Lymphedema is swelling caused by fluid that collects in the arm or leg when lymph does not drain properly. It often follows surgery or cancer treatment and can lead to skin damage, ulcers and infection. Compression therapy, wound care and, for some patients, surgery can bring it under control.
Lymphedema is a long-term swelling that often gets worse with time. It happens when fluid rich in protein collects in the tissues because something has damaged or blocked the lymphatic system. Normally this system drains extra fluid and protein out of the tissues and back into the blood.
It can affect any part of the body, but the arms and legs are the most common sites. Without treatment the skin thickens, infections keep coming back, wounds may not heal and moving around gets harder. Many patients also feel self-conscious about how the limb looks. If doctors find it early and treat it properly, patients can avoid most of these problems and get back their comfort and normal function.
The lymphatic system is a network of thin vessels and small glands called lymph nodes. It keeps the body’s fluid in balance and helps fight infection. It picks up extra fluid, protein and waste from the tissues and carries them back into the bloodstream. When this drainage fails, fluid collects in the tissues. That build-up is lymphedema.
Lymph nodes also filter out bacteria, viruses and other unwanted material. If surgery, injury or radiation removes or damages the nodes in an area, drainage from that whole area suffers.
There are two main types:
This type is rare. The lymphatic system does not develop normally, and in some families it passes from parent to child. It can show up at birth, around puberty or later in adult life. In these patients the lymph vessels may be too few, too small or missing altogether.
This is the more common type. Here something damages a lymphatic system that used to work normally. The usual causes are:
Whatever the cause, the swelling usually gets worse without treatment.
Lymphedema can come on slowly or appear suddenly, depending on the cause. The first signs are often mild and easy to miss, but spotting them early helps prevent complications.
In the early stages the swelling is usually soft. Later it becomes firm, and without treatment the skin can turn leathery, break down into ulcers and start to smell.
Doctors grade lymphedema by how severe it is:
Timely treatment can reverse the early stages. But advanced stages need a mix of surgical and non-surgical treatment.
Without proper treatment, lymphedema can lead to serious problems:
These problems affect more than the body. They can also take a toll on mood and social life.
Most of the time the surgeon makes the diagnosis by examining the patient. Scans help in some cases:
First, the vascular surgeon looks at the pattern of swelling, the skin texture, any ulcers or leaking fluid, and the difference in size between the two limbs.
This rules out other causes of swelling, such as deep vein thrombosis or a mass.
The doctor injects a small amount of radioactive dye and follows it to see how lymph flows and where it stops. The test helps confirm primary lymphedema and plan surgery.
These scans show what the swollen tissue is made of and help rule out other causes, including cancer.
There is no permanent cure for lymphedema, but a mix of non-surgical and surgical treatment keeps it well under control. Early cases usually do well without an operation. Advanced cases need a more planned approach.
This is the main treatment for lymphedema.
Most patients need compression for life, so the garment has to be the right size and give the right pressure for the stage of the disease.
When the skin has broken down or ulcers have formed:
Good wound care keeps infection away and helps wounds heal faster.
In some patients, the surgeon joins tiny lymph vessels to nearby veins so the fluid can get around the blockage. This operation is called lymphaticovenular anastomosis (LVA). It is minimally invasive and works best in early to moderate disease.
In advanced lymphedema, when the limb is very large and the skin has hardened, the surgeon removes the extra tissue. This makes it easier to move, cuts down leakage and makes the limb easier to keep clean. Badly ulcerated areas may also need a skin graft.
Treatment often combines compression, surgery, wound care and physiotherapy. Changes in daily habits and learning how to look after the limb make a big difference over the long term.
What you do at home makes a big difference in keeping the results and avoiding flare-ups.
The right treatment keeps lymphedema under control. An early diagnosis helps avoid permanent damage. When the swelling follows cancer treatment or an infection, early treatment improves both comfort and appearance.
It is a lifelong condition, but most patients go back to their normal routine with proper care. Regular follow-up with a vascular surgeon helps track progress and prevent complications.

Seeing a vascular surgeon early can prevent permanent damage and helps the limb work better.
Evening consultations are at Vascular Care n Cure Clinic, Andheri East, Monday to Saturday, 5 to 7 pm. I also see patients in OPD at these hospitals; each page has the OPD day, timing and booking number:
There is no permanent cure, but it can be controlled. Early stages respond well to compression and skin care; advanced stages may also need surgery.
Removal of lymph nodes or radiation can damage lymph drainage, so fluid collects in the arm. Early assessment helps stop it worsening.
In most cases, yes. Compression is the mainstay of treatment, and the garment must be the right size and pressure for your stage.
Lymphaticovenular anastomosis (LVA) connects small lymph vessels to nearby veins in selected patients. In advanced cases, debulking surgery removes excess tissue.
Yes. Vascular surgeons treat diseases of the arteries, veins and lymphatic vessels. Care includes ruling out a vein problem or clot as the cause of the swelling, compression therapy, skin and wound care, and surgery for selected patients.
Lymphedema can look like simple swelling, but it is a long-term vascular condition that needs proper medical care and sometimes surgery. At our clinic we focus on an accurate diagnosis, teaching patients how to manage it, non-surgical treatment, and surgery where it is needed.
