Sleeve Gastrectomy: A Comprehensive Guide to Weight Loss Surgery

In the fight against obesity, a lot of people look for practical, long-term ways to lose a lot of weight and become healthier overall. With encouraging outcomes, sleeve gastrectomy has become a popular surgical weight reduction technique.

A big section of the stomach is surgically removed during a sleeve gastrectomy in order to form a smaller, banana-shaped stomach pouch. By limiting the quantity of food that can be taken at once, this innovative stomach pouch helps people lose weight. We will provide a thorough explanation of sleeve gastrectomy in this post, along with its description, prerequisites, procedure, and aftercare.

What is a Sleeve Gastrectomy?

The sleeve gastrectomy, completed within a couple of hours while under general anaesthesia, is a surgical procedure that involves the use of a laparoscope to remove a substantial portion of the stomach through several small abdominal incisions. Finally, the remaining stomach is stitched into a small banana-shaped pouch.

What Are The Benefits of Sleeve Gastrectomy?

There are several advantages to a sleeve gastrectomy for those who are battling obesity and associated medical issues. The following are a few of the main advantages of sleeve gastrectomy:

Significant Weight Loss

Sleeve gastrectomy has been proven effective for lasting weight loss, with a loss of 50-70% of excess weight achievable within two years. It also brings the potential for improved health and lowered risk of obesity-linked issues like sleep apnoea, diabetes, and hypertension.

Improved Metabolic Health

By reducing insulin resistance, boosting glucose control, and decreasing blood pressure and cholesterol levels, sleeve gastrectomy can heighten metabolic health considerably. The after-effects? The risk of cardiovascular disease and type 2 diabetes is plummeting.

Reduced Hunger and Appetite

The hormone ghrelin, which promotes hunger, may be produced less often as a result of the sleeve gastrectomy’s reduction in stomach size. Patients may, therefore, feel less hungry and more satisfied, which will make it simpler for them to stick to a balanced diet.

Improved Quality of Life

With a sleeve gastrectomy, patients’ lives can be greatly transformed. It can boost self-esteem and confidence, as well as enhance mobility, physical activity, and overall well-being.

Minimally Invasive Procedure

As a minimally invasive procedure using laparoscopic techniques, sleeve gastrectomy is often conducted with several advantages over old-school open surgery. For instance, the technique calls for less scarring and fewer incisions. Moreover, patients have shorter stays at the hospital and faster recovery times.

Reduced Risk of Complications

Comparing sleeve gastrectomy to other weight reduction surgeries like gastric bypass surgery, the former has a reduced chance of complications. The method minimises the risk of problems like malabsorption and dumping syndrome since it does not entail rerouting or reconnecting the intestines.

Who Is Eligible for Sleeve Gastrectomy?

For sleeve gastrectomy candidacy, patients require extensive medical assessment. A body mass index (BMI) score of 40 or higher, or a BMI of at least 35 with obesity-linked ailments such as hypertension or diabetes, are commonly qualifying factors.

What Can You Expect From The Procedure?

Step 1: Pre-operative Preparations

To confirm their eligibility for surgery, patients must pass multiple exams and testing. These tests may include laboratory work, imaging scans, and consultations with various professionals, such as dieticians or psychologists. The therapy preparation process involves detailed instructions for patients on how to take their medications correctly and modify their food choices.

Step 2: Anaesthesia

The anaesthesiologist will carefully observe the patient’s health and safety during surgery while making them feel calm and sleepy by administering general anaesthesia as soon as it is deemed appropriate.

Step 3: Making Incisions

To get to the stomach, the surgeon will make a number of tiny incisions in the abdomen. Usually less than an inch long, these incisions are positioned carefully to reduce scarring and encourage healing.

Step 4: Removing a Portion of the Stomach

The surgeon will delicately remove a big piece of the stomach using a laparoscope, leaving behind a smaller pouch that resembles a banana. The specific requirements and objectives of each patient determine how much of their stomach is removed.

Step 5: Stapling the Remaining Stomach

After that, a smaller, more constrictive stomach pouch is made by stitching the remaining stomach together. There will be no need to remove the permanent staples utilised in this treatment.

Step 6: Closing Incisions

Using surgical glue or sutures, the physician will seal the incisions following the procedure. Patients can expect slight discomfort or tenderness at the incision sites for a few days post-procedure, though these symptoms quickly subside.


The long-term success of patients undergoing sleeve gastrectomy, a procedure with a high success rate, involves comprehending its entirety along with required lifestyle changes and potential risks. This surgery improves metabolic health and eliminates obesity-related comorbidities. It has been a boon for many people seeking significant weight loss.
