The common causes of vomiting even after abortion surgery are surgical irritation during abortion surgery, post-abortion syndrome, failed abortion surgery, gastroenteritis, and psychological factors. It is normal to feel like vomiting for a few hours after abortion due to the stimulation of the uterus when performing abortion. After abortion surgery, some women may experience abortion surgery syndrome, which mainly manifests as dizziness, headache, nausea, vomiting, etc. If the abortion fails and the body continues to secrete estrogen and progesterone after the operation, nausea and vomiting will easily occur. It is recommended to review the ultrasound one week after the abortion to see if the abortion is clean. If you do not pay attention to abdominal warmth after abortion, or if you eat bad food that causes gastroenteritis, you may also experience vomiting. If you are overly nervous after an abortion, you may also experience gastrointestinal reactions and vomiting.
