Converting gastric band to gastric sleeve with The Hospital Group

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

Could conversion surgery help to boost or maintain your weight loss?

Most patients who have a gastric band fitted find that it’s all they need to reach their weight loss goals. However, some people decide to convert to a different procedure to overcome problems such as heartburn or band slippage or if you have not lost as much weight as you anticipated with the gastric band. It can help you to maintain the weight you have lost and, sometimes if required, lose more weight.

Converting a gastric band to a gastric sleeve may be a suitable option if your band needs to be removed for any reason or if you haven’t been able to achieve your weight loss goals. Gastric sleeve surgery is non-reversible, so you’ll want to make sure that it’s the right choice for you and take the advice of one of the leading bariatric surgeons that we work with.

Gastric sleeve surgery is generally suitable if you have a BMI of 40 or over, or less (but no lower than 30) if you have obesity-related conditions such as Type 2 diabetes. Conversion surgery is also considered in patients who have achieved significant weight loss in the interests of maintaining this loss. The surgery involves removing your gastric band, and then reducing the size and capacity of the stomach by about 75%, which includes removing the upper part of the stomach where the chemical that stimulates appetite (ghrelin) is produced. This helps to reduce appetite and the ability to eat large portions.

Gastric sleeve surgery can greatly aid weight loss when combined with a programme of dietary, exercise and lifestyle changes. Patients generally lose weight more rapidly than with a gastric band, helping them to achieve a more active lifestyle. On average patients lose 55 to 60% of excess weight after 3 years (source: National Bariatric Surgery Registry Report 2014). They also experience improvements in health conditions such as Type 2 diabetes, hypertension, sleep apnoea, asthma, joint pain, arthritis and fatigue, as well as feeling good about life again.

Converting gastric band to gastric sleeve FAQs

The gastric sleeve is more invasive than a gastric band, but less invasive than a gastric bypass. Itmay therefore suit patients for whom the bypass is inadvisable due to health complications. Usually, patients most suitable to have gastric sleeve surgery are those with a BMI of 40kg/m2 or over, although if your BMI is between 30kg/m2 and 40kg/m2 you may be considered, especially if you have an obesity-related condition such as Type 2 diabetes and even more so if you are from an Asian background (source: NICE clinical guideline 189, 2014). Conversion surgery is also considered in patients who have achieved significant weight loss in the interests of maintaining this loss. However, surgery is dependent on a bariatric surgeon’s opinion and your individual circumstances. All our weight-loss surgery patients have an in-depth consultation prior to surgery to discuss the most suitable procedure for them.

No. Like the bypass, the sleeve is a non-reversible procedure.

The sleeve works to reduce portion sizes, rather than specific food types. Compared to a gastric bypass, there are fewer restrictions on the types of food that patients can consume. However, some patients may struggle with certain textures of food such as bread or red meat.

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 sleeve 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 sleeve surgery is carried out under general anaesthetic and is usually carried out as keyhole surgery. First, your gastric band will be removed before proceeding with the gastric sleeve. The surgery involves vertical removal of up to 75% of the stomach area to leave a thin sleeve. The stomach continues to function as normal, but the smaller size restricts the amount you can eat and makes you feel full after smaller meals. It can also help to drop appetite hormone levels to reduce your appetite. Less stomach acid is produced, which can affect the absorption of some vitamins and minerals and so supplements are required for life. Gastric sleeve surgery is non-reversible.

We’ll be here throughout the recovery process to help you recuperate quickly. For gastric sleeve surgery you’ll normally need to stay in the hospital where your surgery has taken place for 2-3 nights. Each patient is given a personalised care plan, developed on the advice of their surgeon. All THG hospitals are equipped to the highest standards of clinical care and patient comfort.
