Why is Diet Before the Surgery Important?
A pre-bariatric diet is an essential component of the optimization process for bariatric surgery, which is a weight loss surgery performed on individuals with severe obesity. The primary goals of a pre-bariatric diet are to reduce the size of the liver, promote weight loss, and improve overall surgical outcomes. Here are some reasons why a pre-bariatric diet is important:
Reducing liver size: Many individuals with obesity have an enlarged liver due to excess fat accumulation. The liver sits right above the stomach and can obstruct the surgeon’s view and access during the procedure. A pre-bariatric diet, typically low in calories and carbohydrates, helps shrink the liver by utilising its glycogen stores. This makes the surgery safer and lessens the risk of complications during the operation.
Facilitating weight loss: Losing weight before surgery can have several benefits. It reduces the amount of intra-abdominal fat, which makes the surgery technically easier for the surgeon. Weight loss can also improve overall health, decrease the risk of surgical complications, and increase the success rate of the procedure.
Preparing for dietary changes: Bariatric surgery involves altering the digestive system to promote weight loss. After the surgery, patients need to make significant changes to their eating habits and adhere to a specific post-operative diet. Following a pre-bariatric diet helps patients adapt to the dietary restrictions and guidelines they will have to follow after the surgery, making the transition smoother and more manageable.
Assessing dietary compliance: The pre-bariatric diet allows healthcare providers to assess a patient’s commitment to making necessary lifestyle changes. Compliance with the pre-operative diet is an indication of the patient’s ability to adhere to the post-operative diet and lifestyle modifications, which are crucial for long-term success after bariatric surgery.
Improving overall health: The pre-bariatric diet often includes nutritious, balanced meals that are lower in calories and higher in protein. Following this diet can lead to improvements in overall health, such as lowering blood pressure, reducing cholesterol levels, and stabilising blood sugar levels. These changes not only contribute to better surgical outcomes but also set the stage for long-term health improvements.
It’s important to note that the specifics of a pre-bariatric diet can vary depending on the individual and the recommendations of the healthcare team overseeing the surgery. It is crucial for patients to follow the guidance of their healthcare providers to maximise the benefits of the pre-bariatric diet and optimise their overall surgical experience.
The pre-bariatric surgery diet, also known as a pre-operative or pre-op diet, is a crucial part of the preparation process for bariatric surgery. It must start a minimum 3 weeks before the D-day.
The specific guidelines may vary depending on the surgeon and the individual’s unique circumstances, so it’s essential to follow the instructions provided by your healthcare team. However, here is a general overview of what a pre-bariatric surgery diet may entail:
Calorie restriction: The pre-op diet typically involves reducing calorie intake to promote weight loss and shrink the liver. The calorie range can vary, but it is often around 800-1200 calories per day.
Protein focus: Protein is an important nutrient for muscle maintenance and healing after surgery. Your healthcare team may recommend consuming a high-protein diet during the pre-op phase. Good sources of protein include lean meats, poultry, fish, eggs, low-fat dairy products, legumes, and tofu.
Limited carbohydrates: Carbohydrate intake may be restricted to facilitate weight loss and reduce liver size. Simple carbohydrates such as sugary foods and drinks, white bread, and pastries are usually eliminated or minimized. Instead, focus on complex carbohydrates like whole grains, vegetables, and fruits in moderation.
Healthy fats: While calorie intake is restricted, it’s still important to include small amounts of healthy fats in your diet. Choose sources such as avocados, nuts, seeds, and olive oil.
Hydration: Staying hydrated is essential. Drink plenty of water throughout the day, and avoid sugary beverages or carbonated drinks. However, follow the specific guidelines provided by your healthcare team regarding fluid intake.
Avoid alcohol and caffeine: Alcohol and caffeine intake is typically restricted during the pre-operative period due to their potential effects on blood clotting, hydration, and nutrient absorption. Follow your healthcare team’s guidance regarding the consumption of these substances.
Vitamins and mineral supplements: Your healthcare team may prescribe specific vitamin and mineral supplements to ensure you meet your nutritional needs during the pre-op diet. Follow their recommendations and take the supplements as directed.
Follow the recommended timeline: The pre-bariatric diet duration can vary, but it is typically followed for a few weeks leading up to the surgery. Be sure to adhere to the specific timeline provided by your healthcare team.
Remember, the pre-bariatric surgery diet is an important step in preparing for the surgery and maximising its success.
