Twelve ulcers, hemorrhoids and bleeding of the upper digestive system. Elevated gastric secretions, inflammation, swelling of the veins at the end of the rectum

The most important cause of bleeding in the upper digestive tract is the duodenal ulcer. Many researchers believe that these ulcers due to high secretions of the stomach and inflammation of a particular type of bacteria known as (Helicobacter Pylori). In the lower gastrointestinal tract (colon and rectum), hemorrhoids are the most common causes of haemorrhage. Hemorrhoids are the swelling of the veins at the end of the rectum and these veins bleed due to the high pressure in these veins. Doctors are interested in screening these patients to make sure there are no other causes of bleeding.
