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.

How to get a gastric bypass: Your journey step by step.
Your first appointment
At The Hospital Group, it all starts with a telephone consultation, during which you'll have the chance to talk to one of our friendly surgeon assistants. Our consultation will include the reasons you're interested in gastric bypass surgery, how much it'll cost, the finance options which are available to you, and how much recovery time you’ll need. We'll also discuss potential surgery dates. Whenever you decide to book a surgery date, you can secure it for a minimum refundable deposit of £500.
The next step after this is to book a free weight loss consultation with our specialists.
All weight loss surgery involves two specialist consultations. The first is with a dedicated weight loss expert – either a nurse or dietitian. You can visit your local clinic, or we can carry it out via video chat. This first consultation will let us find out more about your weight loss goals and your medical history, and help us to determine if surgery will be the best course of action for you.
The consultation will also consider the results you both expect and hope to see, plus any risks and complications involved. You can trust our specialists to be extremely knowledgeable about your gastric bypass surgery, and they will answer any questions that you might have.
Happy to go ahead? You'll then have a consultation with your expert surgeon. The benefits and risks will again be explained, and your surgeon will also confirm if surgery is the right option. You'll then be referred to a clinic nurse for the assessments and tests needed before your procedure.
The gastric bypass procedure
Before the day of your operation, you'll be told about the specifics of the surgery, such as how long the procedure typically takes, and the types of anaesthetic used. The entire procedure itself is also explained to you at this point, so that nothing will ever be a surprise to you.
On the day of your gastric bypass, you'll meet your surgeon to discuss any final questions and you'll read through your consent form. You'll also have the chance to meet your surgical team before you go into theatre for your procedure.
You'll need to stay in hospital during the initial stages of your gastric bypass recovery, and it's not uncommon to feel swollen and in some pain. You don't have to worry, though - you'll have our friendly nursing team on hand to look after you and provide any painkillers you need.
Immediately following the operation, you'll be given intravenous drip hydration in order to maintain your fluid levels. You'll also need someone to drive you home when you're discharged, as the surgery is performed under general anaesthetic and its effects may take a while to wear off.
Rest assured that we'll take you through how best to take care of yourself once you're back at home. We have a 24/7 helpline, too, meaning that a member of the clinical team will be available for you to call for support at any time.
The gastric bypass is only part of your weight loss journey, and it's important to us that we stay with you every step of the way afterwards. That's why we offer the highest standards of aftercare and have a range of different packages available to support your ongoing weight loss. These can be discussed during your consultation.
No matter if you’ve had a mini or Roux-en-Y gastric bypass, your body will need time to heal afterwards. You will need to stay off work until you feel ready to return, and it's important to avoid any heavy lifting or strenuous activity for around six weeks. As every person is different, it may take you more or less time to fully recover.
