2. Abdominal Bloating

Celiac patients also complain of bloating and abdominal fullness. This is another by-product of the impaired digestive process. Impaired digestion leads to the buildup of gases and fluid, mostly in the small intestines. The abdominal pressure thus produced may also cause cramping, pain, and in some cases, nausea. Many people attempt to use over-the-counter medications to alleviate these symptoms, but this is only a stop-gap measure.
