Is fasting mandatory before surgery?

Did you know that before starting surgery, you are required to fast without drinking even a sip of water for at least 6 hours? Depending on the type of anesthesia and the surgical procedure, fasting for at least 8 hours may also be required. This must be done to empty the stomach, partly so that the anesthesia can be administered properly. Even candy and a sip of water will be double-checked by the nurse before surgery! In Korea, this rule is extremely strict, and for your own good, never lie to the nurse! hihi. Below we will try to explain a little bit about the reasons why.

Briefly explained, if you do not fast before surgery, your stomach contents can flow back into your lungs when you are under anesthesia, which can lead to airway obstruction or serious infections such as pneumonia. Therefore, it is recommended to fast when you are scheduled for surgery under either local or general anesthesia.

Is fasting also mandatory after waking up from surgery?

Unlike before surgery, where you must fast for at least 6 hours, for at least 1-2 hours after waking up, you are still not allowed to drink or eat.

Why is that?

After being anesthetized, the body's organs are also anesthetized and do not function properly. Immediately after surgery, you must be careful with food or even a sip of water because of the remaining effects of the anesthesia.

Each anesthesia is different, but some people may feel unwell or experience vomiting and dizziness, so it is best to drink a little warm water first (about 1-2 hours after surgery), and if there are no problems, you can eat a light meal. Eating immediately after surgery can cause vomiting, nausea, and stomach pain.

Although there may be differences in the duration of fasting, light local anesthesia of course does not require fasting. If you have undergone surgery under general anesthesia, you must be more careful. You may be thirsty and hungry due to fasting, but you must endure it for the sake of a safe surgical outcome.
