Greetings, thank you for the question. This answer is a general explaination of the problem you encountered. Please click on this link (DoctorOnCall) to talk to a doctor.

Leg swelling can caused by the retention of fluid in leg tissues and known as peripheral edema. It can be caused by a problem with the circulatory system, the lymphatic system or the kidneys.

Leg swelling isn’t always a sign of a heart or circulation problem. You may often experience swelling due to fluid buildup from being overweight, being inactive, after sitting or standing for a long time, or wearing tight stockings.

Factors related to fluid buildup include:

• Acute kidney failure
• Cardiomyopathy
• Chronic kidney disease
• Cirrhosis
• Deep vein thrombosis
• Heart failure
• Hormone therapy
• Lymphedema

I suggest you to bring your father to hospital for further investigation to avoid deteriorating his health condition.
