Help please? i want to know what are symptoms of gluten intolerance in teens?

Gluten Intolerance: Teens with gluten intolerance can present with stomach upset, poor eating habits and poor growth or school performance depending on their overall nutrition. It is important to get evaluated with a simple blood test to determine if someone has this so their diet can be managed well.

Gluten: Some symptoms can be abdominal pain, vomiting, diarrhea; but sometimes no symptoms appear in the age and the child doesn't grow well which can be the first important clue. I just had a 7 year old last week that didn't grow or gain any weight from the previous checkup and ended up with celiac's (awaiting confirmation from a endoscopy) based on blood results.
