Stopping metformin and constipation
avatar
An_243543 posted:
I was on metformin for a few months because my doctor felt it might help with my weight. I am not diabetic though and it was making me sick especially a lot of stomach problems (diarrhea). The day after stopping it I became extremely constipated and in a lot of abdominal pain. Because of the constipation I am also peeing a lot. I went to the ER where they said nothing else was wrong with me except some swollen lymph nodes in my lower right stomach. Has anyone else experienced constipation after coming off metformin? It has been 3 weeks now since I have been off it and I am still feeling horrible. Any advice would be greatly appreciated. Thank you

Metformin has been linked to B12 deficiencies (it blocks B12 absorption in some people). B12 deficiencies can result in a whole host of health problems including constipation. Since the first rule of thumb is to do no harm, the first step is to check with your physician to see what he/she recommends. If the answer you receive has failed to resolve your problem, try supplementing with a sublingual form of B12 (methylcobalamin) because of its superior absorption. Dosage is one tablet dissolved under the tongue up to three times a day. B12 is a water-soluble vitamin and any excess will be excreted in the urine so there's virtually no risk of an overdose. Then add a good fiber supplement to your diet that includes insoluble fiber such as Metamucil. You should probably try taking the latter at least twice a day with meals. Hope this helps resolve your problem.
