I wondered if anyone else has had gastro problems with Metformin use in the long term. I know that it is well known to cause issues in the first few weeks of use but I am several months down the line (started tablets in July) and problems have just been going on for the past couple of months. Symptoms have been bloating, very gassy, burping, IBS type stuff. My GP has ordered a pelvic and abdominal scan (next week), FIT test and full blood tests which came back fine. He seems very on the ball to rule out anything sinister but I am now wondering if it's the Metformin causing the issues.
