Dr. Hanif warmly welcomes you! Thanks for consulting at my virtual clinic. I have carefully worked through your case, and can realize your health worries. Being your physician, I want to assure, I will take care all of your medical concerns. You have not given any symptoms of how it came to your knowledge that you are retaining water. If you have legs, feet and ankle swelling (peripheral edema), then you should talk to your doctor. If I was your treating physician, I would have changed your medicine to Hydrochlorothiazide 12.5mg 1 tablet/capsule daily taken by mouth and continued on. You are classified as prehypertensive right now. Ans if you are obese, have strong family history of high blood pressure or cardiac diseases, then you may enter a higher level of Hypertension if left untreated and that is stage 1. Yes, you typically need medicine right away to save your heart, lungs, kidneys, brain and other organs from damage which takes a couple of years in most patients with hypertension. If you are obese, 10 pounds of weight reduction will take your blood pressure to 130/81 or so and that is quite near the normal range. In this way you may leave medications. If smoker?? Leave smoking. Its hazardous for you. Hope I answered all of your questions.
