Gluten intolerance, also known as non-celiac gluten sensitivity, is a common condition that affects millions of people around the world. This condition is characterized by an adverse reaction to gluten. Gluten is a type of protein that is primarily found in rye, barley, and wheat.
There are two forms of gluten intolerance, celiac disease, and non-celiac gluten sensitivity. Between the two, celiac disease is more severe. However, non-celiac gluten sensitivity can trigger milder widespread symptoms which allow the condition to lay under the radar. In fact, non-celiac gluten sensitivity has been associated to fibromyalgia and many of its symptoms overlap with the chronic pain syndrome. One study found that a strict gluten-free diet helped 36% of its participants improve their fibromyalgia to the extent of remission. The study also suggested non-celiac gluten sensitivity to be a trigger of fibromyalgia.
