Swollen feet in older men may be due to heart insufficiency and heart failure, which leads to decreased ejection of blood from the body, which then increases the body’s tissue fluid. Since the foot is in the lowest position of the body, when an elderly male develops swollen feet, check the heart first. If the heart is failing, controlling it with aggressive medication can facilitate blood circulation and reduce the amount of tissue fluid, allowing the swollen feet to be relieved. Some patients have swollen feet due to liver insufficiency or kidney insufficiency, and again, liver and kidney function tests and ultrasound are needed to detect the specific cause. It may also be due to varicose veins caused by venous valve insufficiency, or due to deep vein thrombosis, which causes obstruction of venous blood flow. A detailed examination by a professional doctor is needed to find out the specific cause of the problem and to provide symptomatic treatment.
