Flatulance symptoms and conditions

I have been on Metformin for 6-7 months 500mg 2 x daily, and have puffed up like a balloon with significant weight gain of at least 45lbs., no desire to do anything physical as I have no energy,stomach upset and increased bowel movements, flatulence and absolutely no sex drive. I am going to discuss this with my doctor but before I do in their any other medications other then Glipizide for type 2 diabetes? I keep putting on weight like I am my blood sugar will be way out of control.

gas, flatulence, bloating, all are a part of taking Welchol. I have to take it because it is the only relief I have found for IBS. My cholesterol is fine. Dr. put me on Welchol and I have (with help from stool softeners occasionally) been keeping in under control for the most part.

I have been on Yasmine for 3 months and I have experienced negative side effects such as constant flatulance, migraines, nausea, loss of appetite and fatigue. I am stopping and getting on seasonale.
