If the patient has abdominal pain or other discomfort, it may be due to gastrointestinal disorders. If the patient is pregnant or has abnormal uterine pathology, such as uterine fibroids, adenomyosis or neoplastic diseases that cause abnormal enlargement of the uterus, three inches below the umbilicus can be the location of the uterus. If the patient has abdominal pain with various conditions such as abnormal vaginal bleeding and discomfort in the lower abdomen, gastrointestinal disorders and urinary disorders are ruled out, and gynecological disorders are the key consideration. Patients need to do gynecological internal examination and gynecological ultrasound to initially determine the location of the uterus, and then determine the next step of examination and treatment based on the examination results.
