Normally, it is the function of the colon to store waste material until most of the fluids have been removed to enable well-formed soft stools, consisting of non-absorbable food materials to be passed. People who suffer from an irritable colon have irregular and erratic contractions which are specifically noticeable on the left side.
All this loss of blood and fluid from the bowels results in weakness, fever, nausea, vomiting, loss of appetite and anemia.
The patient may develop a bloated feeling because the gas is not absorbed or expelled normally. Some patients suffer from constipation alternating with period of loose bowel movements. Still others may suffer from persistent diarrhea for years together. The patient is usually malnourished and may be severely underweight. They may suffer from frequent insomnia. Ulcerative colitis in its severe form may also lead to nutritional problems. The improper assimilation of the ingested foods due to inflammatory conditions may cause deficiency diseases. This may gradually result in nervous irritability, exhaustion, and depression. In very severe cases, the patient may even develop suicidal tendencies.
Severe stress may produce ulcerative colitis. During any form of severe stress, an outpouring of adrenal hormones causes such destruction of body protein that at times parts of the walls lining the intestines are literally eaten away. Such stress also depletes the body of pantothenic acid. Experiments on animals have shown that they can develop ulcerative colitis when they are kept on diets deficient in pantothenic acid.
