Gastric bypass surgery is a procedure that can help you to achieve long term weight loss. It can be an effective solution for anyone who has tried many other methods of diet and exercise, yet still has a body mass index (BMI) of 30 (or above).
This procedure can take different forms, but one of the most popular in the UK is called a Roux-en-Y gastric bypass. The goal of each procedure is always the same - reducing the size of your stomach, which restricts how much you can eat. A gastric bypass also affects your hunger and appetite levels.
An alternative procedure to the Roux-en-Y gastric bypass is a mini loop gastric bypass. This is a newer type of bypass which works in much the same way and offers the same benefits. The key difference is that a mini gastric bypass will involve less 'rerouting' of the digestive system.
In a gastric bypass operation, your digestive system is rebuilt to change how your stomach and intestines manage your food intake. A smaller pouch is created in the top part of your stomach, which leaves a larger pouch in the lower part of your stomach that will no longer be used.
In essence, this procedure makes the stomach smaller. The smaller pouch is connected to your small intestine by a small tunnel created by your surgeon – 'bypassing' the rest of the stomach. The food you eat after a gastric bypass also misses out the first section of your small intestine.
The difference between a Roux-en-Y and a mini gastric bypass is in the number of anastomosis (or joins) between the stomach and bowel. A Roux-en-Y gastric bypass has two of these 'joins' – upper and lower. A mini bypass will have just one and misses out more of the small intestine.
In both procedures, you'll experience an increase in hormones that make you feel satisfied. At the same time, the hormones that make you feel hungry will be reduced, which will reduce your overall appetite too. As a result, a gastric bypass can help you lose weight safely and effectively over time.
Gastric bypass surgery can help you achieve your long-term weight loss goals. The third 2020 National Bariatric Surgery Register study found that, on average, a person can lose more than 70% of excess weight within one year of surgery.
If you decide to have gastric bypass surgery, you might find that substantial weight loss leads to better mobility, an increase in energy levels, and a number of improvements to your quality of life. This can include a wider choice of clothing that would've previously felt uncomfortable.
A gastric bypass may also help with a number of weight-related health issues. Type 2 diabetes and hypertension are among the conditions that are known to be improved with gastric bypass surgery. Every patient is different, but this is something we can discuss with you.
Once you start to see the results from your procedure, you might be able to live a more active lifestyle with your family and friends. And you may also feel more confident in social situations because of your slimmer body.
There are risks involved with all surgical procedures. If you believe that gastric bypass surgery could help you, it's also important you know what the risks are before you go ahead. By doing so, you can weigh up those risks against the benefits your procedure could bring.
We want your decision to be made based on all the facts, and so we'll discuss all the potential risks of a gastric bypass during your consultation. You can also ask any questions you might have.
In some cases, gastric bypass side effects can include bleeding, infection, pain, scarring, or reflux.
This procedure could be the answer to shedding your excess weight and living a healthier life. It's not for everyone, but you might be suitable if you suffer with obesity, have a body mass index (BMI) of 30 or over, and tried to lose weight in other ways that haven't worked.
We may also be able to offer you gastric bypass surgery if you have an existing medical issue linked to weight, although you must be prepared to change your lifestyle too. This means following the advice of our dietitians, for example, and making healthier food choices in future.
It'll also help is you engage in regular planned exercise after surgery to achieve, and maintain, your weight loss results. The impact of a gastric bypass can be life-changing, and our expert surgeons can advise you on whether you're a suitable candidate during your consultation.

Your journey with The Hospital Group begins with a telephone consultation with our friendly surgeon assistants. During this conversation you can talk through why you’re interested in surgery, how much it costs, the finance options available to you, how much recovery time you’ll need, and potential surgery dates. Whenever you decide to book a surgery date, you can secure it for a minimum refundable deposit of £500.
If you would like to proceed, we will book your free weight loss consultation.
During the consultation with your surgeon, you will talk about your goals for surgery and go through your medical history to ascertain whether you are a suitable candidate for this procedure. You will also discuss the results you might expect, as well as the possible risks and complications of surgery. You will then be referred to a clinic nurse for pre-operative assessments and tests and a dietitian for discussion and advice on the pre- and post-operative diet.
You will meet your surgeon on the day of your surgery so that you can talk through any final questions you might have and read through the consent form. The whole surgical team will be introduced to you before heading into theatre for the procedure.
The specifics of surgery will be discussed prior to the day – you will find out how long it will take, the types of anaesthetics used, and they will talk you through the procedure itself.
Following weight loss surgery, you will need to stay in hospital for the initial stages of your recovery. You will likely feel swollen and in some pain following the procedure. Our friendly nursing team will be on hand to look after you and provide any painkillers you might need.
Immediately after surgery, you will be given intravenous drip hydration so that your fluid levels are maintained. The procedure is carried out under general anaesthetic, so you will need to arrange for someone to drive you home when you are discharged. We recommend that you have someone with you until the effects of the anaesthetic wear off.
We will talk you through taking care of yourself at home before you leave hospital. There is also a 24/7 helpline available to you where you can call a member of the clinical team at any time for support.
The surgery itself is only the beginning, and we believe in the highest standard of aftercare following your procedure. Your body needs time to heal, and you will need to stay off work until you feel ready to return. You should also avoid any heavy lifting or strenuous activity for around six weeks. Recovery periods can be discussed with your surgeon before the procedure.
There are a number of different aftercare packages available to help aid you in your weight loss journey and these will be discussed during your consultation process. You can read more about these on our aftercare page.
