Bariatric Surgery

Gastric Bypass | Gastric Sleeve

Bariatric Surgery with Allure Weightloss

Dedicated to treating our patients like people, Allure Weightloss facilitate gastric sleeve and gastric bypass surgeries in the United Kingdom. These two traditional methods of weight loss surgery are trusted by patients and healthcare professionals globally, changing people’s lives for the better, and reducing the comorbidities associated with obesity. Any bariatric surgery is distinctly different to a gastric balloon placement, the latter being a temporary weight loss device.

What is Bariatric Surgery?

Bariatric surgeries hold the aim of reducing patient food consumption and encouraging weight loss by removing, limiting, or bypassing part of the stomach. The treatments we provide that fall under the umbrella of bariatric surgery include the Sleeve Gastrectomy and Roux-en-Y Gastric Bypass. They are an option for those struggling with obesity and co-morbidities, having already attempted more traditional methods of weight loss. 

Alongside weight loss surgery, the patient will be supported to make the necessary dietary and lifestyle changes in order to properly maintain weight loss. This aftercare support will last up to 2 years. 

We have currently hold private surgeries in the North West, Midlands, and South East of England.

Bariatric Surgery should be carefully considered with all relevant information available. Our consultants and nurses can help. 

What is a Sleeve Gastrectomy?

Typically performed laparoscopically (camera guided medical instruments are inserted through multiple small incisions in the upper abdomen), a sleeve gastrectomy involves removing a large part of the stomach in order to reduce it to about 15% – 20% of its original size. The result is a tube or sleeve-like structure. As you might expect, the purpose of the gastric sleeve is to limit the food intake of the individual post-procedure, and you should expect a recovery time of several weeks, with 1-2 weeks off work.

The expected weight loss from the sleeve gastrectomy is up to 60% of your excess weight over a period of 2-years.

What is a Roux-en-Y Bypass?

The Roux-en-Y Bypass, or bariatric bypass surgery, involves creating a small pouch out of the stomach and attaching it straight to the small intestine, removing your ability to consume as much food. This process of bypassing a large part of the stomach is permanent and will require a lifestyle change, particularly around your diet, in order to support the process. This procedure is conducted to help patients lose weight and reduce the risk of life-threatening weight-related health problems such as heart disease, high blood pressure, and high cholesterol.

The expected excess weight loss from the Roux-en-Y Bypass is up to 70% over a 2 year period. With a recovery time of 6 – 8 weeks, you will need 2 – 3 weeks off work.

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.

The most common risks associated with bariatric surgery include:

  • Chronic nausea and vomiting
  • Acid reflux
  • Inability to eat certain foods
  • Obstruction of stomach
  • Anesthesia-related risks
  • Dilation of esophagus
  • Infection
