I've been using Nexium for nearly 2 months and have had amazing results, the one thing I have noticed is that I have put on about 7lb and I'm struggling to lose the excess weight. I do have Hypothyroidism but that is totally under control with thyroxine and have never had this problem before the Nexium. I exercise 3 times a week, and stick to a low fat diet so the only thing I can think of is the medication. Has anyone else experienced weight gain whilst taking Nexium? If so, how did you manage your weight gain?
