Gluten is like a poison to people with celiac disease, because it damages their intestines. Gluten damages the intestines. This damage keeps your body from taking in many of the nutrients in the food you eat. This includes vitamins, calcium, protein, carbohydrates, fats and other important nutrients. Your body can't work well without these nutrients.
Celiac disease runs in the family.
You inherited the tendency to get this disease from your parents. If 1 member of your family has celiac disease, about 1 out of 10 other members of your family is likely to have it. You may have this tendency for a while without getting sick. A child could be irritable, fretful, emotionally withdrawn or excessively dependent. In later stages, a child may become malnourished, with or without vomiting and diarrhea.
