On Dr. Abdullah Al-Munifi’s website, specializing in bariatric and laparoscopic surgery, we provide you with all the information you need about this sensitive procedure, which requires a high level of medical expertise.

In this article, we will cover all aspects of gastric sleeve surgery, from the basic principles to the expected outcomes, with a focus on providing accurate and reliable information.

Information About Gastric Sleeve Surgery: What Is It and How Does It Work?

Gastric sleeve surgery, or Gastrectomy, is a surgical procedure in which the size of the stomach is significantly reduced. It is classified as one of the modern and highly effective bariatric surgery procedures.

How Gastric Sleeve Surgery Works

In gastric sleeve surgery (as it is commonly called), approximately 75–80% of the stomach is removed, which leads to:

• Reduced capacity: the stomach becomes the size of a banana instead of its original size
• Reduced hunger: decreased secretion of the hormone ghrelin, which is responsible for hunger
• Reduced food intake: the patient feels full quickly with smaller amounts of food
• Improved digestion: the way food is processed in the digestive system improves

Advantages of Gastrectomy

Gastric sleeve surgery offers several advantages that make it the first choice for many:

• Effective and rapid results: loss of 60–80% of excess weight within one year
• Less complex procedure: compared to some other surgeries, gastrectomy is simpler
• Improvement of associated conditions: reduction in blood pressure and improvement in diabetes
• No impact on nutrient absorption: unlike intestinal bypass procedures
• Positive psychological outcomes: improved quality of life and self-confidence

Gastric Sleeve Surgery Requirements: Who Is Eligible?

Not everyone with obesity is eligible for gastric sleeve surgery. There are specific medical criteria that must be met. Let’s outline the main requirements:

Basic Criteria for the Procedure

The requirements include:

• Body Mass Index (BMI): must be 40 or higher, or 35 with associated medical conditions
• Age: usually between 18 and 65 years, though it may vary depending on the case
• General health: the patient must be able to tolerate surgery
• Lifestyle commitment: ability to follow a healthy diet and exercise routine
• Not pregnant: the patient must not be pregnant
• Psychological stability: ability to cope with post-surgical changes

Required Tests Before Surgery

Before undergoing gastric sleeve surgery, several medical tests must be performed:

• Laboratory tests: comprehensive blood tests and vitamin level measurements
• Cardiac tests: ECG and heart evaluation to ensure safety
• Endoscopy: to assess the condition of the stomach and esophagus
• Imaging: X-rays of the chest and abdomen
• Specialist consultations: with a nutritionist and a psychologist

Steps of the Procedure and What Follows

Understanding the stages of the procedure helps the patient prepare both mentally and physically. Here are the details from start to finish:

Surgical Procedure Stages

Gastrectomy is usually performed laparoscopically (without open surgery):

• General anesthesia: the patient is fully anesthetized
• Small incisions: typically 4–5 small openings in the abdomen
• Insertion of laparoscope: with a small camera and surgical instruments
• Stomach resection: the stomach is cut into a long tube shape
• Removal of the excised portion: the removed part is extracted
• Closure of incisions: closed with absorbable sutures

The procedure usually takes 60 to 90 minutes and requires high surgical expertise. At Dr. Abdullah Al-Munifi’s clinic, we use the latest bariatric and laparoscopic techniques to ensure the best results with minimal complications.

Recovery and Postoperative Period

Immediately after surgery:

• Hospital stay: usually 1–2 nights for monitoring
• Pain and discomfort: normal for 1–2 weeks
• Physical activity: light activities can resume after one week
• Return to work: typically after 2–3 weeks
• Intense exercise: after 4–6 weeks

Diet After Surgery

Following a proper diet is essential for the success of the procedure:

• First week: clear liquids only
• Second and third weeks: soft and pureed foods
• From the fourth week onward: normal foods in small portions
• Focus on protein: meat, chicken, fish, and eggs
• Avoid fatty foods and sweets: they may cause digestive discomfort
• Drink at least 2 liters of water daily

Expected Results and Health Benefits

Gastric sleeve surgery is known for its positive impact on overall health. Information about the procedure confirms that results begin within the first weeks and continue to improve over time.

Weight Loss and Expected Outcomes

Most patients achieve excellent results:

• Loss of 60–80% of excess weight within 18–24 months
• Results begin in the first month with a loss of 10–15 kg
• Stabilization: weight usually stabilizes after one to two years
