Weight Loss Surgery Aftercare

Our Weight Loss Surgery Aftercare Service is completed by two years of contact with your surgeon, specialist Bariatric Nurses and HCPC Registered Dietitian. This team will ensure you receive the care you need following your surgery and provide expert advice regarding recovery, including any necessary and advisable long-term dietary changes.

Gastric Sleeve Surgery

Typically performed laparoscopically, a sleeve gastrectomy involves removing around 80% of the stomach. The result is a tube or sleeve-like structure. The purpose of the gastric sleeve is to limit food intake, and you should expect a recovery time of 6 – 8 weeks with 1-2 weeks off work. 

The expected weight loss from the sleeve gastrectomy is up to 70% of your excess weight, as measured over a period of 2 years.

After surgery, the anatomy of the stomach will be permanently altered and you will require to change your diet in order to make a safe and effective recovery. Our dietitian will help you with this. 

Gastric Bypass Surgery

Allure Weightloss offer the traditional Roux-en-Y Gastric Bypass as well as the Mini-Gastric Bypass. These procedures are similar in nature and differ slightly (yet significantly enough) in the way in which they are performed by consultant surgeons. By limiting the available space inside your stomach, the bypass restricts food intake as well as the production of the hunger hormone, ghrelin. A bypass may be performed even if a patient has had the gastric sleeve in the past. 

Expected weight loss is up to 70% of excess weight.

Calculate Your BMI

How is body mass index (BMI) measured? 

An individuals BMI is calculated by using the following formula: 

BMI = Weight (kg) / Height (m)²

You must take your weight in kilograms, divide it by your height in meters, and then divide it a second time by your height in order to determine the correct body mass index. 

Not sure you qualify?

If you still aren’t sure, a member of our team will be able to help. If you are certain you won’t qualify for bariatric surgery, you may still be eligible for other medical weight loss treatments.

What is a Gastric Sleeve?

A gastric sleeve, or sleeve gastrectomy, is the process of removing up to 80% of the stomach in order to limit food consumption and reduce hunger hormones. Find out more about our gastric sleeve offerings

What is a Gastric Bypass?

The Roux-en-Y Gastric Bypass involves creating a smaller ‘pouch’ from your stomach and attaching it straight to your intestines, bypassing the main body of your stomach. 

What is Body Mass Index (BMI)?
The most widely used measurement for obesity. The BMI approximates body mass using a mathematical ratio of weight and height [(weight in kg ÷ height in meters) or (weight in pounds ÷ height in inches x 703)]. A BMI of 30 or more is regarded by most health agencies as the threshold for obesity. A BMI of 40 or more generally qualifies as morbid obesity. However, note that BMI measurements in body-builders and athletes may not be accurate determinants of obesity because the BMI does not distinguish between muscle and fat.
