I have been taking Losartin for about a year now and I have gained more weight in a year than ever. I think about 20 to 25 lbs and feel bloated after I eat, My fingers and hands get a tingling feeling like they are asleep when I just write some of use them in the kitchen. I still exercise several times weekly and I still eat well, no junk food so my diet hasn't changed. I have even tried to diet and really watch what I eat and I don't lose. Could this medicine be the source of my weight gain?
