Autoimmune diseases occur when the immune system misfires and the body actually starts attacking itself.
Some of the common autoimmune digestive system disorders are:

 

Celiac disease – when a person becomes intolerant towards gluten, a protein found in wheat, barley or rye, resulting in digestive discomforts like diarrhea, vomiting, and abdominal pain.

 

Crohn’s disease – this condition occurs when the immune system attacks parts of the digestive tract, causing inflammation and swelling, causing abdominal pain, diarrhea, and fatigue. Some patients may also experience rectal bleeding.

 

Autoimmune hepatitis – Unlike most types of hepatitis, which are caused by viruses, autoimmune hepatitis happens when the body’s immune system attacks liver cells, causing inflammation.
