Why do my calves swell in the afternoon?

There are many reasons why the calves may swell in the afternoon. People with nephritis or kidney disease may experience calf swelling. Patients with heart disease may suffer from right heart failure due to some reasons, resulting in blood not being able to return and causing edema. Swelling may also occur after being bitten by some insects containing toxic liquids.

1. Renal edema. In patients with acute nephritis, chronic nephritis or kidney disease, due to reduced renal blood flow, sodium and water retention, increased capillary permeability, and excessive protein loss in the urine, the plasma colloidal osmotic pressure will be reduced, causing fluid accumulation in the tissue spaces and causing edema. 2. Cardiogenic edema. When right heart failure occurs in various heart diseases, venous blood cannot return smoothly, causing increased pressure in the veins, and body fluids leak into the tissue spaces, causing edema.

3. Hepatic edema. Factors such as liver damage in cirrhosis, obstruction of portal vein return, increased portal vein pressure, and low plasma albumin in liver failure can cause edema. 4. Malnutrition edema.

5. Localized lower limb edema. It is mostly caused by obstruction of the veins and lymphatic vessels in the lower limbs, resulting in the entry of body fluids into the tissue spaces. It may be caused by thrombophlebitis of the lower limbs, lymphangitis, filariasis, or compression of the veins by pelvic or lower limb tumors. It can be seen that there are many reasons for leg swelling. It can be a symptom of systemic disease or a symptom of local disease in the lower limbs. Therefore, you must go to the hospital for a comprehensive examination to find out the cause before you can carry out reasonable treatment.
