Obesity & Weight loss surgery
Weight loss surgery is widely endorsed throughout the NHS and recommended in the national (NICE) guidance. Mr John Saunders is an established Bariatric Surgeon working at the regional NHS Bariatric Surgery Centre at Salford Royal Hospital, where he performs weight loss surgery routinely and delivers the emergency bariatric service.
Are you considering weight loss surgery ?
Obesity is measured using BMI, Body Mass Index, and if greater than 30 then your weight is considered obese. Obesity can lead to a wide variety of serious medical problems, such as stroke, cancer and diabetes, and also markedly reduced life expectancy.
Many overweight patients will have tried losing weight over a number of years using various diets, however weight-loss (bariatric) surgery is the only treatment that gives effective long term weight loss.
Bariatric weight loss surgery has been shown to improve and reverse many of these associated serious medical problems such as diabetes, high blood pressure, sleep apnoea, asthma, reflux and risk of cancer and stroke.

The Team
Weight loss surgery is delivered by a multi-disciplinary team of Bariatric specialists including your surgeon & anaesthetist.
You will have close contact with the Bariatric specialist nurse and specialist bariatric dietician, both before and after your operation.
You may also see a specialist psychologist, physiotherapist, pharmacist and bariatric physician, depending upon your needs. This team will provide different aspects to your care along your weight loss journey, and will support you at every step, to help you achieve your goals.
gastric Sleeve
A sleeve gastrectomy is performed by stapling the stomach along its entire length and converting the stomach from a wide storage bag into a long thin tube.
This removes around 75% of the stomach, including the part where the hunger hormone ‘Ghrelin’ is produced. This significantly reduces both the amount of food you can eat and the hunger hormone levels, promoting excellent excess weight loss.
The sleeve gastrectomy is a popular choice as it does not disrupt gut continuity, whilst bringing excellent weight loss and resolution of associated medical problems, comparable with the gastric bypass.
gastric Bypass
Gastric bypass surgery divides the stomach with a stapler leaving a small upper pouch, which is then connected to the small intestine below. In addition to reducing the capacity of the stomach and reducing your appetite, the food bypasses the main body of the stomach and part of the upper small intestine, so that fewer calories can be absorbed from the food eaten.
Bypassing the upper small intestine also has a powerful effect on the gut hormones both helping weight loss and improving weight related medical conditions like diabetes.
The gastric bypass can be performed as a one anastomosis (the OAGB or mini-bypass) or two anastomosis (Roux-en-Y gastric bypass) procedure. With only a single anastomosis the OAGB is more popular, but there is a small risk of suffering from bile reflux. The RYGB is the most traditional weight loss operation and is particularly helpful for those with uncontrolled acid reflux. Both operations produce similarly excellent weight loss (greater than sleeve gastrectomy in the longer term) and are highly effective at treating metabolic conditions such as diabetes or high blood pressure.
gastric balloon
A gastric balloon is placed in the stomach and then inflated. It reduces the stomach capacity and provides a sensation of fullness after eating even small meals.
This acts as a temporary weight loss tool as they are subsequently removed endoscopically after 6 or 12 months. Balloons can be placed and removed without general anaesthetic under sedation only. You can consider this procedure if you are simply overweight (from BMI 27), rather than obese, as it is easily reversible and the ‘excess weight loss’ is not as marked as surgery.
gastric band
A gastric band is inserted using a laparoscopic key hole operation to place a small inflatable silicone band around the upper part of the stomach.
This creates a new smaller pouch which can hold significantly less food. The band also slows down the passage of food from the pouch to the rest of the stomach. This makes you feel full faster and reduces food consumption. The band can be inflated or deflated by a qualified specialist, providing more or less restriction as required.
Less bands are placed in recent years as other more effective weight loss procedures have been developed which are more reliable in the longer term.
