This list is from dummies.com and I thought it was a pretty decent representation of some of the symptoms that could possibly occur.  If you find you have quite a few on this list (like I did) perhaps you should talk to your doctor!

There are 200-300 symptoms of gluten intolerance, so this is just a few of them:

Gastrointestinal symptoms: These are some of the “classic” — although not the most common — symptoms:

• Abdominal pain and distension
• Acid reflux
• Bloating
• Constipation
• Diarrhea
• Gas and flatulence
• Greasy, foul-smelling, floating stools
• Nausea
• Vomiting
• Weight loss or weight gain

Nongastrointestinal symptoms: Interestingly, although gluten sensitivity and celiac disease affect the gut, most people’s symptoms are not gastrointestinal in nature.
