Explanation:

An autoimmune disease can be described as a disease which occurs as a result of the body's own immune system destroying cells of the body.

Celiac disease is an autoimmune disorder in which the immune system attacks its own intestine whenever gluten-rich food is taken. As a result, serious damage is caused to the villi. As villi are structures involved in nutrient absorption, damage to them causes lack of nutrient absorption. This leads to malnutrition.
