Every time we have sex, my girlfriend gets severe gas pains! why? she's 41 & has not had any kids. she used to be overweight before her gastric bypass!

I : I am concerned because what she is perceiving as gas pains may actually be pelvic pain. First, i recommend she see her general practioner or gynceologist for a complete history, pelvic exam, and whatever diagnostic test that is deemed necessary. On the other hand, if she eats certain types of food prior to intercourse that cause gas, this could be the issue. There are too many foods to list, this will require some investigating on her part. Regardless she should have this issue addressed by a medical professional. I wish her well.

Gas pains: It might be coincidental in relation to happening after intercourse. However, gastric bypass patients can get bacterial overgrowth which can cause gas pains, excessive gas production, and foul smelling gas. She can get a simple breath test to determine if she has it. Treatment is fairly simple. Sometimes just taking probiotics can help. Other times it requires rifaximin.
