Hi all, 37 yr old female, healthy overall, no meds apart from 20mg of LEXAPRO. I have gained about 30 lbs without real cause, and I cannot lose the weight despite good old eating healthfully and exercise. I mean walking 4 miles per day. Recent CBC showed no thyroid issues, sugar is ok, etc. What could it be? Doc thinks Lexapro made me gain, could it also be the reason I can't lose?? Thank you!
