Q:
A: Gluten is a protein found in wheat, barley, and rye. It's that thing that helps dough rise, making your bagels chewy and your sandwich bread soft.

Gluten can set off a range of negative responses in some people's immune systems. An extreme example is celiac disease. Normally we have tiny, hair-like projections (villi) that line the small intestine like a plush carpet, absorbing vitamins, minerals and other nutrients from food. But according to the Mayo Clinic's website, celiac disease makes the inner surface of the small intestine appear more like a tile floor.
“Celiac disease sufferers have a full fledged natural auto-immunity to the protein gluten. The gluten does not react to them directly,” said Eric Sieden, director of nutrition and food services at Plainview Hospital. “What ends up happening to people with celiac disease is that the body will react to the gluten by having the white blood cells attack the intestinal wall causing inflammation and loss of nutrient absorption.”
“Most symptoms are GI (gastrointestinal) in nature, such as nausea, vomiting, abdominal pain/bloating, diarrhea or constipation, lactose intolerance, weight loss from malabsorption or above symptoms,” explained Kelly O'Connor, a dietician and certified diabetes educator with Mercy Medical Center. “Also, other non-GI symptoms may occur, such as migraines, bone/joint pain, mouth ulcers, chronic fatigue, etc.”

Q:
A: It's hard to define, exactly.
“A gluten intolerance/allergy/sensitivity works differently with the immune system where the gluten protein itself causes the body to attack itself through inflammation in the small intestine,” explained Sieden. The body starts to beat itself up, even though it's aiming for the gluten.
Although it differs from celiac disease, experts can't exactly nail down sensitivity/intolerance as a definable problem.
“Some researchers have labeled the intolerance/sensitivity as NCGS (non-Celiac Gluten Sensitivity). Though this is a label that researchers have put on it, physicians have not been so quick to define it as a medical condition,” said Sieden. “The reason for this is that there is no defined medical test for it.”
For celiac disease, patients undergo a biopsy in order to determine a diagnosis. There's not much doctors can do in order to test for gluten sensitivity.
Additionally, these “gluten sensitivities” might belong to a broader family of wheat-related problems. More specific tests are being developed in hopes of cutting out the “constituents of grains that make them ill.”
Q:
Different people will display different side effects of celiac disease, but the most common symptoms are digestive issues like abdominal pain, diarrhea, and weight loss. Not everyone will show those symptoms, however; additionally, children could also show different signs of the disease. You could also suffer from fatigue, headaches, constipation, acid reflux, and other problems. The Mayo Clinic suggests to schedule a visit with your doctor “if you have diarrhea or digestive discomfort that lasts for more than two weeks.”
