Following gastric sleeve surgery, adhering to a specialized diet is essential for recovery and long-term success. Bay Surgery, under the expert guidance of Dr. Daniel Mafi, a specialist in weight loss surgery in Tauranga, emphasizes a structured approach to eating that progresses through four distinct stages. This method ensures that patients receive the necessary nutrients for healing while gradually adjusting to their new gastric sleeve.

Stage 1 – Fluids: Weeks 1 to 3

The initial postoperative phase focuses on fluid intake to avoid dehydration and ensure that the stomach heals without being strained by solid foods. During the first week, gastric sleeve surgery patients are encouraged to start with small sips, gradually increasing to approximately 200ml per hour. Initial beverages should be clear fluids like water, diluted squash, various teas, clear broth, and apple juice. As patients progress, they can incorporate nutrient-rich liquids like skimmed milk, smooth soups, and protein-enriched drinks, aiming for a minimum of 60g of protein and 2 to 2.5 litres of total fluids daily.

Stage 2 – Pureed Foods: Weeks 3 to 4

Once liquids are well-tolerated, patients can move on to pureed foods. Foods should be blended to a smooth, yogurt-like consistency. Suitable options include soggy Weetabix, blended tinned fruit, mashed potato, and liquidized meats with vegetables. Gastric sleeve patients should aim for four to six small meals daily, consisting of one to two tablespoons each, gradually increasing to four tablespoons. It’s crucial to include protein in each meal and maintain a 30-minute gap between eating and drinking to optimize digestion.

Stage 3 – Soft and Crispy Foods: Weeks 5 to 6

The third stage introduces soft foods, which can include minced meats, fish, scrambled eggs, and cooked vegetables. Once patients can tolerate these, they may add crispy foods like melba toast. It’s important to reduce meal frequency to three to four times a day and continue the practice of not snacking between meals. Chewing food thoroughly, up to 20 times per mouthful, is essential to aid digestion and prevent discomfort.

Stage 4 – Normal Diet: Weeks 7 to 8

By weeks seven to eight after gastric sleeve surgery, patients are typically ready to resume a normal diet, consuming nearly any type of food in solid form. The goal is to have three balanced meals per day, with total caloric intake between 1000 and 1200 kcal. Patients should listen to their bodies and introduce new foods gradually to monitor for any adverse reactions, particularly with foods known to be more challenging to digest post-surgery, such as dairy, chewy meats, and fibrous vegetables.

Foods to Avoid

Post-surgery, certain foods may no longer be tolerated as before. It’s advisable to avoid or introduce slowly foods like chewy meats, white bread, nuts, and seeds. High-fat and high-sugar foods such as crisps, biscuits, and sweets should be minimized to aid in weight loss efforts. Additionally, all fizzy drinks should be avoided due to the risk of gas and bloating.

Key Points for Ongoing Success

• Regular Meals: Eat three small, healthy meals a day with no more than five hours between them. Consistency is key, even if you don’t feel hungry.

• Manage Hunger: If hungry between meals, try drinking water first to distinguish between hunger and thirst. If still hungry, opt for a healthy snack.

• Eating Habits: Eat slowly, placing small amounts in your mouth and chewing extensively.

• Portion Control: Do not eat until full to avoid stretching the stomach pouch and potential vomiting.

• Fluid Intake: Ensure a daily intake of 1.5 to 2 liters of fluids, but not during or immediately after meals.

Following these guidelines and the expertise of Dr. Daniel Mafi, patients can optimize their recovery and weight loss outcomes after gastric sleeve surgery. The focus on a gradual dietary progression not only aids in healing but also helps patients adapt to a healthier lifestyle for long-term success.
