Ileum

The ileum is the final section of the small intestine and is located between the jejunum and the caecum. It is responsible for the absorption of a majority of vitamins, minerals and nutrients from the food we eat and is a key organ in the digestive system. The ileum is also important for the production of certain hormones which regulate blood sugar and appetite. Malfunctions of the ileum can occur due to certain diseases such as Crohn's Disease, irritable bowel syndrome and ulcerative colitis. Treatment of these diseases typically includes lifestyle and dietary modifications, as well as medications (e.g., antibiotics, anti-inflammatory drugs, and immunosuppressants). Additionally, surgery may be necessary to remove parts of the ileum or to restore its function.
