Stomach pain may be caused by digestive diseases, drug stimulation, improper diet and other reasons. 1. Gastrointestinal diseases: Stomach pain can occur for a short time due to acute gastritis, gastric bleeding and other diseases. Some patients can have violent vomiting after the pain, which leads to cardia tearing and increased stomach pain. 2. Stimulation of drugs: due to long-term use of anti-inflammatory drugs, such as ibuprofen extended-release capsules, aspirin enteric-coated tablets and other drugs, may cause damage to the gastric mucosa, the formation of ulcers caused by stomach pain. 3. Improper diet: Stomach pain occurs due to stimulation of the gastric mucosa by prolonged high-intensity work, disorganized rhythm of life, irregular diet, and prolonged consumption of alcohol. When the stomach pain is serious, it is recommended that the patient should go to the hospital in a timely manner, under the guidance of the doctor to carry out relevant examinations, to clarify the cause of the disease, and then carry out relevant treatment.
