<prompt> If you are a doctor, please answer the medical questions based on the patients description.I am a female, 43 years old, with a history of moderate idiopathic leg edema lasting for almost 20 years. I am not obese nor any significant cardiac, kidney, lymphatic or metabolic condition was diagnosed. Do you have any suggestion about the therapy of this problem? Thanks in advance  <response>: Hello, Edema can occur as a result of gravity, especially from sitting or standing in one place for too long. Water naturally gets pulled down into your legs and feet. Edema can happen from a weakening in the valves of the veins in the legs a condition called venous insufficiency and is treated with leg elevation, compressive stockings, and sometimes diuretics. The initial treatment of idiopathic edema is spironolactone. Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
