Gastric Bypass Surgery

We’re the UK’s most trusted weight loss & cosmetic surgery provider

Meet your new weight loss partner.

Gastric bypass surgery is a life-changing procedure that could help you lose weight, improve your health, and transform your entire lifestyle. Gastric bypass may be suitable if you have a BMI of 40 or more (or less but not lower than 30), or a BMI of 35 or more and suffer an obesity-related condition such as Type 2 Diabetes. 

Losing weight on your own can be extremely difficult, and gastric bypass surgery is proven to be a highly-effective weight loss procedure when combined with diet, exercise, and a general lifestyle change. A gastric bypass procedure could help you lose an average of 55-70% of excess weight after three years, according to the 2014 National Bariatric Surgery Registry Report.

The surgery involves the creation of a small stomach pouch, to reduce the size of your stomach, and re-routing the small intestine. This assists weight loss by restricting food intake, reducing hunger and the absorption of calories and nutrients. A general anaesthetic is required for gastric bypass and depending on your medical condition and individual needs, the surgery can take between 2 – 3 hours.

Our expert team will explain the procedure and help you decide whether it’s the right route for you and your weight loss journey. Get in touch with us today to learn more about gastric bypass surgery.

After 2-3 months, most patients are back on a varied diet of solid food. However, some patients may struggle with certain textures of food such as bread or red meat. In addition, a phenomenon known as Dumping Syndrome can occur if too much sugar is consumed – this results in symptoms such as dizziness, sweating, palpitations and bloating. Often patients say that these symptoms help to discourage them from eating too much sugar, which can then enhance weight loss.

Gastric bypass details

We want you to make a fully informed decision before you go ahead with surgery, so we offer a private consultation at your local clinic free of charge. At your consultation, you’ll meet with a bariatric surgeon to discuss the weight loss options available and whether gastric bypass surgery is the most suitable procedure for your needs. You’ll be able to ask questions about all aspects of the surgery, from aftercare and dietary changes to the results you can expect. You’ll also meet your patient care coordinator, who will be with you every step of the journey. They will give you a personal quotation of costs and information about finance options, the expected timescale, our surgical facilities and door-to-door transport services.

At your consultation, you can book your surgery if you feel ready, but there’s no obligation to go ahead.Bariatric surgery is a big step and you may want to take time to do more research and think about your decision. We’ll give you a patient information booklet, which provides comprehensive information on your weight loss procedure, aftercare and dietary guidelines. This is an important resource and we require patients to read the detailed information it contains. You’ll also find lots of helpful information here on our website – you can read about our surgeons’ qualifications, THG’s weight loss management expertise and inspiring stories from some of our patients. Our patient care coordinators are available to discuss any concerns you may have. And when you feel ready, they can book you in for your procedure. We also have a 14-day ‘cooling off’ period in place, which means that if you change your mind about the procedure after booking within that period, you will not be charged.

On the day of your surgery, your medical team will make your experience as comfortable as possible and you’ll meet your surgeon again before the procedure. Gastric bypass surgery is carried out under general anaesthetic. There are several varieties of bypass, but all involve dividing the stomach to create a small stomach pouch and then attaching a section of the small intestine to the pouch, therefore bypassing part of the small intestine. The smaller stomach pouch restricts the amount of food you can eat, and is designed to make you feel full after smaller meals. It also aims to drop appetite hormone levels to reduce your appetite. Bypassing part of the small intestine reduces the amount of calories you absorb from food, as well as vitamins and minerals and so supplements are required for life. Gastric bypass surgery is non-reversible.
