Typical causes of bowel diseases include hernias, tumors in the small intestine, inflammation of the intestines and abnormalities in the gastrointestinal nervous system, according to Mayo Clinic, Healthline and WebMD. Bowel diseases occur in different types, including irritable bowel syndrome, celiac disease and intestinal obstruction. Specific causes depend on the particular disease.
Irritable bowel syndrome affects the colon, causing abdominal pain, mucus in the stool, constipation and a bloated feeling. The cause of this condition is unknown. Doctors stress that a person with irritable bowel syndrome may experience a stronger wavelike muscle contraction in the digestive tract that lasts longer than normal, causing diarrhea and bloating. Abnormalities in the gastrointestinal nervous system can also cause discomfort when the abdomen stretches from stool or gas, notes Mayo Clinic.
Intestinal obstruction occurs when the intestines become blocked, preventing food from passing through the body. Typical causes include tumor formation within the intestines, hernias, twisting of the intestines and an inflammatory bowel disease such as Crohn’s disease. Symptoms include severe abdominal pain, constipation and the inability to pass gas, explains Healthline.
Celiac disease is an autoimmune and digestive disorder that damages the small intestine when a person eats foods that contain gluten. Immune system attack against the intestinal lining is the primary cause, damaging the villi and causing inflammation in the intestines, reports WebMD.
