The ileocecal valve connects the small intestine with the large intestine. The small intestine takes in all of the nutrients (healthy substances) that the body needs. The large intestine absorbs moisture from the matter that is left, and excretes the waste from the anus. Food normally travels from the small intestine to the large intestine. The ileocecal valve prevents food from reentering the small intestine once it gets to the large intestine. In other words, it prevents the food from traveling backwards, from the large intestine to the small intestine. The ileocecal valve may become irritated in health conscious people who eat large amounts of foods that are high in dietary fiber. Dietary fiber is a term for chemical substances in the cells of plants that cannot be digested by the human body. As a result of the irritation to the ileocecal valve, it may not be able to function as effectively. Symptoms of ileocecal valve disorder are pain in the lower right part of the belly, feeling full after eating small amounts of food, and feeling bloated. Constipation (difficulty pooping), gas, and diarrhea (loose, watery feces) are also symptoms of ileocecal valve disorder. The previously mentioned symptoms can get worse after eating foods high in dietary fiber. Ileocecal valve disorder is usually treated by taking steps to decrease the irritation to the ileocecal valve. This can be done by decreasing the intake of foods that are high in dietary fiber. Other steps that can be taken include avoiding foods that have lots of spices, and avoiding scratchy foods such as grains and wheat bran. Avoiding foods that cause constipation, such as bananas and cheese can also be helpful. People should also avoid foods they are sensitive to.
