Weight loss treatments in detail

Find out more about the weight loss treatments Ramsay Health Care offer:

Gastric Band

Gastric Band

Adjustable gastric banding / gastric bands (sometimes known as a lap band) is a restrictive Bariatric surgerical procedure.


A silicone band is placed around the upper part of the stomach, creating a small pouch above the band, that is about the size of a golf ball. This forms a large pouch below the band.

Gastric Bypass

Gastric Bypass

There are several variations of a Gastric Bypass. The most common procedure in the UK is the Roux-en-Y, also known as RYGB. It is a combination of restrictive and malabsorptive procedures, therefore has a two-way weight reducing effect.


A small pouch is created by stapling off a section of the upper part of the stomach. Below the staple line the stomach will remain but no food will enter here.

Gastric Sleeve

Gastric Sleeve

Gastric sleeve surgery is a restrictive procedure only. Two thirds of the stomach is resected and removed, leaving a smaller stomach in the shape of a sleeve.

The portion of the stomach removed produces a hormone that stimulates appetite and hunger. Removing this portion of stomach results in a significant reduction in appetite.

Gastric Balloon

Gastric Balloon

For many patients with a BMI (body mass index) of 27 - 35 surgery is not always available or recommended according to the NICE (National Institute of Clinical Excellence) guidelines, as patients with a lower BMI do not normally qualify for weight loss surgery.

The gastric balloon is a soft, expandable intragastric (inside the stomach) device that is temporarily inserted into the stomach.

Gastric Band Conversion

Conversion Surgery

Surgery patients are not always successful in reaching their weight loss goals.

Reasons for post-operative weight loss failure can include problems with the original surgery, as well as the patient’s inability to comply with necessary life style changes.
