Gastric Sleeve Surgery: All your questions answered

Gastric Sleeve surgery, a bariatric procedure, permanently reduces the size of your stomach to limit food intake and decrease hunger hormones. You can expect to lose 70% of your excess weight within the first 12-18 months after the surgery.

Gastric sleeve surgery explained

What is a gastric sleeve?

Gastric sleeve surgery, also known as sleeve gastrectomy, is a permanent weight loss procedure. About 85% of the stomach’s volume is removed and the remaining bit is typically shaped like a ‘tube’ or ‘sleeve’. The aim of this procedure is to reduce the volume of food that the stomach can hold. 

Not everyone is eligible for gastric sleeve surgery. Typically, you need to have a BMI higher than 35 or a BMI higher of 30 with associated metabolic conditions such as type 2 diabetes.

Once you have had gastric sleeve surgery, you won’t be able to consume large amounts of food in one sitting. Your ‘new’ stomach only holds 200 ml of volume compared to a ‘normal’ stomach, which can typically hold about 1500ml. 

Generally, it is expected that a person could lose about 70% of their excess weight within a year to 18 months after the surgery.

Restrictive weight loss surgery

As you have a smaller stomach, you will feel full more quickly and therefore eat less, reducing calorie intake. 

Apart from the change in the size of the stomach, all other aspects of digestion remain unchanged – with food continuing through the stomach and into the intestines as normal, and nutrients being absorbed in the normal way.

That is why we call this type of surgery restrictive. It physically reduces the size of the stomach whilst the process of digestion, including the absorption of nutrients, remains the same. There is no rerouting of the digestive tract.

Hormonal changes contributing to weight loss

Gastric sleeve surgery also impacts the production of hunger hormones. After the procedure these hormones typically decrease. As a result, you have a reduced appetite. 

Gastric sleeve surgery benefits

Why is this procedure so effective?

Sleeve gastrectomy is considered effective for multiple reasons:

  • Decreased stomach size: You feel full after consuming small portions, reducing overall calorie intake
  • Changed hunger hormone levels: The procedure can decrease hunger hormone levels, leading to a reduced appetite and helping with weight loss
  • Lifestyle changes: After surgery you work with our Peak dietitians to develop a healthier eating and activity plan
  • Improvement in metabolic conditions: The procedure can lead to improvement or resolution of obesity-related metabolic conditions.

Should I have gastric sleeve or gastric bypass surgery?

Gastric bypass is another weight loss procedure that is performed at Core Specialists Group. It’s a procedure that is both restrictive (similar to sleeve) and malabsorptive. Whether you have gastric sleeve or gastric bypass surgery depends on a range of factors that we have summarised here.

Laparoscopic Sleeve Gastrectomy explained

Laparoscopic sleeve gastrectomy is performed under general anaesthetic. During this procedure, we make a few small incisions in the abdomen. We use one of these keyholes to insert the laparoscope, a thin tube with a camera at the end. This allows us to view the procedure on a screen. 

Then we insert surgical instruments through the other incisions. They allow us to reduce the size of your stomach. The remaining part is a tubular pouch that resembles the shape of a banana.

Once the stomach is reduced in size, we close the small incisions with stitches or staples. The entire procedure takes between one to two hours.

You may have heard about the Peak surgical weight loss program. This program has been developed by Core-specialist Dr Candice Silverman in consultation with a team of dedicated health professionals. 

The Peak program has been designed to help you win your battle with obesity. We will support you throughout your weight loss journey and our aim is to get you in ‘peak’ condition, both physically and mentally.

Peak is about surgery, dietetics and psychology. There are many factors contributing to weight gain. Addressing psychological, emotional and behavioural challenges, prepares you for the journey you’re on as well as contributes to optimal outcomes. You will see a Peak dietitian and psychologist before and after surgery.
  • Your Peak dietitian will help you prepare for the drastic changes. They will guide you on what foods to consume for optimal nutrition and how to avoid complications, both before and after surgery.
  • After surgery, it will be impossible to consume large meals. Your Peak dietitian will advise you to eat 4-6 smaller meals every day. When you follow these guidelines you can expect to lose around 65% of your excess weight within a year.
  • Your Peak psychologist will provide emotional support and prepare you mentally for the changes that are about to happen.
  • Both the dietitian and psychologist play a role in facilitating necessary behavioural changes, as weight loss surgery is not a ‘quick fix’. Lifestyle changes are required and this may be challenging.
