I am gluten intolerant and I keep having terrible stomach pains, please help!?

It seems to me like you really need to see a dietitian or doctor. The advice I would give would be to increase your calorific intake, as 2000 is the recommended number a day, and also regulate how much fibre you eat - too much can cause stomach aches. It could also be possible that you have I.B.S., or irritable bowel syndrome, which would need to be seen and treated by a doctor. There are many possible answers, and I think that only a doctor can give you the best advice.
