Hello- for the past 3 months I have been taking amitiza for my ibs in combination with dulcolax. After months of not seeing results from other medications, this actually worked! I am no longer chronically constipated, and my doctors are considering dropping the dosage given my progress. HOWEVER in those 3 months, I have put on a significant amount of weight- about 12lbs. I began seeing a nutritionist for this issue, as it has been horrendous. I do not fit into any of my clothes and am completely devastated with myself. I am a very healthy person, I exercise and do strength training 5-6 times a week and eat around 1800 calories (5'2 female). This has been what I have always done and maintained a healthy weight. But that all went downhill since I began amitiza. I know many people do not experience weight gain as a side effect, but in a rare case is it possible? Do you believe my weight gain could be associated with taking amitiza every day?
