One of the most common instructions before surgery is fasting but many patients don’t fully understand why it is necessary.

Fasting before anaesthesia is crucial to prevent a serious complication known as aspiration. During anaesthesia, your body’s reflexes are temporarily reduced, including the ability to prevent stomach contents from entering the lungs. If food or liquid is present in the stomach, it can lead to life-threatening complications.

Typically, patients are advised to avoid solid food for at least 6–8 hours before surgery and clear liquids for a shorter duration, depending on medical guidelines.

However, not all fasting rules are the same. The duration may vary based on the type of surgery, age, and medical condition. That’s why it’s important to strictly follow your anesthesiologist’s instructions.

Many patients assume that skipping fasting rules won’t make a difference but even small amounts of food or drink can increase risks during anaesthesia.
If you accidentally eat or drink before surgery, it is important to inform your doctor honestly. In some cases, the procedure may need to be delayed for safety.

Fasting is not just a routine instruction, it is a critical step in ensuring a safe surgical experience.
