You can’t drink water 4 hours before the abortion surgery, and you can’t eat 6 hours before the surgery, this is for the painless abortion surgery. Because painless abortion surgery requires anesthesia, when the anesthesia is injected, the entire digestive tract is in a state of relaxation, if you drink water before the surgery, there is a possibility that the surgery will lead to liquid entering the trachea, which can lead to tracheal asphyxiation and serious complications. Therefore, the dietary requirements before the painless abortion procedure are very strict, and you must follow what the doctor says, otherwise there is no way to do the procedure. In case of a painful abortion procedure, these restrictions are not needed and you can drink and eat anytime you want.
