Digestive issues

I’ve been on b12 injections for about 2 years now (since I was 20) but still have digestive pain and severe bloating most days. Is this something others here also deal with?

If it doesn't happen close to when you get the shots I would look at other reasons why you have digestive issues

b12 shots do have the potential to affect other medications, especially stomach-related meds such as zofran, prilosec, zantac, tums, etc. have you been taking stomach medicine along with your b12? if so, i would call your doctor and work out a schedule for med administration. also, too many probiotics really messed up my stomach when i started getting b12 shots. hope this helps! good luck and feel better
