What is Post Bariatric Surgery Diet?

Post bariatric surgery diet refers to the dietary plan that individuals need to follow after undergoing bariatric surgery. The primary goal of the post-bariatric surgery diet plan is to optimize health and help patients reach their desired weight. The diet plan can vary depending on the type of bariatric surgery, including laparoscopic sleeve gastrectomy, Roux-en-Y gastric bypass, adjustable gastric band, and more. Regardless of the type of bariatric surgery, however, the post-surgery diet plan generally involves several stages.

Stage 1: Clear Liquids

The clear liquid stage starts right after the surgery and lasts for approximately 1-2 days. At this stage, patients are only allowed to drink clear liquids, such as water, broth, tea, and sugar-free gelatin. The purpose of this stage is to prevent dehydration, provide adequate hydration, and help the stomach heal after surgery.

Stage 2: Full Liquids

During the full liquid stage, patients can start consuming liquids that are more substantial than clear liquids. This stage usually lasts between 7 to 14 days, depending on the surgeon’s recommendations. Patients can consume drinks like protein shakes, low-fat milk, and strained low sugar fruit juice.

Stage 3: Pureed foods

After the clear and full liquid stages, patients are ready to move on to pureed foods. Pureed foods are foods that have been blended or mashed into a soft consistency. This stage usually lasts between 2 to 4 weeks. Examples of pureed foods that can be consumed include hummus, cottage cheese, mashed sweet potato or avocado, and baby food.

Stage 4: Soft Foods

After the initial stages have been completed, patients are ready to move on to soft foods. The soft food stage usually starts four to six weeks after surgery, and patients can gradually introduce soft foods to their diet. Examples of soft foods include scrambled eggs, baked fish, cooked vegetables, and canned fruits.

Stage 5: Regular Foods

Once the patient can tolerate soft foods without any issues, they can start introducing regular foods back into their diet. However, it’s important to note that patients need to avoid high-fat, high-sugar, and high-calorie foods if they want to maintain their weight loss.

What to Eat After Bariatric Surgery?

Following bariatric surgery, it’s essential to eat a well-balanced diet that is rich in nutrients and low in calories. The right balance of macronutrients, including protein, carbohydrates, and fats, is crucial for optimal health after surgery.

Protein should be the cornerstone of the post-bariatric surgery diet as it helps in maintaining and building muscle mass. The suggested intake of protein for bariatric patients is at least 60-80 grams per day. Protein-rich foods include lean meat, poultry, fish, eggs, cottage cheese, Greek yoghurt, and legumes.

Carbohydrates, especially simple carbohydrates, should be limited after bariatric surgery to promote weight loss. Complex carbohydrates such as quinoa, brown rice, and whole grains should be included in the diet as they are rich in fibre and aid in digestion.

Fats need to be limited as well. Healthy fats such as olive oil, avocado, and nuts can be included in the diet in small amounts.

What to Avoid After Bariatric Surgery?

After bariatric surgery, there are certain foods and beverages that patients need to avoid to prevent complications and maximize weight loss. These include:

Food and Beverages to Avoid Reasons to Avoid
Carbonated Beverages May cause discomfort, bloating, and stomach upset
Fried Foods High in calories, fat, and salt, resulting in weight gain and digestive issues
Sugary foods and drinks High in calories, sugar, and carbohydrates, leading to weight gain and blood sugar issues
Tough meats, bread, and raw vegetables Difficult to digest and may cause discomfort

Meal Planning Tips for Post-Bariatric Surgery Diet

Meal planning is essential in ensuring that patients follow a healthy diet plan after bariatric surgery. Here are some tips for meal planning:

Tip 4: Chew Slowly and Thoroughly

Chew your food slowly and thoroughly as it aids in digestion and helps you feel full faster.
