I had a minor stroke and I m recovering well. One thing is I have gained 16 lbs in 6 weeks. I have little to no appetite am eating mostly fruit and veggies, fish no carbs and maintaining a good exercise plan 30-45 minutes 4 times a week. Meds are aspirin,amlodipne, atorvastatin,carvedilol, losartan left foot mildly swells occasionally. What can be causing the extreme weight gain?
