Lipedema vs. Lymphedema: How to Tell the Difference

Two conditions, lipedema and lymphedema, can both cause swelling in the arms and legs, and they are often confused with each other. But they are actually very different diseases with different causes, different symptoms, and different treatments. Getting the right diagnosis matters because the treatment for one may not work for the other. Here is a simple guide to help tell them apart.

What Is Lipedema?

Lipedema is a condition where abnormal fat builds up under the skin, usually in the legs and sometimes in the arms. It almost always affects women and typically starts during times of hormonal change; like puberty, pregnancy, or menopause. Researchers believe it is linked to genetics and hormones, since many women with lipedema have a female family member with the same condition. It is estimated to affect about 10% of women, though many go undiagnosed for years.

What Is Lymphedema?

Lymphedema happens when the lymphatic system, the body’s network for draining fluid, is damaged or does not work properly. This causes fluid to build up in the tissues, leading to swelling. It can affect both men and women. Lymphedema can be something a person is born with (primary lymphedema) or it can develop after surgery, radiation, infection, or injury that damages the lymph vessels (secondary lymphedema). One of the most common causes is cancer treatment, especially for breast cancer.

Key Differences at a Glance

Here are the main ways to tell lipedema and lymphedema apart:

• Who it affects: Lipedema occurs almost exclusively in women. Lymphedema can affect anyone, men and women alike.
• When it starts: Lipedema usually begins at puberty, during pregnancy, or around menopause. Lymphedema can start at any age, often after surgery, radiation, or infection.
• Where the swelling is:  Lipedema causes swelling that is usually symmetrical (both legs look the same) and spares the feet.  There is often a noticeable “cuff” or “bracelet” effect right above the ankles. Lymphedema can affect just one limb and typically includes the hands or feet.
• Pain and tenderness: Lipedema is usually painful and tender to the touch. Lymphedema is often painless, especially in the early stages.
• Bruising: People with lipedema tend to bruise very easily in the affected areas. Easy bruising is not a typical feature of lymphedema.
• Pitting: When you press on the swollen area, lymphedema often leaves a dent (called “pitting”), especially in the early stages. Lipedema usually does not pit.
• Stemmer sign: In advanced lymphedema, a doctor cannot pinch a fold of skin on the top of the second toe, this is called a positive Stemmer sign and is a hallmark of lymphedema. This sign is not present in lipedema.
• Skin changes: Lymphedema can cause the skin to become thick, hard, and warty over time. The skin in lipedema usually stays soft and normal in texture.
• Response to diet and exercise: Dieting and exercise do not reduce the abnormal fat in lipedema-affected limbs, even though a person may lose weight elsewhere. Lymphedema swelling can sometimes improve with specific therapies but also does not respond to diet alone.
• Response to elevation: Elevating the legs can help reduce lymphedema swelling, but it usually does not help lipedema.

Can You Have Both?

Yes. Over time, untreated lipedema can progress and begin to affect the lymphatic system. When this happens it is called lipolymphedema, a combination of both conditions. This makes diagnosis and treatment more complex, which is why early recognition is important.

How Are They Diagnosed?

Both conditions are diagnosed mainly through a medical history and physical exam. A doctor will look at where the swelling is, whether it is symmetrical, whether the feet are involved, and whether the area is painful or tender. In some cases, imaging tests like ultrasound or lymphoscintigraphy (a special scan that shows how the lymph system is working) may be used to confirm the diagnosis, especially if the two conditions are hard to tell apart.

How Are They Treated?

The treatments for these two conditions overlap in some ways but differ in others:

• Lymphedema is treated with a program called complete decongestive therapy (CDT). This includes gentle massage (manual lymphatic drainage), compression bandaging or garments, exercise, and careful skin care. In some cases, surgery or pneumatic compression devices may be recommended.
• Lipedema treatment focuses on managing symptoms and may include compression garments, specialized exercise (especially water based exercise), and dietary changes such as anti-inflammatory diets. The most effective treatment for lipedema is tumescent liposuction, a surgical procedure that removes the abnormal fat tissue and has been shown to provide long lasting pain relief and improved quality of life.

The Bottom Line

Lipedema and lymphedema may look similar on the surface, but they have different causes and require different approaches to care. If swelling in the legs or arms is causing pain, tenderness, or easy bruising (especially if it started around puberty and spares the feet) lipedema should be considered. If swelling involves the hands or feet, is one sided, or developed after surgery or cancer treatment, lymphedema is more likely. Either way, seeing a healthcare provider who is familiar with these conditions is the best first step toward getting the right diagnosis and treatment.
