Hello, all. First, a bit of background.

I'm a 15-year-old male. I've been suffering from diarrhoea and severe stomach pains for the past year. I saw a gastro and had a colonoscopy and it was determined that I had colitis. I was then prescribed to take Asacol, which was supposed to reduce flare-ups. After being on the medication for months and months, nothing changed.

After the medication wasn't working I had some blood work done, and the test came back negative for Celiac.

For the past year, I've grown a lot but haven't gained any weight. I have found it impossible to gain any weight at all, even with a huge appetite. Right now, my BMI is at 14.5, which is dangerously low. I'm also finding that I'm randomly weak sometimes when exercising.

Is it possible that I do, in fact, have Celiac. Would it be a good idea to try the gluten-free diet to see if it helps?
