“The craniofacial morphology of patients with celiac disease reveals an altered pattern of craniofacial growth,” claims an article titled ”Large Forehead: A Novel Sign of Undiagnosed Celiac Disease,“ in a 2005 issue of Digestive and Liver Disease.

Specifically, the study found that people who suffer from gluten intolerance had a larger forehead due to abnormal growth patterns as a child. To determine if this is a factor for you, measure from the bottom of your chin to the bottom of your nose, from the bottom of your nose to between your eyebrows, and from between your eyebrows to the top of your forehead.

The face should be divided into equal thirds; if your forehead is larger than the other two sections, there’s a good chance that gluten is affecting your gastrointestinal condition. Furthermore, a 2009 Polish scientific article states that one of five IBS patients suffer from positive antibodies to gluten!

Whether you have a large forehead or not, if you suffer from digestive irritability, there are many possible causes and treatment options that can greatly improve your life.
