What Can You Eat Before Bariatric Surgery: Preoperative Dietary Guidelines 

Before undergoing bariatric surgery, it is crucial to follow specific dietary guidelines to ensure a safe and successful procedure. These guidelines are designed to prepare your body for surgery and optimize the outcomes. Here are some important preoperative dietary guidelines to keep in mind: 

  1. Follow a low-calorie diet: Your healthcare team will provide you with a specific calorie target to achieve before surgery. This usually involves consuming a low-calorie diet to help reduce liver size and minimize the risk of complications during the procedure. 
  2. Increase protein intake: Protein is essential for tissue repair and healing after surgery. Prioritize consuming lean sources of protein such as poultry, fish, eggs, and legumes. Aim for at least 60-80 grams of protein per day to support optimal recovery. 
  3. Avoid high-sugar and high-fat foods: It is important to limit your intake of sugary beverages, desserts, fried foods, and processed snacks. These foods can contribute to weight gain and increase the risk of post-surgery complications. 
  4. Stay hydrated: Adequate hydration is essential for overall health and helps prevent dehydration during the preoperative period. Aim to drink at least 64 ounces (8 cups) of water daily unless otherwise advised by your healthcare team. 

Remember, these preoperative dietary guidelines are tailored to each individual’s needs. It is crucial to consult with your healthcare team or a registered dietitian who specializes in bariatric surgery to create a personalized plan that suits your specific requirements. By following these guidelines, you can optimize your chances of a successful surgery and enhance your overall well-being.
