In addition to the pain and other discomforts caused by gastric ulcers, a significant number of patients may experience complications as a result of untimely diagnosis and treatment. Complications can be life-threatening and far more serious than the ulcer itself. According to statistics, the incidence of complications accounts for more than 1/4 of the total number of gastric ulcer patients. Gastric ulcer has the following four major complications (1) ulcer bleeding bleeding is the most common complication, some statistics about 10 to 25% of ulcer patients bleeding, that is, hundreds of thousands of ulcer disease bleeding every year. Clinical manifestations are vomiting blood and/or black stools. Often the amount of blood loss of more than 1000 ml called hemorrhage, bleeding too fast and too much, can quickly lead to shock, or even death. (2) Perforated ulcer When the gastric ulcer becomes deeper and deeper and breaks through the outer plasma membrane layer of the gastric wall, the ulcer penetrates through the gastric wall and the gastric contents may flow into the abdominal cavity, which is called perforated ulcer. The perforated ulcer often produces severe abdominal pain, acute peritonitis, manifested as abdominal straightening, intestinal peristalsis weakened or even disappeared, the worst case of paralytic intestinal obstruction, septicemia and septicemia. (3) Pyloric obstruction About 10% of ulcer patients suffer from pyloric obstruction, gastric emptying obstruction, gastric retention, abdominal distension, followed by frequent vomiting. (4) Cancer of gastric ulcer As the gastric mucosa around gastric ulcer is repeatedly stimulated, it has been proved that some of them will develop cancer after a period of time, about 2%, which is often larger, and can be manifested as vomiting blood and black stool. At this time, patients often feel obvious, appearing weakness, panic, pallor, or even shock. Clinicians refer to gastric ulcers complicated by hemorrhage as blood loss of more than 1,000 milliliters within minutes or hours. Hemorrhage due to a large amount of blood from the blood, circulation loss, the body's normal physiological blood supply leads to insufficient, the heart, brain, kidneys and other important organs of the blood supply and oxygen supply is insufficient, resulting in dizziness, panic, urinary or no urine, such as not in time to fill up the blood volume, the person will be due to ischemia occurs in shock, shock can not be rescued on the order of death. For a small number of gastric ulcer patients usually may not have obvious discomfort symptoms, and bleeding is the only manifestation, often because of gastric bleeding before being diagnosed as gastric ulcer. Source www.maizangyao.com Gastric ulcer is a global epidemic, the study about its bleeding is very much each country statistics bleeding incidence varies, in our country had someone to 20,000, more than 5,000 cases of ulcer disease hospitalized patients statistics, hemorrhage accounted for 14-67%. Taken together, the incidence of hemorrhage in gastric ulcers ranges from 10 to 25%, and from this percentage we can see that the chances of bleeding from gastric ulcers are relatively high, and therefore, active prevention and treatment is of great significance. Doctors usually determine whether there is bleeding in the upper gastrointestinal tract by whether the color of the vomited blood is coffee-like or whether the stool is tarry. According to statistics in the cause of upper gastrointestinal hemorrhage, gastric ulcer and duodenal ulcer complication hemorrhage accounted for about 1/2, gastric ulcer hemorrhage rate is slightly lower than the duodenal ulcer hemorrhage.
