Sometimes referred to as: celiac sprue, celiac disease, coeliac, gluten intolerance, gluten allergy
Celiac disease, also known as gluten intolerance, is inflammation of the small intestine caused by exposure to gliadin—a component of gluten, which is a protein found in wheat, barley, rye, and (to a lesser extent) oats. (Oats do not contain gluten by nature, but they can become contaminated in facilities that process the other grains.)
1 in 133 people, or approximately 3 million Americans, currently have celiac disease.
Celiac disease is 2-3 times more common in women than in men.
Varies depending on sensitivity.
The average age of diagnosis in the US is about 40, though there is a peak around age six and another in the fourth and fifth decades. Celiac can show up in genetically predisposed children once the environmental trigger (exposure to gluten) has occurred, so historically it was considered more of a childhood disease.
Celiac also presents differently depending on age. In children, diagnosis may be pursued due to diarrhea, malnutrition, failure to gain weight, or delayed puberty. Adults more commonly find out during a workup for IBS, or possibly through investigation into reasons for anemia or low bone density. Age of diagnosis has shifted to include more older adults, and there is increased awareness that symptomatology can vary.
Recurrent or chronic diarrhea, abdominal pain, bloating, foul-smelling stools, and constipation are the most common gastrointestinal symptoms.
No, they can also have what we call extraintestinal symptoms (symptoms beyond the intestines). Sometimes people present with a characteristic rash, joint pains, or even a routine blood test revealing elevated liver enzymes—all these symptoms are more common in adults.
Most people do have GI symptoms, but the spectrum of severity is relatively broad. Around 60-70% of those who have celiac are undiagnosed, likely because celiac can have these non-GI presentations—like fatigue or coordination and balance problems.
