First steps

Our Centre of Laparoscopic Surgery's specialist obesity surgeons work together with our metabolic physician, bariatric nurse specialist, bariatric specialist dietitian and bariatric specialist physiotherapist to ensure that you receive appropriate specialist care and advice.

All our staff are experienced obesity specialists and they are enthusiastic to help patients reduce their weight in the most appropriate and safest way possible.

What is obesity?
Obesity is caused by consuming more calories than the body uses over a sustained period of time; this excess is stored in the body as fat. It is a chronic condition that can be difficult to treat.

There are many causes of obesity including metabolic, environmental, genetic, hormonal and a disordered relationship with food. Those who suffer with obesity are also more likely to develop a range of other diseases including diabetes, coronary heart disease, high blood pressure, sleep apnoea and early arthritis; which can only be managed by losing weight.

Is surgery for you

Advances in technology mean that surgeons can now make a person's stomach smaller, which reduces the amount that can be eaten at any one time.

There are two ways that surgery can help weight loss:

  • By decreasing food intake: surgeries include gastric banding, gastric bypass and sleeve gastrectomy. These limit the amount of food that can be held by the stomach. 
  • By causing food to be poorly digested and absorbed: such as the duodenal switch. This connects the stomach to a lower section of the small intestine, which means that the amount of calories absorbed into the body is decreased.

If you are obese and have been unsuccessful with other weight loss methods or you have an obesity-related disease, then surgery may be an option for you.

You may be eligible for surgery if you:

  • have a BMI (body mass index*) of 35 or more with an obesity-related physical problem such as diabetes, high blood pressure, sleep apnoea or early arthritis that could be improved with weight loss
  • have a BMI of 40 or more have failed to achieve or maintain clinically beneficial weight loss through non-surgical methods for at least six months (unless you have a BMI over 50, in which case you will go straight to surgery)
  • have a commitment to life-long follow up.

It is important that you consider all the options, and know the risks and benefits, before deciding to proceed with obesity surgery. At Homerton, you will have access to a range of professionals who will be able to discuss the other aspects of your healthcare such as nutrition, aftercare and physical activity.

What is the benefit of laparoscopic surgery?
We perform all our obesity surgery by using laparoscopy. Laparoscopic or 'keyhole' surgery avoids the need for a large incision, as in open surgey; instead the operations are performed through small incisions using long thin surgical equipment and video cameras.

This means that patients have minimal scarring, less pain and recovery times are much quicker.
