Course Description

Celiac disease is a serious autoimmune disorder affecting approximately one in 100 people around the world. At least three million Americans are living with celiac disease, and 97% of them are undiagnosed.1 Celiac disease often goes undiagnosed because many of its symptoms are nonspecific, meaning that the same symptoms for the disease are common in various other disorders. Often undiagnosed and unaware, the people affected by celiac disease may be causing further damage to their bodies with every meal they eat. People with celiac disease must avoid gluten, a mixture of proteins found in many grains and products made from those grains.

Left untreated, celiac disease can result in serious systemic complications by damaging the small intestine and reducing its ability to absorb nutrients. Over time, the damage may escalate to skin rashes, lactose intolerance, infertility, bone weakness, and nerve damage.

Recognition of the oral manifestations of celiac disease may be key to discovering this devastating disease in patients where symptoms are less evident. In this course, learners will become familiar with the various oral signs and symptoms that may indicate this serious systemic illness may be underlying. Helping patients understand that they may have gluten-related disorders could be the key to a lifetime of improved health.
