Theoretically, hysterectomy may lead to an increase in abdominal volume and thus a smaller abdomen. However, there are two main factors to consider when the abdomen becomes larger after hysterectomy: 1) significant thickening of the abdominal fat layer, that is, hypertrophy of the fat layer of the abdominal wall due to obesity; 2) increase in the volume of the abdominal appearance due to intestinal distention. In order to prevent other adverse effects, it is recommended to perform obstetrical and gynecological ultrasonography and abdominal ultrasonography and, if necessary, abdominal plain film to exclude intestinal diseases. Hysterectomy is one of the common surgical operations in obstetrics and gynecology and is often used to treat uterine fibroids, adenomyosis, endometrial hyperplasia and other diseases, and is also one of the basic operations that must be performed in cases of obstetrical and gynecological malignancies.
