Swelling in the hands, feet, ankles, or legs is common and is medically known as edema. It occurs when excess fluid collects in the body tissues. While occasional swelling may be temporary, persistent or unexplained swelling should not be ignored.
Swelling can occur after standing or sitting for long periods, travelling for several hours, eating too much salt, or during hot weather. However, it can also be a sign of an underlying medical condition.
Kidney problems may cause the body to retain excess salt and water, resulting in swelling of the feet, ankles, or face. Heart problems, particularly heart failure, can also lead to fluid accumulation in the legs. Liver disease, thyroid disorders, poor circulation, certain medications, infections, and injuries are other possible causes.
If swelling occurs suddenly, affects only one leg, or is associated with pain, redness, warmth, breathlessness, chest pain, or reduced urine output, medical evaluation is important.
Do not take medicines to reduce swelling without identifying the cause. Proper treatment depends on the underlying condition.
Swelling is a symptom, not a disease. Finding the cause is the key to proper treatment.
