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.
