Doctors and surgeons advise their patients to fast (no eating or drinking) for at least eight hours before their laproscopic surgery, according to WebMD. This is because laproscopic surgery is usually done under general anesthesia.
Laproscopic surgery is a procedure in which surgeons view the internal organs for signs of endometriosis. If any endometriosis implants or scar tissue are discovered, they are removed, explains WebMD.
For surgical procedures that involve general anesthesia, it is important patients do not eat beforehand because when they are put under they are no longer able to control their gag reflex, reports Banner Health. This means if there is food in the stomach, it could be regurgitated, causing patients to choke. This is called pulmonary aspiration and it can be fatal.
