Recently, the temperature has dropped sharply. After the human body is stimulated by cold air, the secretion of gastric acid will increase greatly, the gastrointestinal spasmodic contraction will occur, and the resistance will be reduced. Therefore, the human gastrointestinal system is prone to dysfunction, and many people often have gastrointestinal problems. Wang Yanrong, director of the digestive department of the fourth central hospital, reminded the general public to be vigilant against gastrointestinal multiple diseases in winter. Director Wang Yanrong introduced that since October, patients with gastrointestinal bleeding have been hospitalized in the Department of Gastroenterology of the hospital every day. More than 80% of them are bleeding caused by peptic ulcer. Peptic ulcer is a chronic ulcer that occurs in the stomach and duodenum. The common clinical manifestations are upper abdominal pain, abdominal distension, nausea, vomiting, acid reflux, belching, etc. To prevent peptic ulcer, first of all, we should develop regular eating habits and reduce the intake of stimulating diet. Develop the habit of eating breakfast, eat less spicy food, drink less, strong coffee, strong tea, etc. Secondly, don't abuse drugs. Some antipyretic and analgesic drugs, such as Qutong tablets, ibuprofen and aspirin, can induce peptic ulcer or aggravate the condition, or even bleeding. Thirdly, keep the law of life and feel comfortable. People who stay up late, are nervous and anxious are easy to suffer from ulcer disease, so maintaining a good attitude and life law is also conducive to the prevention of peptic ulcer. Finally, the eradication of Helicobacter pylori is conducive to the prevention of ulcer disease. In addition, we should also pay attention to the prevention of gastrolithiasis in winter. Persimmon, hawthorn and black jujube contain a lot of pectin and tannin. If you eat these things on an empty stomach or after drinking, it is easy to form stomach stones under the action of gastric acid. Large and rough stomach stones can cause epigastric fullness, nausea, vomiting and epigastric pain. Some patients have symptoms similar to chronic gastritis, such as loss of appetite, dyspepsia, abdominal distention, dull pain, acid reflux, heartburn, serious complications, ulcers, bleeding, perforation, obstruction, etc., of which ulcers are the most common, A few patients showed paroxysmal pain under the xiphoid process or severe pain in the chest. If you have abdominal discomfort after eating persimmon, hawthorn and black jujube, you should go to the hospital for gastroscopy as soon as possible. For diseases affecting gastrointestinal emptying (peptic ulcer, constipation, etc.), it is best not to eat the above foods, and avoid eating milk, sweet potato, coffee and seafood at the same time.
