Swollen feet in the elderly may be caused by physiological reasons such as excessive water intake, or by pathological reasons such as liver and kidney dysfunction, heart disease, and venous injury of the lower extremities.
1. Physiological reasons: If the elderly consume too much water or too much salt, it may cause swelling of the feet.
2. Pathological causes
(1) Renal dysfunction: If the elderly suffer from chronic nephritis and other diseases, resulting in impeded water excretion, causing water balance disorders and sodium retention, it may cause swelling of the feet.
(2) Liver dysfunction: If the elderly suffer from liver dysfunction such as cirrhosis, it may cause hypoproteinemia, etc., resulting in water excretion and swelling of the feet.
(3) Heart disease: if the patient suffers from right heart failure and other diseases, there will be symptoms related to body circulation stagnation, resulting in depressed edema of the feet.
(4) Lower extremity venous injury: If the patient has lower extremity venous thrombosis or lower extremity venous valve insufficiency, there can be lower extremity blood reflux obstacles, resulting in edema of the feet.
Swollen feet in the elderly may also be caused by other factors, the patient should go to the hospital as soon as possible for examination and consultation.
