Your digestive system is a hard-working machine. The energy it takes to break down food and assimilate it into -- and out of -- your system is often taken for granted, until something goes wrong. And that's just the case when it comes to celiac disease, a recipe for digestive disaster. Question is -- do you know the celiac disease symptoms? 

Believe it or not, there are actually hundreds of celiac symptoms associated with the condition. In fact, if you suspect you or your child might have the disease, see a doctor. Symptoms can differ widely among adults and children, and some sufferers exhibit no symptoms at all. 

According to the Celiac Disease Foundation, an estimated 3 million Americans suffer from this condition. WebMD describes the condition as "a digestive disorder that occurs in reaction to gluten, a protein found in rye, barley, wheat, and hundreds of foods made with these grains. The body's immune system reacts to the gluten and causes damage to the intestine."
