whoa, you posted while I was posting and I didn't realize it! Sorry!
It sounds like your doctor is going to make you wait a little bit to do much more which stinks! I'd log exactly what you eat. I had a friend who ended up having a food intolerance (gluten) that was celiac disease. She had several issues from it. Another friend had severe issues if she ate corn or nuts leading to an eventual diagnosis of diverticulitis. Both helped aid in figuring it out by keeping a food journal each day leading up to seeing the doctor.
It can take a little time to bounce back from gastroenteritis but what kind of concerns me is the bloating. Is it hard to button your pants for example (or zip or whatever, lol)?
Hi! Do you mind if I ask your age? Any other health issues? I think you are doing the right thing by getting checked out. I'm wondering if the bloating is fluid build up like ascites? Different things can cause this type of bloating PLUS weight loss from gluten intolerance to things like pancreatic or ovarian cancer (do not worry until you have to worry!!) But your age would be helpful.
