9. Celiac Disease
This disease causes individuals to suffer from inflammation within their intestine, due to a hypersensitivity to gluten. This autoimmune disorder can actually cause damage, resulting in abnormal absorption of nutrients. There’s a lot of confusion surrounding this disease, resulting in many individuals remaining undiagnosed.
In fact, on average, it takes approximately six to ten years to be accurately diagnosed. If you believe that you may have celiac disease, request a blood test. If you do in fact have this condition, an endoscopy can then be used to determine whether or not damage has occurred.
