			'''Autoimmune enteropathy''' is a rare [[autoimmune disease]] characterized by severe and chronic [[diarrhea]] resulting from immune system dysfunction targeting the [[intestine]]s, leading to the destruction of the intestinal lining. This condition is most commonly diagnosed in infants and young children, but it can also affect adults.

	==Symptoms and Diagnosis==		==Symptoms and Diagnosis==
	The primary symptom of autoimmune enteropathy is persistent diarrhea, which is often watery and may be accompanied by [[malabsorption]] of nutrients, leading to [[weight loss]], [[malnutrition]], and failure to thrive in children. Other symptoms may include abdominal pain, cramping, and bloating. Due to the malabsorption of nutrients, individuals may also suffer from deficiencies in vitamins and minerals, which can lead to further health complications.

Due to the malabsorption of nutrients, individuals may also suffer from deficiencies in vitamins and minerals, which can lead to further health complications.

	Diagnosis of autoimmune enteropathy involves a combination of clinical evaluation, laboratory tests, and imaging studies. Blood tests may reveal signs of anemia or abnormal levels of nutrients. [[Antibody]] tests, specifically anti-enterocyte antibodies, can support the diagnosis. The most definitive diagnostic tool is a biopsy of the small intestine, which typically shows damage to the intestinal lining and loss of villi, the tiny finger-like projections that absorb nutrients.

	==Treatment==		==Treatment==
	Treatment of autoimmune enteropathy focuses on managing symptoms and preventing further damage to the intestines. The mainstay of treatment includes immunosuppressive medications, such as [[corticosteroids]], [[cyclosporine]], or other drugs that reduce the immune system's activity. Nutritional support is also critical, and may involve the use of special diets, [[vitamin]] and [[mineral supplements]], and in severe cases, parenteral nutrition (feeding a person intravenously).
