Stop Eating Before Surgery: How Long?
It’s absolutely essential to plan carefully before surgery. As a patient, it is your responsibility to pay attention to the pre-op instructions your doctor gives you. One of the most important instructions is to limit your food intake before surgery. Knowing exactly how long you should stop eating before your next procedure is key since eating close to the time of your operation can cause serious complications. In this article, we will discuss why you should avoid eating before surgery, and how long exactly you should wait.
1. Pre-Surgery Eating Restrictions

Before any surgery, your doctor will usually tell you to stop eating before surgery. There are a number of reasons why this is necessary – the main ones being to help reduce the risk of complications and to make the surgery easier for the anesthesiologist. While the amount of time you should stop eating before surgery varies depending on the type of surgery and your doctor’s instructions, it is important to be mindful of when to stop eating before surgery.
Why Is it Important to Stop Eating Before Surgery?
Stopping eating before surgery is necessary for a few key reasons. The most important of these is to enable your surgery to take place safely with as little risk of complications as possible:
- If you eat anything, the risk of aspiration (inhaling food or liquid into the lungs) increases significantly during general anesthesia.
- It can cause stomach contents to be brought up into your throat during the surgery, leading to an increased risk of complications.
- It reduces the risk of vomiting during surgery, which can lead to breathing difficulties and other complications.
In addition, it makes it easier for the anesthesiologist to adapt the anesthesia to your needs, as the presence of food in your stomach can lead to unpredictable changes in your body chemistry.
2. What Are the Guidelines?
When it comes to surgery, nutrition is a very important factor. If you are planning to go into surgery, it is essential to understand the guidelines when it comes to eating in the days before the operation.
Food and drink restrictions before surgery vary depending on the type and complexity of the operation. Generally, you can expect to fast from the day of your surgery, but you may also need to start fasting beforehand.
- The general rule is no food or drinks 8 hours before your surgery. This can mean the evening before.
- This timeline can vary, depending on the procedure and your regular eating schedule. Your doctor may have specific instructions.
- You may be advised to not have anything to eat or drink after midnight the night before surgery.
It is important to follow all of your doctor’s instructions very closely for the best outcome. Discuss any questions or concerns with your doctor about when you need to stop eating before surgery. Disregarding your doctor’s instructions can be very dangerous and delay your surgery.
3. Benefits of Refraining from Eating Before Surgery

When a patient is preparing for surgery, it is important to refrain from eating or drinking for a certain period of time prior to the procedure. In most cases, it is recommended that no food or drink is consumed for at least 8-12 hours before surgery. This is known as fasting.
Here are a few benefits of fasting before surgery:
- Reduces the risk of vomiting during or after surgery.
- Decreases the risk of complications related to general anesthesia.
- Decreases the risk of aspiration, which is when food or fluids from the stomach are unintentionally inhaled during the anesthetic process.
Additionally, fasting before surgery helps keep the patient comfortable and it limits the interactions between food and metabolic changes that may occur when anesthesia is administered.
Fasting helps to decrease risks and ensure optimal surgical outcomes. Therefore, it is important for patients undergoing surgery to follow the pre-operative fasting instructions issued by their doctor or surgeon.
4. How Long Before Surgery?
The answer to this question depends on the type of procedure you are having. It is generally suggested that you follow the instructions of the surgical team and not try to fast for more than the recommended time:
- Gastrointestinal procedures: The fasting time for these surgical procedures is usually between six to eight hours before the surgery.
- Orthopedic procedures: In most cases, those having orthopedic surgeries are instructed to fast for at least 10 to 12 hours before the surgery.
- Elective surgeries: Elective surgeries do not require fasting, however, it is important to follow the doctor’s instructions to ensure a safe and successful surgery.
If you are unsure how long you should stop eating before your surgery, speak to your doctor and ask him/her. They are the best person to give you the correct advice for your individual situation.
It is important to remember that it is not safe to fast for too long before major surgeries. Fasting for a prolonged period of time can lead to dehydration, low blood sugar levels, and other complications that could put you at risk during the operation.
5. Tips for Pre-Surgery Hunger Management

There are several things to consider when trying to manage hunger before surgery. Not eating for an extended period of time can be difficult, so here are some tips to make it easier:
- Drink plenty of fluids – keep yourself hydrated before your operation by drinking water, juice, or tea.
- Consider the timing of your meals – try eating smaller, frequent meals throughout the day as well as avoiding certain foods such as dairy and processed food.
- Follow dietary advice – consult with your healthcare provider for specific dietary advice.
- Add healthy snacks – prepare nutritious snacks such as carrot sticks, celery, fruits, or unsalted nuts.
- Keep busy – try and stay distracted by activities such as reading, playing games, watching TV, or listening to music.
By following these tips, you can be better prepared for any pre-surgery fasting you may have to do. Remember that it is important to follow your healthcare provider’s instructions and ask questions.
