Q: “Is there a link between diet and fibromyalgia? I have been diagnosed with wheat and yeast allergies and have noticed that if I eat a lot of wheat my fibromyalgia symptoms flare up."

A: Gastroenterologist David Lloyd writes:
“There isn’t any conclusive evidence that diet either causes fibromyalgia or makes the condition worse.
Many people are sensitive to wheat, especially in highly refined products such as white bread. Eating these types of foods can cause a range of symptoms, from bloating and abdominal pain to muscle aches and general malaise. This is due to the way these foods are processed by the gut, rather than being a true allergy. However, with coeliac disease, a component of wheat and some grains causes intestinal inflammation. The symptoms are often vague and can include muscle pains similar to fibromyalgia. It would be worth asking your GP to check for coeliac disease by doing a specific blood test.”
