How long do you need to not eat before have surgery?

Typically, patients are required to fast for 6 to 8 hours before undergoing surgery. The specific time you need to fast will depend on the type of surgery you are having.

You will usually be given specific instructions about fasting before surgery by your doctor or the hospital or surgery center where you are having the procedure. It is important to follow these instructions carefully to reduce the risk of complications during surgery.

Here are some common guidelines about fasting before surgery:

* You should not eat or drink anything (including water) after midnight the night before your surgery.

* Some doctors may allow you to have a clear liquid such as water, coffee, or tea (without milk or sugar) up until 2 hours before your surgery.

* You should tell your doctor about any recent changes in your diet, such as starting a new weight loss plan or taking any new dietary supplements.

* If you have any questions about fasting before surgery, be sure to discuss them with your doctor.
