When symptoms of right abdominal pain occur and the cause needs to be identified, appropriate tests, such as ultrasound and CT, need to be performed under the supervision of a doctor. Right abdominal pain may be physiologic or pathologic. Physiological causes do not need to be dealt with or need to be relieved by adjusting the lifestyle. Pathological causes are due to diseases, which may be appendicitis, liver abscess, cholangitis, cholecystitis, kidney stones, gynecological problems, gastrointestinal diseases, etc. Generally, it is necessary to do the following examinations. 1. Diseases with common right abdominal pain such as liver abscess, cholangitis, cholecystitis, kidney stones and appendicitis require color Kepler ultrasound and routine blood tests. If necessary, abdominal CT or MRI should be performed. 2. Especially for women, when pain occurs in the right abdomen, abdominal ultrasound can be done first to check for gynecological diseases. 3. Gastrointestinal diseases can usually be examined by endoscopy, such as gastroscopy and enteroscopy. When pain occurs in the abdomen, you must pay attention to observation and go to the regular hospital for examination and treatment in time.
