Why can't people eat before surgery?

Patient's question:

I am 27 years old. The last time I had sex with my boyfriend, we didn't use protection, and now I am pregnant. However, I don't want this child and plan to have an abortion. Why can't I eat before an abortion procedure?

Doctor's answer:

Preoperative patients cannot defecate because abortion procedures require anesthesia. After anesthesia, gastrointestinal reactions may occur again. If there is food in the stomach, it may be vomited out, enter the trachea, and cause breathing difficulties. Not only can patients not defecate before an abortion, but they must also fast for at least eight hours before any surgery that requires anesthesia to avoid unexpected incidents during the procedure. In daily life, patients should maintain a balanced nutritional intake, engage in aerobic exercises to strengthen their bodies, and keep a positive mood to enhance their physical condition and accelerate recovery.
