The most common cause of stomachache is ulcers in the stomach and intestines. According to the symptoms and location of ulcer, it can be divided into gastric ulcer and duodenal ulcer. Stomach pain before meals is mostly peptic or duodenal ulcer, and stomach pain after meals may be gastritis. When gastric ulcer occurs, gastric juice secretion becomes vigorous. If there is no food in the stomach for gastric juice to digest, it will corrode the stomach wall and produce a feeling of pain. If this situation is left unchecked, there will be holes in the stomach wall eroded by gastric juice over time. There is a simple way to check gastric ulcer: lie prone and let others help you press the nests on both sides of your ass. This part is called "Onodera tender point". If there is pain, it is gastric ulcer. Instead, thank you for your stomachache after dinner. It may be gastritis. Gastric ulcer is certainly not painless after meals, but it is not as obvious as gastritis. Gastritis and gastric ulcer are two major diseases of the stomach, which are closely related to the usual eating habits. Overeating, irregular life, staying up late, depression, excessive alcohol and tobacco will all lead to stomach problems. Eating irritating foods, such as peppers and peppers, sometimes causes stomachache. Intestinal syndrome can also cause stomach pain. Its characteristic is that the pain may be relieved when going to the bathroom to take a bath, but the pain will recur. Food poisoning is another cause of stomachache. You may eat chicken in the refrigerator for a few days, and your intestines will protest. Gas can also cause stomachache. When you digest food, a lot of gas will accumulate in your stomach, such as methane produced by bean digestion, which will also damage your digestive system and cause discomfort until it is released by burping or farting. In addition, many digestive system diseases can also cause sudden severe abdominal pain. ? If you have obvious and severe abdominal pain, you need to see a doctor immediately. Strong recurrent stomachache is a very serious disease and should be treated with drugs. But for slight temporary abdominal discomfort, you can try the following methods. 1, relax: Now some studies show that bad mood is closely related to gastric mucosal disorder. If you have gastritis, you are in a bad mood, which will affect the repair of gastric mucosa. So when you have a stomachache, relax and don't be too nervous. 2. Try antacids: Almost all over-the-counter antacids can well neutralize excessive stomach acid. 3. Taking antibiotics: Because the main cause of gastric ulcer is the infection of Helicobacter pylori, antibiotics are used for sterilization. Commonly used antibiotics include omeprazole, amoxicillin and metronidazole. 4. Avoid using too much aspirin: because salicylic acid, the active ingredient, will wear the inner layer of the stomach, which will lead to gastric bleeding. If you take 2-3 aspirin because of a cold or headache, that's enough. But if it is used as a daily necessity for more than three months, there will be problems. Ask your doctor or pharmacist to recommend some alternative medicines that won't irritate your stomach. 5, supplement nutrients: gastric ulcer will lead to the loss or absorption of certain nutrients, need to be supplemented.
