Lower Limb Swelling: Causes, Diagnosis and Treatments

Lower limb swelling usually occurs due to an abnormal accumulation of fluid in the tissues of the lower limb. The medical term for swelling of the legs from excess fluid in the tissues is peripheral edema. The persistent cleft of a swollen leg after finger pressure is known as pitting edema.

Leg swelling should not always be assumed as peripheral edema. Diagnosis should be made through careful examination and relevant tests. Bilateral swelling is usually due to systemic diseases, while unilateral swelling is typically caused by local trauma, venous disease, or lymphatic disease.

Unilateral leg swell is most often due to local causes (eg, deep vein thrombosis or cellulitis). However, bilateral swell from systemic causes can be much more obvious on one side than the other and may therefore appear to be unilateral swell.

Causes Of Lower limb Swelling

There are many potential causes of swollen feet, legs, and ankles. It occurs in most cases as a consequence of such lifestyle causes, such as:

Being overweight

Excess body mass can decrease blood circulation, causing fluid to build up in your feet, legs, and ankles.

Standing or sitting for long periods

When muscles are inactive, they cannot pump body fluids to the heart. Water and blood retention can trigger swell in the legs.


Other possible causes

Natural hormonal changes

Fluctuating levels of estrogen, and progesterone can reduce circulation in the legs and lead to swelling. These changes in hormone levels can occur during pregnancy and a woman's menstrual cycle.

A blood clot in the leg

A blood clot is a group of blood that is in a solid-state. When a blood clot forms in a vein in the leg, it can affect blood flow and cause swell and discomfort.

Injury or infection

An injury or infection affecting the foot, leg, or ankle causes increased blood flow to the area. This presents a swell.

Pericarditis

This is long-term inflammation of the pericardium, which is the sac-like membrane that surrounds the heart. Breathing problems and considerable chronic bulge of the legs and ankles are caused by the disease.

Lymphoedema

Lymphedema, also called lymphatic obstruction, causes blockages of the lymphatic stream. This system is made up of lymph nodes and blood vessels that help transport fluid throughout the body. A blockage in the lymphatic system causes the tissues to swell with fluid, causing swelling in the arms and legs.

Preeclampsia

During pregnancy, this disease causes increased blood pressure. Increased blood pressure can lead to poor circulation and swollen face, hands, and legs.

Cirrhosis

This refers to severe scarring of the liver, which is often caused by alcohol abuse or an infection (hepatitis B or C). High blood pressure and low circulation in the feet, legs, and ankles may be caused by the disorder.
