The criteria for the cure of hyperemesis gravidarum is the return of chorionic gonadotropin to the normal range and no recurrence within one year. Hyperemesis gravidarum is a special kind of gynecological disease, which is mainly caused by the excessive proliferation of placental chorionic trophoblast cells after pregnancy, which makes the interstitium of placenta cells edematous, and finally forms a large number of blisters similar to grapes. The treatment is mainly based on purging and scraping, after which the patient’s chorionic gonadotropin needs to be rechecked every month, and it is considered to be cured if it continues to decrease to the normal level and does not recur within a year. Most of the patients can recover after the operation, only a few patients are malignant and need systemic chemotherapy or even hysterectomy.
