Who is a gastric sleeve intended for?

A sleeve gastrectomy offers a solution for overweight people. Especially people who’ve already tried various diets but who fail to lose weight are suitable candidates.

Are there any other gastric sleeve conditions besides being overweight? Your body must be in a good condition to be able to recover. Of course, we will always discuss your options in detail and assess your health status to see whether a gastric sleeve operation is a suitable solution for you and your weight problem.

Gastric sleeve: the procedure

A sleeve gastrectomy is a common weight loss procedure. The operation is extremely safe and effective. The operation takes 1 to 2 hours and is performed under general anaesthetic.

During the procedure we reduce the stomach to the shape of a sleeve, which explains the name gastric sleeve. Only four one-centimetre incisions and one five-centimetre incision are made in the abdomen. We use staples to create this smaller stomach.

Continuity to the oesophagus and small intestine is preserved, as is the sphincter at the transition from the stomach to the small intestine. The part of the stomach that remains is less stretchy. As a result, the stomach will empty less quickly and no dumping syndrome can occur.

This intervention mainly ensures that the amount of food you can take in during a meal is greatly reduced. All this without feeling hungry and feeling satiated for longer. And everything you eat is also digested. So no nutritional deficiencies can occur.

After the procedure, you will stay overnight at Wellness Kliniek so we can keep a close eye on you. We’ll apply 5 post-operative adhesive plasters as a bandage. You need to take it easy for the first three to six weeks after surgery. The largest part of your recovery will be in the first two weeks. The recovery period can differ from person to person, but we will of course guide and advise you personally.

What to expect?

The results of a stomach reduction are often spectacular. You will start eating less, so you will eventually lose 70 to 80% of your excess weight. The big advantage of a gastric sleeve is that your feeling of hunger subsides, so losing weight after surgery becomes effortless.

Close post-operative monitoring is important to ensure the best results. Usually, you’ll be invited back for consultations after 1, 2, 3 and 6 months, so we can keep a close eye on your progression.  Each time, we discuss the next step to ‘your new me’. And each time, you’ll have the opportunity to ask questions. During the consultation before the procedure, we’ll discuss what the operation entails and what you can expect.

At Wellness Kliniek, we aim to make people feel good about themselves. That’s why we think it is important to keep aesthetic surgery as affordable as possible. Our effective methods mean we can reduce the costs for a gastric sleeve to a minimum. Besides, the short operating time ensures a faster recovery.

What is a gastric sleeve?

A gastric sleeve operation (sleeve gastrectomy) is an operation in which the stomach is reduced. About 70 to 80% of the stomach is removed from the body, leaving a tubular (sleeve-shaped) stomach. The stomach valve (pylorus) is preserved.

The gastric sleeve operation ensures that the stomach can take in less food and that your feeling of hunger decreases. After a gastric sleeve operation, most people experience a drop in production of the so-called appetite hormone. This way, people with large appetites can lose weight more easily and aim for a healthier body weight.

Most common weight loss procedure

When people want to have a weight loss operation, they soon discover that there are many possibilities. Not everyone is familiar with the gastric sleeve operation, although this is in fact one of the most common procedures. That’s because this method is the safest option and at same time is least invasive for the body. And yet the gastric sleeve is extremely effective. You can expect to lose more than half your excess weight!

Stomach reduction: gastric sleeve Belgium

When you opt for Wellness Kliniek, you will be treated in our high-quality clinic in Genk, Belgium. Patients travel here from Belgium, Germany, France, the United Kingdom and many other parts of the world to obtain the best possible care and the safest surgical methods. After you’ve had your gastric sleeve procedure, you’ll need to stay overnight in the clinic. After the operation, you will be invited back a few times, allowing us to offer you the highest quality aftercare tailored to your body and condition.

Gastric sleeve before and after

If you’re considerably overweight, you’ll shed that excess weight with a gastric sleeve. We cannot emphasise this enough! All those diets that have been making you miserable for years will be a thing of the past. Of course you’ll eat a lot less after having had the gastric sleeve procedure, because your stomach is a lot smaller. That’s no problem though, because you’ll be a lot less hungry at the same time!

Fortunately, all bodily functions continue to work properly, because we don’t make any changes to the connections within your body.

Gastric sleeve or gastric bypass?

Want to know the difference between a gastric bypass and a gastric sleeve? A gastric sleeve involves a reduction of the stomach, but the small intestine and gastric valve are kept intact. This results in relatively fewer complications in the long run.

In some cases, however, a gastric bypass will be a better choice, for example in patients with high cholesterol and diabetes or patients that suffer from acid indigestion or acid reflux. This is because it changes the way your body digests food.

When opting for a gastric sleeve operation, you won’t suffer from the dumping syndrome, whereas this can occur when having a gastric bypass. The dumping syndrome means that the stomach empties too quickly, which can cause cramps and diarrhoea in the gastrointestinal tract (often just after eating). Although not dangerous, it is very annoying.

A gastric sleeve operation will often be preferred over a gastric bypass, because this procedure is less invasive for the body. However, if a gastric bypass suits you better, our surgeons will always tell you and be upfront with you.
