Introduction

In general, patients should not eat or drink before surgery, primarily to avoid anesthesia-related risks, reduce surgical complications, minimize symptoms such as vomiting or nausea, and manage conditions like gastric ulcers and diabetes. It is recommended to consult a doctor for specific advice. Patients are advised to strictly follow medical instructions regarding fasting and fluid restriction, which helps reduce surgical risks, ensure patient safety, and promote recovery.

Generally, patients should not eat or drink before surgery, primarily to avoid anesthesia risks, reduce surgical complications, minimize nausea or vomiting, and manage conditions such as gastric ulcers and diabetes. It is recommended to consult a doctor for personalized advice. Specific reasons are as follows:

1. Avoiding Anesthesia Risks: Anesthetic drugs may cause relaxation of the patient's esophageal sphincter, allowing stomach contents to reflux into the esophagus or mouth. Fasting before surgery helps prevent regurgitation and accidental aspiration of food.

2. Reducing Surgical Interference: Surgery requires anesthesia, and if food is consumed beforehand, stomach contents may reflux into the airway under anesthesia, potentially causing dangerous situations such as choking or airway obstruction.

3. Minimizing Nausea or Vomiting: Postoperative discomfort, including nausea and vomiting, is common. Eating or drinking can trigger adverse reactions and prolong recovery time.

4. Gastric Ulcers: Patients with gastric ulcers may require gastroenterological procedures such as endoscopy. Consuming food or drinks before surgery can impair visibility during the procedure and increase surgical difficulty.

5. Diabetes: For diabetic patients, the body is under stress during surgery, leading to increased insulin resistance and difficulty in blood glucose control. Eating or drinking before surgery may cause a sharp rise in blood sugar levels, increasing the risk of infection and impairing wound healing.

Patients are advised to strictly follow medical instructions regarding fasting and fluid restriction, which helps reduce surgical risks and ensures patient safety.
