Document Summary
A hernia is a protrusion of a viscus through an abnormal opening or a weakened area in the wall of the cavity in which it is normally contained. If the hernia becomes strangulated, the patient will experience severe pain and symptoms of a bowel obstruction, such as vomiting, cramping abdominal pain, and distention. Malabsorption results from impaired absorption of fats, carbohydrates, proteins, minerals, and vitamins. Causes of malabsorption include the following: biochemical or enzyme deficiencies, bacterial proliferation, disruption of small intestine mucosa, disturbed lymphatic and vascular circulation, surface area loss. Three factors necessary for the development of celiac disease (gluten intolerance) are genetic predisposition, gluten ingestion, and an immune-mediated response. Early diagnosis and treatment of celiac disease can prevent complications such as cancer (e. g. , intestinal lymphoma), osteoporosis, and possibly other autoimmune diseases. Celiac disease is treated with lifelong avoidance of dietary gluten. Wheat, barley, oats, and rye products must be avoided.
