lymphedema has two main types: primary and secondary. Primary lymphedema happens when you're born with lymphatic system problems. Secondary lymphedema develops when something damages your lymphatic system later in life.
Cancer treatment is the most common cause of secondary lymphedema in developed countries. Surgery to remove lymph nodes, radiation therapy, and chemotherapy can all damage the lymphatic system. Understanding the differences between similar conditions helps doctors make accurate diagnoses.
Infections, injuries, and certain medical procedures can also cause lymphedema. In developing countries, parasitic infections are a leading cause. The condition can develop immediately after surgery or appear months or even years later.
Some people develop lymphedema after burns or severe accidents. Major injuries can scar lymph vessels and stop them from working properly. Even small injuries can sometimes trigger lymphedema in people at risk.
Infections like cellulitis can damage your lymph system over time. If you get the same infection multiple times, your risk goes up. Travel and surgery in other countries may also increase your risk of lymphedema.
Age
Risk increases with age, especially after 40
Genetics
Family history of lymphedema increases risk
Lifestyle
Obesity and lack of movement worsen symptoms
Other Conditions
Cancer treatment, heart disease, kidney problems

Diagnosis
Medical History & Physical Examination
Your doctor will ask about your symptoms, family history, and any previous surgeries or medical treatments. They'll examine the affected area, measuring the size of your limbs and checking your skin. The doctor will also feel for lymph nodes and assess your range of motion.
During the physical exam, your doctor may press on the swollen area to see if it leaves an indentation. They'll also look for signs of infection and check the texture of your skin.
Your doctor will compare both arms or both legs to see the difference. They may ask you to keep a swelling diary before your visit. This helps them understand how your swelling changes throughout the day.
Diagnostic Testing
Lymphoscintigraphy - A special scan that shows how lymph fluid moves through your system
CT or MRI scans - These create detailed pictures to rule out other causes of swelling
Ultrasound - Uses sound waves to check for blood clots that might cause similar symptoms
Bioimpedance spectroscopy - Measures electrical currents to detect fluid buildup in tissues
Most doctors diagnose lymphedema based on your medical history and physical exam. Scans are usually only done to rule out other problems. Testing is quick and painless in most cases.
Treatment Options
Treatment for lymphedema focuses on reducing swelling and preventing complications. The goal is to move lymph fluid out of the affected area and keep it from building up again.
Conservative Treatments
Complete decongestive therapy (CDT) - Combines manual drainage, compression, exercise, and skin care
Compression garments - Special sleeves or stockings that apply gentle, steady pressure to move fluid
Manual lymphatic drainage - A specialized massage technique performed by trained therapists
Exercise programs - Gentle movements that help pump lymph fluid through your system
Most people start with these basic treatments first. They work well for many people and have no serious side effects. Your doctor or therapist will teach you how to do them at home.
Starting treatment early gives you the best results. The sooner you begin, the easier it is to control swelling. Many people see improvement within weeks of starting treatment.
Advanced Treatments
Pneumatic compression devices - Machines that inflate and deflate to massage the affected limb
Surgical procedures - Operations to create new drainage paths or remove excess tissue when conservative treatment fails
These advanced options are used when basic treatments don't help enough. Surgery is usually only done after trying other treatments for a long time. Talk to your doctor about whether advanced treatment might help you.
Living with the Condition
Daily Management Strategies
Keep your skin clean and moisturized to prevent infections. Avoid cuts, burns, and insect bites on the affected limb. Wear your compression garments as prescribed by your doctor. Watch for changes in swelling and report them to your healthcare team. Proper lifestyle modifications can significantly improve your quality of life.
Develop a daily routine for your lymphedema care. Set reminders to wear your compression garments at the right times. Keep all appointments with your therapist and doctor so they can monitor your progress.
Try to stay positive about managing your condition. Many people find that support groups help them feel less alone. Talking with others who have lymphedema can give you helpful tips and encouragement.
Exercise & Movement
Low-impact activities like swimming, walking, and gentle stretching are usually safe and helpful. These exercises help move lymph fluid through your system. Always wear compression garments during exercise if your doctor recommends them. Avoid activities that might injure the affected limb or cause overexertion.
Start slowly with any new exercise program. Talk to your doctor before starting a new activity. You may need to adjust your routine based on how your body responds.
Stay as active as possible within your limits. Movement helps prevent your swelling from getting worse. Being active also helps you feel better and keeps your body healthy.
Prevention
Protect your skin from cuts, burns, and infections through careful daily care
Maintain a healthy weight to reduce stress on your lymphatic system
Exercise regularly with gentle, low-impact activities approved by your doctor
Follow all post-surgery care instructions if you've had lymph nodes removed
Seek prompt treatment for any skin injuries or signs of infection in the at-risk area
Use sunscreen to protect your skin from burns on the affected limb. Wear long sleeves when gardening or doing yard work to prevent scratches. Keep your nails trimmed short and smooth to avoid accidental skin damage.
Elevate your arm or leg when sitting down to help with swelling. Use a pillow to prop it up comfortably. Try to avoid sitting or standing in one position for too long without moving.
Stay aware of your swelling patterns and what makes it worse. Keep track of activities that seem to increase swelling. Use this information to plan your days and prevent problems before they happen.
