2. Celiac Disease
It is a form of autoimmune disease where the person is allergic to gluten, and eating gluten can severely damage their small intestine. When gluten is consumed by a person who has Celiac disease, their immune system reacts by damaging the small intestine. Gluten is a form of protein that is found in different food items such as wheat, barley, and rye.
Other than food items, gluten is also found in several vitamin supplements, medicines, lip balm, and glue stamps, as well. Celiac affects people differently. In some, it might not be a severe threat, while in others, it can develop into a life-threatening situation.
