Bariatric (or weight loss) surgery is the name for a group of surgical procedures that can help to treat excess weight, by making changes to the digestive system.

 

Here, Mrs Kalpana Devalia, leading consultant general, gastrointestinal and bariatric surgeon, provides an expert insight into bariatric surgery. She explains what are the main operations performed, who is a suitable candidate and how results can be maintained, among other important points.

 

 

What surgical options exist to help people with obesity lose weight?

 

There are two main surgical operations which are offered worldwide to help patients lose weight: sleeve gastrectomy and gastric bypass surgery.

 

Both of these operations are extremely safe and are both performed using a minimally invasive (keyhole) technique, which helps with reduced post-operative discomfort and early recovery.

 

Who is a candidate for these surgeries?

 

To assess who is the best candidate for weight loss surgery, there is a guidance to follow, which depends on the patient's body mass index (BMI). This involves a simple equation that is calculated by dividing a patient's weight in kilograms divided by squaring their height in meters.

 

The equation may seem a bit complicated, but it is very simple and there are BMI calculators available online for people to calculate their BMI. Classification for BMI is as follows:

  • A BMI between 18.5 to 24.9 kilograms per meter square is classed as normal
  • A BMI greater than 25, but under 29.9 kilograms per meter square is classed as overweight
  • A BMI over 30 is classed as obesity
  • A BMI of about 40 is classed as extreme obesity or severe obesity

 

Patients who would be eligible to have bariatric surgery are:

  • Patients who have extreme obesity
  • Patients who have severe obesity
  • Patients who have obesity with a significant co-existing medical condition that is directly related to their obesity, such as type 2 diabeteshypertensionasthma or sleep apnoea

 

Do the results of these surgeries usually last?

 

The results of weight loss surgery are expected to last for decades, but it is extremely important that these patients follow a healthy diet, make all the lifestyle changes required in terms of maintaining their weight loss, and also have a structured exercise program to follow.

 

Are there any risks to these types of surgery?

 

Weight loss surgery is a major operation, but it is extremely safe and the risks are low. The risk of mortality is comparable to a gallstone operation or a knee operation, for example, which are very common operations with very low risks.
