Bariatric Surgery in London

 

Having bariatric surgery is a big step, but it can help you to lose weight that you haven’t been able to shift through diet and exercise alone. Getting rid of that excess weight could have a big impact on your health, so it is important to consider all of the tools that are available to help you. If you are struggling to lose weight, it may be time to consider weight loss surgery. You can talk to a doctor at the weight loss clinic in London about what the procedure will involve and whether it is the right choice for you.

 

Is Weight Loss Surgery Right for You?

 

Weight loss surgery isn’t right for everyone and it is a serious procedure, so you need to be sure that you will benefit from the operation. If you have not been able to successfully lose weight with the aid of diet, exercise and medications, weight loss surgery is a suitable treatment option when you have a high body mass index. Indeed, according to the National Institute for Health and Care Excellence, bariatric procedures are recommended if you have a BMI greater than 40, or a BMI greater than 35 with obesity-related complications such as type 2 diabetes or heart disease(1). In cases where your BMI is over 50, surgery to enable weight loss can even be initiated as a first line option for treatment owing to the risks your excess weight poses to your health. While bariatric surgery doesn't offer a quick fix and you will need to demonstrate that you are committed to making lifelong changes and attending regular follow-up, you can achieve significant weight loss when you adhere to the lifestyle advice given after your operation. For instance, with a gastric band a weight loss of one to two pounds each week is achievable for around 18 months, while you will lose weight more quickly if you opt for a gastric bypass(2).

 

What Types of Bariatric Surgery Are Available?

 

If you think that weight loss surgery might be the right option for you, it is important to learn more about what it will involve so that you can make an informed decision. You need to know what will happen during the operation and how it will help you to lose weight. It is also important to consider the potential risks of the operation as well as the benefits.

 

There are three main forms of surgery for weight loss performed in the UK, which are an adjustable gastric band, gastric bypass and sleeve gastrectomy. Although further details of each type of operation performed by Mr Sanjay Agrawal are available on the website, the basics of each procedure are provided below:

  • Adjustable gastric band. This laparoscopic procedure involves positioning an inflatable band around an upper section of your stomach to form a small pouch and a narrow channel that leads to the remainder of your stomach. A thin tube connects your band to an access port just beneath your skin and injecting fluid into the access port changes the size of your gastric band. The result of this bariatric surgery is that it reduces the amount of food entering your stomach and reduces your appetite. A smaller dietary intake aids weight loss and it is typical to lose 50% of your excess weight with a lap band. However, as with any form of surgery for weight loss, for best results you will still need to limit your intake of energy dense foods and fluids.

  • Gastric bypass. As with a gastric band this laparoscopic operation reduces the size of your stomach to a small pouch, but at the same time this type of bariatric surgery bypasses a section of your small intestines. As a result you will not only experience early satiety and reduced appetite, but you will also absorb less energy from the food you eat. The extra calorie deficit created by reduced absorption means that it is usual to lose between 60 and 70% of your excess weight after this procedure, though you may also experience symptoms of reduced absorption as well.

  • Sleeve gastrectomy. This newer laparoscopic surgery reduces your stomach size by removing a section of stomach tissue to leave a long, thin stomach tube. You will feel fuller quicker after eating and experience reduced appetite, both of which enable you to lose between 50 and 60% of your excess weight.

Which Bariatric Surgery Option Is Best?

 

If an assessment shows that you are a suitable candidate for a surgical procedure to aid weight loss, you will need to choose which type of surgery best meets your needs. While this is often a difficult decision to make, discussing the pros and cons of each type of bariatric surgery for your circumstances with Mr Agrawal will help you to make an informed decision. It is also important to appreciate the risks associated with weight loss surgery, as like any operation there is the potential for adverse effects to occur, and the anaesthetic risks are greater with a higher BMI. However, the benefits and risks are weighed up by Mr Agrawal so that he will only offer you a surgical procedure that he is confident is safe for you to undertake. Encouragingly, only a very small proportion of patients experience any major complications after a gastric band, gastric bypass or gastric sleeve operation, so you can feel reassured about opting for weight loss surgery to allow you to meet your long-term goals.

 

What Happens After Weight Loss Surgery?

 

If you decide to go ahead with the bariatric surgery, you will receive plenty of support to help you to make it a success. The experts at the clinic will help you to come up with a diet and exercise plan before you undergo the procedure. Following this personalised plan should help you to recover from the surgery and to achieve your weight loss goals. You will need to be very careful about what you eat, but the effects of the bariatric surgery should make sticking to your diet a little easier. You should feel full faster, which should help you to eat less. Depending on the kind of procedure you have had, you may also have a reduced appetite or an aversion to sweet foods. You should find dieting much easier when you aren’t feeling empty or hungry after your meals.

 

Reaching your target weight will be an important milestone after the surgery, but when you undergo a bariatric procedure you need to be committed to making long term changes. You should keep eating well and looking after yourself so that you stay healthy and keep the weight off. The surgery is not the end of your efforts to lose weight and improve your health. It is the beginning of a new lifestyle that should last you forever.

 

If you need help to lose weight and you are ready to make lifelong changes, make an appointment at the London Obesity Clinic to find out whether bariatric surgery is right for you.

 

How Can Bariatric Surgery Help?

 

Bariatric surgery can help you to lose weight. It won’t do the hard work for you, but it can help you to stick to your diet. Different types of weight loss surgery offer different kinds of help. However, it will still be up to you to eat well and exercise.

 

How Bariatric Surgery Works

 

There are three different types of bariatric surgery. You can have a gastric band, a gastric bypass, or a sleeve gastrectomy. All three of these procedures can help you to eat less. You won’t be able to fit as much in your stomach after the operation. You should end up eating less at each meal, but you will still feel full. Sticking to your diet will be easier when you can’t eat as much.

 

A gastric bypass also helps in another way. It changes the path food takes through your digestive system. This can help you to lose weight. The food is diverted past a section of your small intestine. You will absorb fewer calories from the food that you eat. The gastric bypass can also make it easier to avoid sweet foods. You might start to feel ill if you eat too much sugar.

 

Losing Weight after Bariatric Surgery

 

Weight loss surgery will make dieting easier, but you will still have to work hard. You will need to make long term changes to lose weight. Knowing what a big step you have taken can help you to stay motivated. The support you receive from your doctor will also help.

 

Your doctor will provide lots of advice before the bariatric surgery. You will be given a diet and exercise plan to follow. The weight loss surgery will make it easier for you to stick to this diet. You have to take in fewer calories than your body uses up. You will need to eat a balanced, low calorie diet. You should avoid foods and drinks that are high in fat or sugar.

 

You will also get advice on your eating habits. It is best to eat several small meals at the same times each day. Eating slowly and stopping when you feel full will help too. You should also get plenty of exercise. You should be able to get more active as you lose weight. You should aim to develop new habits that will last a lifetime. You will still need to eat well when you reach your target weight.
