Weight loss results vary from patient to patient and there are many factors may influence results. Recent studies have shown favourable results at 1, 2 and 3 years following Gastric Sleeve surgery, with 60% expected excess weight loss at the end of the first year. The weight loss achieved with the gastric sleeve is a result of two combining factors: the smaller stomach size and the removal of the hunger stimulating hormone, Ghrelin.

Factors influencing weight loss include

• Weight at the Time of Surgery
• Age of the Patient
• Motivation Levels
• Support Network
• Personal Health
• Compliance with Dietary, Medical, and Behavioural Advice
• Exercise
• Dietary Habits

There are certain dietary requirements and expectations before and after surgery that also need to be taken into consideration. Generally, patients undergoing Gastric Sleeve Sugery are put on a fluid diet-Formulated Meal Replacements-for the first 2 weeks prior to surgery and again for the first 2 weeks after surgery. Patients will then progress to a puree diet for the next 2 weeks before reintroducing solid foods to their diet around a month after surgery. It is extremely important to adhere to these requirements, since the pre-surgical fluid phase allows the surgeon easier access to the working area around the stomach and contributes to the healing process after surgery; and, the post-surgical fluid and puree phase will again compliment healing and prepare the stomach for the transition back to solid foods. Once back on solid foods, patients are advised to change some of their eating habits and drink plenty of water throughout the day. Our dietitian will be able to assist you with your pre and post-surgical diet phases.

As with all weight loss procedures, there is a strong emphasis on lifestyle changes that include healthy eating habits and exercise. Here are some recommendations:

Modify your Eating Habits

• Always sit down and relax whilst eating
• Chew your food well before swallowing
• Avoid drinking any liquids when eating
• Stop eating as soon as you start to feel full
• Eat regularly and avoid skipping meals
• Accept that it’s okay to leave food on your plate

Get Active

It is important to appreciate the benefits of leading a more active lifestyle. Looking for opportunities to be more active is a healthy start and incidental exercise can have a massive impact on weight loss results. Confidence increases as self-efficacy improves and incidental exercise provides the perfect foundation for more dedicated activities later on. Dedicated exercise often requires some commitment and can be difficult for those who lead extremely busy lifestyles; however, it’s important and should be considered to compliment incidental activities as soon as possible. Building motivation for dedicated activities can be a challenge, since enjoyment and efficacy is the key to sustaining this commitment. Our psychologist can assist you with strategies for building motivation; and, provided you have been cleared by your doctor to start participating in dedicated exercise activities, can also help you set realistic and achievable goals.
