What is Weight Loss Surgery?

Persons who have struggled with their weight and have had failed attempts at weight loss through diet and exercise may be candidates for weight loss surgery. Weight loss or bariatric surgery can help to facilitate weight loss by two methods:

  1. Reducing how much can be eaten
  2. Reducing the amount of calories that are absorbed by the intestine.

There are quite a few surgical procedures that have been developed over the last few decades, the most popular being gastric bypass, sleeve gastrectomy and gastric banding.

What is a sleeve gastrectomy?

A sleeve gastrectomy or gastric sleeve is a surgical procedure performed in patients who are significantly overweight (morbidly obese). The aim of the surgery is to assist these patients in losing weight by restricting the amount they can eat. In addition to weight loss, the procedure can assist in reducing the need for medications for hypertension and diabetes.

The procedure involves removing 80-85% of the stomach. The appearance of the stomach following surgery is like a tube or “sleeve”. In addition to restricting the amount the patient can eat, the desire to eat is greatly reduced as the section of the stomach that produces “the hunger hormone” is removed.

The procedure is performed laparoscopically, using small incisions and video camera equipment. This ensures faster recovery and shorter hospital stay as postoperative pain is minimal.

Sleeve Gastrectomy vs. Gastric Bypass

Sleeve gastrectomy is one of the newer surgical weight loss procedures. Gastric bypass has long been considered the gold standard for weight loss surgery. It involves reducing the size of the stomach but also bypasses a long portion of the intestine to reduce absorption. This process is effective in reducing the absorption of calories absorbed. However, it has a significant impact on the absorption of essential vitamins and minerals. This can greatly affect a patient’s well-being. As such, patients require constant monitoring for deficiencies in vitamins and minerals and often require lifelong medications and supplements. Patients undergoing sleeve gastrectomy do not require lifelong supplementation or constant tests.

Newer studies have shown that sleeve gastrectomy and gastric bypass are equally effective in excessive weight loss.

Is Weight Loss Surgery For You?

Happy weight loss surgery patient

Weight loss surgery involves a process of assessment and preparation prior to undergoing the procedure. It is very important to ensure that you are the right candidate for the procedure, that the procedure has the best chance of being effective and that you are prepared mentally, physically, psychologically and emotionally for the changes that are about to occur. Candidates for sleeve gastrectomy are persons with a body mass index greater than 40 or body mass index greater than 35 in persons with conditions such as hypertension, diabetes and obstructive sleep apnoea.

Knowing your BMI

Body Mass Index, or BMI is the customary method used to measure obesity. It’s a calculation of your weight-to-height ratio and can provide insight into risk for diseases.

What to expect:

  • All potential candidates require psychological assessment to assess the factors that have contributed to weight gain and to ensure that all modifiable factors are addressed prior to the surgery. In addition, this period allows for the understanding of the changes that would be expected after the surgery
  • All potential candidates must demonstrate a commitment to weight loss as this commitment has been found to continue after surgery. This includes the demonstration of commitment to a diet plan, exercise regime and demonstration of some weight loss prior to surgery
  • All pertinent medical information will be reviewed by our bariatric surgeon, including medical and psychological assessments, if already done. If the necessary assessments have not been done, we can arrange for our partnered physicians to do so through video and telephone conferencing
  • You will be admitted to hospital on the day prior to the procedure and remain in hospital for 1 to 2 days
  • Your diet will be altered significantly after the procedure. It will take about 4 weeks to progress from liquid diet to solid foods
