Abdominal pain is a fairly common clinical symptom, and abdominal pain is divided into two types: sharp pain and dull pain, while vague pain in the stomach belongs to dull pain, mostly caused by pain in organs or internal organs. The cause of dull pain is commonly caused by chronic gastrointestinal diseases, such as chronic gastritis or chronic enteritis, which can be examined by gastroscopy or colonoscopy in hospital, and pay more attention to diet, less cold, greasy and hard, and pay attention to dietary hygiene; there may also be abdominal pain caused by intestinal obstruction or intestinal parasites. If men have vague pain in the left lower abdomen, it may be caused by varicocele on the left side, so it is recommended to go to the hospital for examination and cooperate with the doctor for treatment. If a woman has vague pain in the lower abdomen, consider pelvic inflammatory disease or adnexitis, you can do abdominal ultrasound and gynecological double examination to find the cause and treat it. If a woman has vague abdominal pain during pregnancy, it may be physiological abdominal pain (due to the enlarged uterus and tight skin, which can cause abdominal pulling pain after exercise). In conclusion, for patients with vague abdominal pain, first of all, we should go to the hospital for examination and clear diagnosis and then actively treat the symptoms, and secondly, we should adjust our diet to avoid spicy stimulation and avoid raw and cold.
