It may be gastritis or digestive tract ulcer. It is best to do gastroscopy and abdominal B-ultrasound examination to see the liver, gallbladder and pancreas. It is now believed that stomach diseases are spread by Helicobacter pylori through the digestive tract. It is suggested to adopt quadruple therapy for gastritis under the guidance of local doctors: the most commonly used quadruple therapy is as follows: drug combination, dosage and usage: (1) bismuth potassium citrate 240mg+ amoxicillin 750mg+ metronidazole 400mg+ omeprazole 20mg or (2) bismuth potassium citrate 240mg+ erythromycin 500mg+ metronidazole 400mg+ omeprazole 20mg (3). Each drug is taken twice a day (1 time, in the morning and afternoon respectively), and 7~ 14 days is a course of treatment. After a course of treatment, continue to take potassium bismuth citrate alone for 6 weeks, with the same dosage and usage as before. Pay attention to the skin test of amoxicillin. This scheme can kill Helicobacter pylori and protect gastric mucosa. Insist on taking it to prevent recurrence. Smoking and drinking must be banned. Coffee is a spicy food. Eat less starchy foods, such as potato, taro, vermicelli, sweet potato and other jellies, do not eat soda biscuits, eat less and eat more meals, eat regularly, and do not eat foods that are too hard and difficult to digest. Here are some suggestions in daily life to help you prevent or relieve heartburn and gastritis: 1, don't overeat. If you eat too much, your stomach will be full, and stomach acid and food will easily flow back to your esophagus. 2. Eat less and eat more. Hunger can lead to the production of stomach acid. Eating less and eating more can avoid the feeling of excessive hunger, so it can reduce the production of gastric acid. 3. Control your weight. Excessive abdominal fat will cause pressure on the stomach, which is more likely to lead to gastroesophageal reflux. If you want to eat more meals, you must eat less per meal, so as to control the overall calorie intake. 4. Don't lie down for 60-90 minutes after meals. Imagine if your stomach is the bottom of a bottle full of acid, then the esophagus is the bottleneck. If the bottle is tilted, the liquid in it will flow out easily. Therefore, lying down just after eating is easy to cause acid reflux. When you lie down, keep your head high. Some people turn sour when they lie down, whether they have just eaten or not. In this case, the head should be raised when lying flat, or the head of the bed should be raised. 6. Eat less at night. To avoid hyperacidity caused by excessive hunger before going to bed, it is also correct to eat a small amount of midnight snack, but the amount must be controlled, otherwise it will easily lead to acid reflux and gain weight. 7. Avoid eating anything irritating to the stomach. Alcohol, aspirin and non-steroidal anti-inflammatory drugs such as ibuprofen (trade name) and naproxen (trade name) are the most common causes of gastritis. Some prescription painkillers and many over-the-counter drugs can cause stomach upset. Smoking also increases the risk of gastritis. 8. Understand the taboos in diet. Generally speaking, doctors advise people with a bad stomach to avoid eating foods that are easy to cause stomach acid, such as peppers, citrus fruits or carbonated drinks. In fact, most people will not have any adverse reactions to these foods, and caffeine will make many people feel uneasy. Generally speaking, patients with gastritis and gastroesophageal reflux should avoid foods that will aggravate pain. 9. Eat more broccoli. Cauliflower is a nearly perfect food, which has many benefits, one of which is that it can protect the intestines and defend against Helicobacter pylori, which causes most ulcers and some gastritis.
