What causes leg swelling in elderly people, and how should it be managed?

Generally, leg edema in the elderly may be caused by physiological factors or pathological conditions such as varicose veins, heart failure, etc., and treatment should be tailored according to the specific cause. The details are as follows:

1. Physiological Factors

If elderly individuals remain seated for prolonged periods, it may lead to poor circulation in the lower limbs, resulting in leg edema. Excessive fluid intake can also contribute. This type of edema usually does not require treatment and resolves with appropriate physical activity.

2. Pathological Factors

1) Varicose Veins

Varicose veins result from impaired blood return due to venous obstruction or reflux, leading to blood congestion and swelling in the lower limbs. Patients are advised to modify their lifestyle—avoiding prolonged standing or sitting—and elevate the affected limb when lying down. Compression therapy, as recommended by a physician, may include elastic stockings, compression bandages, or pneumatic compression devices.

2) Heart Failure

Heart failure is relatively common in the elderly and can cause lower limb edema. Patients are encouraged to stay physically active and take medications as prescribed, such as furosemide tablets or losartan potassium/hydrochlorothiazide tablets.

In addition, other possible causes include lymphatic vessel blockage, nephrotic syndrome, rheumatoid arthritis, systemic lupus erythematosus, among others. It is recommended that patients seek timely medical attention upon experiencing symptoms to avoid delayed treatment. Additionally, maintaining a light diet and ensuring adequate rest are important in daily life.
