Hey there Mish. Good to hear you have a colonoscopy scheduled - that should give you some answers. Your symptoms of gas, bloating, pain, and diarrhea are hallmark symptoms of IBS, but they can also be attributed to other disorders. Where exactly is your pain? How often are you having diarrhea? You can be as descript
ive as you want...we've heard it ALL before.
And congratulations on your decision to embark on recovery for your eating disorder. That's a huge thing! Can I ask what kind of eating disorder you've been dealing with? That could give some clues about what's going on in your digestive system. I assume your weight loss was purposeful, and if you had the help of a nutritionist, it was probably done healthfully.
There are some great peeps on this board who can give you loads of info. Some advice you might hear: start keeping a meticulous food and symptoms diary. Also list any medications that you take and the effects they have. This will be very beneficial for your GI doc.
Diagnosing GI problems can take a LOT of time and can be a frustrating process...we sympathize completely.
