I was wondering if it's possible for metformin to cause severe food sensitivities and colitis. I am a 36 year old female with polycystic ovarian syndrome. After initiating metformin, many of the hormonal problems, including weight gain despite daily exercise and healthy eating habits, have greatly improved. However, several months after achieving a dose of 1250 mg of the metformin ER, I am experiencing profound food sensitivity and allergies that have been further complicated by colitis, vitamin D deficiency, fatigue, and chronic hives. The fatigue seems to persist despite vitamin D supplementation. I've had so much improvement in my condition since taking the metformin that I would be very disappointed if I had to stop it. I was hoping someone might be able to tell me if they have experienced food sensitivity and severe gastrointestinal problems on the metformin, and if these symptoms can be dose dependent. If it is the metformin, I was hoping I could tolerate a lower dose rather than stop it entirely.
Thanks so much for any info.
