[wronged]

I am a 21 y.o female. I am 5'9, 130lbs. My diet is mainly healthy.For many yrs now i have experienced serious bloating after meals, particularly after eating fruit,dairy and carbs (complex or refined,no matter). When i relax or push out my stomach after such a meal i look pregnant (it is completely flat when i have an empty stomach). I get very gassy. I then get either constipated or diahrrea,depending on the kinds of food i have eaten. I do not feel nauseous at all. My stomach does weird spasms pretty often.While this can all be pretty uncomfortable I was wondering if it is common and not indicative of a digestive disorder or maybe something else?any informed answers appreciated,thanks ------
