(1) Obviously, there are gastrointestinal (GI), stomach, and digestive problems. These can include one or some of the following: Gas, bloating, queasiness, abdominal cramping, constipation, diarrhea, or an alternating combination of both - IBS (IrritableBowel Syndrome).
(2) Headaches and/or migraines.

(5) Neurological issues, including dizziness, difficulty balancing, and peripheral neuropathy affecting nerves outside the central nervous system and resulting in pain, weakness, tingling or numbness in the extremities.
(6) Fatigue, whether chronic or almost after every meal. Chronic fatigue syndrome (CFS) is, like fibromyalgia, a syndrome, not a disease. If that's what you're diagnosed with, it means your doctor can't locate the cause of your fatigue.

Traditional gluten intolerance blood testing looks for only one of six polypeptides in wheat, gliadin.
There are five others: wheat germ agglutinin, glteomorphin, gltueinin, prodynorphin, and omega gliadin. Any one or a combination of these five can cause anyone to have reactions to wheat.
