** 1. since possibility of tumor is ruled out, thus primary aldosteronism is ruled out, and as your history suggests excessive production thus secondary causes of increased aldosterone like congestive cardiac failure [CCF], renal edema, and cirrhosis of liver which causes edema in body are likely possibilities to rule out with specific examination and Investigations. [Abdominal CT scan, chest X-ray, echocardiogram, plasma aldosterone level and renin activity, serum potassium level, Urinary aldosterone level]. 2. I will not recommend any medicines,but treatment will depend after the likely cause is diagnosed and then management is initiated.
