The symptoms of stomach pain can be targeted according to the causes of stomach pain, as follows: 1, spasmodic pain: if the pain is caused by intestinal spasm, you can use scopolamine, atropine, antispasmodic spirit and other drugs, which can relieve muscle spasms and convulsions, mainly for stomach pain caused by stomach spasm after eating raw and cold, stimulating food, and emotional tension; 2, stomach acid irritation pain: omeprazole, rabeprazole etc., can reduce the secretion of gastric acid, mainly for peptic ulcer, gastroesophageal reflux disease and other stomach pain brought about by increased gastric acid stimulation of the stomach; 3, pain after damage to the gastric mucosa: aluminum thioglycollate, colloidal bismuth and other drugs, can form a protective film in the gastric mucosa, effectively repairing the damaged gastric mucosa, which helps to relieve stomach pain caused by damage to the gastric mucosa, such as gastritis, stress gastric ulcer, etc.; 4, cancer pain: weak Opioids include tramadol, tramadol extended-release tablets, codeine, etc. Strong opioids include morphine, oxycodone hydrochloride, fentanyl, etc. They are generally used in more serious cases, such as stomach pain caused by gastric cancer, with good analgesic effect, but are prone to gastrointestinal adverse reactions, such as nausea, vomiting, etc., and are easy to produce dependence. Note: The simple application of analgesic drugs may mask the condition. Some patients with early stage of acute appendicitis, common bile duct stones and biliary tract infection, acute pancreatitis, gastrointestinal perforation can manifest as severe pain in the upper abdomen, which needs to be differentiated from stomach pain in time. When stomach pain occurs frequently or persists without relief, one should be alert to the presence of gastrointestinal perforation and seek medical attention promptly to avoid serious complications.
