Women usually need to go to the hospital gynecology department for postpartum review 42 days after delivery, whether by normal delivery or by cesarean section. Usually, there are three kinds of routine items for postpartum review: the first one is the ultrasound of uterine adnexa; the second one is the blood routine; the third one is the white belt routine. There is also a group of people who need to test the recovery of blood sugar and blood pressure due to special diseases, such as patients with gestational diabetes or hypertension. Patients with intrahepatic cholestasis or abnormal liver function during pregnancy also need to review liver and kidney function and bile acids. Generally speaking, the review of liver and kidney function requires a blood test on an empty stomach, while routine blood and white belt tests as well as gynecological ultrasound do not require an empty stomach and can be done directly at the gynecological department of the hospital. At the same time, most tertiary hospitals now also carry out postpartum pelvic floor muscle function review, which varies from hospital to hospital due to differences in equipment. Most secondary hospitals do not have this program now, and it is not mandatory. Therefore, the specific items to be reviewed will depend on the instruments and equipment of the hospital where the review will take place.
