If you're not comfortable doing that, at least check reputable web sites like drugs.com, webmd.com, mayoclinic.com. Google quitting... Source: over 3 years ago

Here https://emedicine.medscape.com/article/171805-overview#a2, under Epidemiology, they note a four-fold increase in all-cause mortality among people with undiagnosed celiac disease.
