Crohns disease is an inflammatory condition of the digestive tract. The inflammation can be in the small intestine, the large intestine or at the anus. The normal function of the digestive tract – receiving food, digesting it and expelling the waste- will be affected by Crohns disease. so crohn’s disease symptoms are centred around the digestive tract. Diarrhea is one of the symptoms of Crohns disease. When the large intestine is swollen, it produces large quantities of fluid which comes out with the stool causing diarrhea. Constipation is another symptom. When there is inflammation at the anus, the stool desnt pass out easily and it leads to constipation. another symptom is anemia. When the number of red blood cells in the blood is less than than the required number, the ability of blood to carry oxygen to the body tissues is reduced. Deficiency of oxygen in the body cells is called anemia. Inflammation anywhere in the body or bleeding can lessen the number of red blood cells in blood. a patient suffering from Crohns disease will need to visit the toilet frequently. Persistent or occasional stomach pain is another symptom of Crohns disease. If the inflammation is in the smal intestine, the food doesn’t go down to the large intestine; rather it tries to come back to the stomach and mouth causing a feeling of vomiting/nausea. Inflammation of the small intestine also leads to malabsorption of nutrients from food and the result will be malnutrition. Fever and weight loss are other symptoms of Crohns disease.
