Gastric Sleeve

Gastric Sleeve surgery, also known as Sleeve Gastrectomy, is a significant weight-loss procedure that has gained popularity in the field of bariatric surgery.

This procedure involves the removal of approximately 80% of the stomach, leaving a tube-like portion of the stomach in place, which is often compared to the size and shape of a banana.

This drastic reduction in stomach size limits the amount of food that can be consumed and helps to decrease hunger sensations by reducing the production of the hunger hormone, ghrelin.

Gastric Sleeve surgery not only aids in substantial weight loss but also contributes to improvements in various obesity-related health conditions like Type 2 diabetes, high blood pressure, and sleep apnea. It is a permanent, irreversible procedure that requires a lifelong commitment to maintaining a healthy lifestyle and diet.

Who is Eligible for Gastric Sleeve Surgery?

Eligibility for Gastric Sleeve Surgery, or Sleeve Gastrectomy, typically includes the following criteria:

1. Body Mass Index (BMI): Individuals with a BMI of 40 or higher are often considered prime candidates for this surgery. Those with a BMI between 35 and 40 may also be eligible if they have obesity-related health conditions such as Type 2 diabetes, high blood pressure, severe sleep apnea, or other weight-related health issues.
2. Previous Weight Loss Efforts: Candidates are usually those who have tried and failed to lose weight through diet, exercise, and other conventional methods.
3. Age: Most candidates are between the ages of 18 and 65. However, exceptions can be made based on individual health circumstances and the potential benefits of the surgery.
4. Overall Health: Candidates should be healthy enough to undergo a major operation. This includes having no uncontrolled psychological conditions or other medical issues that could complicate surgery or anesthesia.
5. Understanding and Commitment: A candidate must understand the risks and benefits of the surgery and be committed to lifelong dietary, lifestyle, and medical changes post-surgery. This includes adherence to nutritional guidelines, exercise regimens, and regular medical follow-ups.
6. Psychological Evaluation: Many bariatric surgery programs require a psychological evaluation to ensure that the individual is mentally prepared for the surgery and the subsequent lifestyle changes.
7. Insurance and Financial Considerations: Some insurance companies have specific criteria that need to be met for coverage of the surgery. Patients should also consider the financial implications if not covered by insurance.

Each case is evaluated individually, and the final decision is made by a team of healthcare professionals, including surgeons, dietitians, and psychologists, to ensure the best outcome for the patient.

How Much Weight Can You Expect to Lose?

The amount of weight you can expect to lose following Gastric Sleeve Surgery (Sleeve Gastrectomy) varies from person to person, but there are general trends observed in most patients:

1. Percentage of Excess Weight Loss: Patients typically lose between 50% to 70% of their excess body weight. The term "excess body weight" refers to the amount of weight above what is considered the normal weight for an individual's height.
2. Time Frame: The majority of this weight loss usually occurs within the first year after surgery. It's common for the rate of weight loss to be higher in the initial months post-surgery and then gradually slow down.
3. Factors Influencing Weight Loss: The exact amount of weight loss can be influenced by several factors, including:
   • Pre-surgery weight: Individuals with higher initial body weight might lose more pounds.
   • Adherence to Dietary Guidelines: Success in weight loss is significantly impacted by following the post-surgery diet and nutrition plan.
   • Physical Activity: Incorporating regular exercise enhances weight loss and overall health.
   • Age and Metabolic Rate: Younger individuals and those with a higher metabolic rate might experience more significant weight loss.
   • Individual Health Conditions: Certain health conditions can affect weight loss.
4. Long-term Weight Maintenance: After the initial period of rapid weight loss, the focus shifts to maintaining that weight loss. This requires a lifelong commitment to healthy eating habits, regular physical activity, and ongoing medical follow-ups.

It's important to set realistic expectations and understand that Gastric Sleeve Surgery is a tool to help with weight loss. It works effectively when combined with lifestyle changes. Additionally, individual results can vary, and discussing your specific situation with a healthcare provider is essential for a more accurate prediction.

How Long is The Recovery Period?

The recovery period after Gastric Sleeve Surgery, or Sleeve Gastrectomy, can vary depending on several factors such as the individual's overall health, the specific technique used for the surgery, and how well the patient follows post-operative care instructions. However, a general timeline for recovery is as follows:

1. Immediate Post-Operative Period (Hospital Stay): Most patients stay in the hospital for about 2 to 3 days following the surgery. During this time, medical staff monitor recovery, manage pain, and ensure that the patient can tolerate liquids.
2. First Few Weeks:
   • First 1-2 Weeks: Recovery at home. During this period, patients are usually on a liquid diet and gradually transition to pureed foods.
   • Activity: Patients are encouraged to start light activities like walking as soon as possible post-surgery to reduce the risk of blood clots and other complications.
   • Work: Returning to work depends on the nature of the job. For desk jobs, patients might return within 2-4 weeks, while more physically demanding jobs might require a longer absence.
3. One to Three Months:
   • Diet: Transition from pureed to soft foods, and eventually to regular, but smaller and healthier meals.
   • Physical Activity: Gradual increase in exercise intensity, as tolerated.
4. Long-term Recovery:
   • Complete Healing: It typically takes around 6 months for the body to fully heal from the surgery.
   • Lifestyle Changes: Ongoing commitment to dietary guidelines, exercise, and regular follow-ups with healthcare providers is essential.
5. Psychological Adjustment: Some patients may also need time to psychologically adjust to their rapid weight loss and changing body image.

It's important for patients to closely follow their surgeon's instructions and attend all follow-up appointments to ensure a smooth recovery. The recovery experience can differ from person to person, and it's crucial to communicate with healthcare providers about any concerns or complications that arise during this period.

Will I Need a Special Diet After Surgery?

Yes, after Gastric Sleeve Surgery (Sleeve Gastrectomy), you will need to follow a special diet. This diet is crucial for proper healing, maximizing weight loss, and avoiding complications. The post-surgery diet typically progresses through several stages:

1. Liquid Diet (1-2 weeks post-surgery):
   • Immediately after surgery, you will start with a clear liquid diet. This includes broth, unsweetened juice, and sugar-free gelatin.
   • Gradually, you'll move to other liquids like milk, unsweetened puddings, and thin soups.
2. Pureed Foods (2-4 weeks post-surgery):
   • After tolerating liquids, you can eat pureed foods. This includes pureed fruits, vegetables, lean meats, and beans.
   • Foods should be blended with a liquid (like water, fat-free milk, or broth) to a smooth, baby-food consistency.
3. Soft Foods (4-8 weeks post-surgery):
   • Soft, easy-to-chew foods are introduced next. Examples include soft fruits and vegetables, eggs, and tender meats.
   • Continue to avoid foods that are hard to digest, such as bread, rice, and tough meats.
4. Regular Diet (After 8 weeks):
   • Gradually, you'll transition to a more regular diet, focusing on small, nutrient-rich, and low-calorie meals.
   • It's important to chew food thoroughly and eat slowly.

Throughout all these stages, you should:

• Stay Hydrated: Drink plenty of water throughout the day, but avoid drinking 30 minutes before and after meals to prevent overfilling your smaller stomach.
• Avoid Certain Foods: Steer clear of sugary, fatty, or very fibrous foods.
• Monitor Portion Sizes: Eat small portions to avoid stretching your stomach.
• Take Supplements: You may need to take vitamin and mineral supplements, as recommended by your healthcare provider, since nutrient absorption can be affected post-surgery.

This dietary progression helps your stomach heal without being overstretched by the food you eat. It's essential to follow the diet plan provided by your healthcare team and attend all follow-up appointments to monitor your progress and nutritional status. Each individual's post-surgery diet plan might differ slightly, so it's important to get personalized advice from your dietitian or surgeon.
