I'm not sure if I have IBS. I know that I have many of the symptoms. I cannot gain weight (i'm 5'3 i weigh about 99lbs). I have terrible gas. I only occasionally get constipation or diahrrea. I have a lot of anxiety. I also have abdominal pain. I have noticed the abdominal pain has lessened but my anxiety has increased over the years. I cut down on my carbs and dairy. That is the only real diet change I have made.So my question is does it just lessen on its own ever? Or does it get worse? Or is it different with everyone?
