Back to a healthy weight with a gastric-bypass

A gastric bypass is completely reversible

The aim of Gastric Bypass surgery is to safely reduce your excess weight to a normal, healthy level. Nutrients are absorbed normally. The operation is completely reversible.

With this type of surgery:

  • On the one hand: a stomach reduction is carried out so that you eat less, feel full more quickly and for longer,
  • On the other hand: the bypass ensures that- between the new small stomach and the first small intestinal loop- no food enters the main stomach. In the main stomach we find the cells which produce the hormone ghrelin, responsible for making you feel hungry and for making you crave sugars.

This procedure lowers the level of ghrelin in your blood, automatically reducing the sensation of feeling hungry and the craving for sugars. No organs or parts are removed. The digestive system continues to function normally, as does the second part of your stomach.

All nutrients are absorbed, as is any medication. Your stools remain normal.

Weight loss after gastric bypass surgery

In the first year following your operation you will lose between 60 – 70% of your excess weight. Weight loss is greatest during the first few months. The first six days five kg, after six weeks twelve kg. After that 3-4kg a month.

The aim of gastric bypass surgery

Less hungry = eat less

The aim of the operation is:

  • To create a bypass which means:
  • You will only be able to eat smaller quantities at mealtimes;
  • You will not feel so hungry and experience less cravings;
  • Food no longer enters the main stomach and or comes into direct contact with the stomach’s digestive juices, gall and pancreas (in the first part of the small intestine: total length 6 m.). This allows the hormones to work more efficiently: ghrelin, adiponectin and GLP 1 will play a useful role in your weight loss.

Results of the Gastric Bypass

Good digestion with a Fobi gastric bypass, but less foodintake

The Fobi gastric bypass (Fobi pouch – Fobi bypass) ensures that your body’s digestive system functions normally, but takes in less food; resulting in drastic weight loss.

The greatest advantage of this stomach operation is that it will seriously improve your health: your cholesterol levels will decrease, you will feel fitter, your sleep apnea and high blood pressure will disappear and your back complaints will improve.

Above all the procedure can cure diabetes or at least the vast majority of the complaints associated with it will disappear. The procedure ensures that you will eat healthily afterwards as the foods you will tolerate best of all are fruit and vegetables.

Gastric Bypass Surgery
The operation

Safe, efficient and commonly performed

The stomach bypass operation according to Fobi (also known as the Fobi gastric bypass or the Fobi pouch) is the most commonly performed weight loss surgery. The operation is safe and efficient. With a gastric bypass the surgeon reduces the capacity of the stomach to about the size of an egg. During the procedure the volume of this new stomach is measured, this volume also determines subsequent weight loss. A ring is also placed around this new stomach (a Fobi ring) generally with an internal diameter of 6.5cm which ensures that the new stomach doesn’t begin to expand in the long term, resulting in weight gain.

Then the surgeon takes the small intestine and connects it to the new small stomach (pouch). He also reconnects the duodenum to the small intestine so that the necessary digestive juices, 100cm further along, are added to the food.

This new connection – of the duodenum with the small intestine ensures that the stomach juices, gall and pancreatic juices can be mixed with the food. This is necessary for a normal, healthy digestion.

Gastric Bypass Surgery
Why the Fobi surgery method?

Operative technique with the least side effects

When you opt for weight loss surgery we advise you to choose the operative technique which has the least side effects and risks. The Fobi Gastric Bypass technique – the Fobi pouch is the best option.

The Fobi method is much better compared with the regular stomach bypass performed with keyhole surgery:

  • no staples that can come undone: 3-double stitches;
  • an obvious less chance of bleeding, fistulas, and leakage;
  • less risk of hernias;
  • a safer positioning of the attached small intestinal loop;
  • better measurement of the new stomach’s volume;
  • extra band around the new stomach;
  • positioning of the attached loop between the two stomach parts;
  • smaller calibrated connection between the new stomach and the small intestine;
  • the anastomosis (connection between the intestines) is performed manually.

With the regular Gastric Bypass method (via laparoscopy/ keyhole surgery) an automatic staple gun is used. The first 2,5 cm stitches are always too wide, which does not create enough restriction. Manual stitches (three double ones) are more accurate, give more reliable results and carry fewer risks.

In order to perform the stitches manually the surgeon makes an incision of about 10 cm. The scar is a little larger than with keyhole surgery (laparoscopy), but the result is safer and more reliable.

Gastric Bypass: the anaesthetic

Gastric Bypass surgery is performed under a general anaesthetic

The procedure is performed under a general anaesthetic. The anaesthetist (doctor-specialist-anaesthetist) looks after you in the operating theatre.

Am I a suitable candidate for a gastric bypass?

You have excess weight and love confectionery, pasta and sugar rich drinks?

The gastric bypass operation is particularly suitable for people who still haven’t lost their excess weight despite having tried numerous diets and who especially love confectionery, pasta and sugar rich drinks.

If your BMI is higher than 40 (women) or 45 (men), then this operation is not suitable for you, because it is technically too complicated. A gastric sleeve operation is better (operational stomach reduction) whereby you first lose between 40 and 50 kg. Only then can you switch to a gastric bypass – pouch.

Risks and side effects gastric bypass during or soon after the procedure

Risks and side effects gastric bypass during or soon after the procedure

With a gastric bypass operation you run the risk of complications caused by the operation.

The most common complications are:

  • Blood clots in the veins of the legs (thrombosis). We prescribe blood thinning drugs before and after the operation to avoid this. During the procedure you will be given special compression stockings which constantly pumps your blood around. After the procedure it is important to get out of bed and start moving around as soon as possible; our nurses will assist you with this.
  • Bleeding. The risk is very small due to our special - non laporoscopic - operating technique whereby every connection (between stomach  - intestine and small intestine) is stitched in three layers.
  • Leakage. The risk is very small because of our operating technique, whereby every connection is performed manually in three layers.
  • Chest infection. In order to avoid this we advise patients to take sufficient pain killers (e.g. paracetamol) so that you can breathe deeply with ease and dare to cough. It is best not to smoke, or at least to do so as little as possible before and after the procedure. As a preventative measure we always prescribe antibiotics to avoid infections.

Risks and side effects gastric bypass after the procedure:

Risks and side effects gastric bypass after the procedure

If you smoke too much, then you have a higher chance of a stomach ulcer. This is because the nicotine gets straight into the stomach. Other possible complications are obstruction of the intestines, the formation of gallstones and hair loss though these are extremely rare.

Another disadvantage of this operation is that the bypass can lead to the so-called ‘dumping’ syndrome. This phenomenon occurs when sugars end up too quickly in the small intestine. This results in the patient’s blood pressure falling and can result in palpitations and sweating. One advantage is that one will automatically eat less sweet and fatty foods. It does happen – but is fortunately rare – that the syndrome leads to the dumping of all food and that another solution must be found.

We do not use stapling, because there is a risk that they could come undone. Each seam is stitched manually, with three double stitches.

After drastic weight reduction your skin will not be as taut as before as it can only shrink so much. The sagging skin can be inconvenient and is not very attractive. With cosmetic surgery this problem can be solved, giving you a beautiful, slim figure.

Recovery following a Gastric Bypass

The first weeks following the surgery

Directly after the operation we advise you to eat liquid or crispy foods: soup, toast, crisprolls, crispbreads (roasted full grain bread), puddings made with semi-skimmed milk, soja milk and protein powder shakes without sugar. It is important that you eat slowly and calmly.

For six weeks following the operation you can not drink fizzy drinks such as cola, sparkling mineral water or champagne. After this period it is best to limit your consumption of these drinks.

For the first weeks following your treatment you could suffer from tiredness. Gradually you can resume your daily activities.
It is best to avoid lifting anything for the first two weeks. After this period it is very important to have a healthy exercise routine to achieve the maximum results of this procedure, and to avoid muscle wasting.

The procedure does not prevent a possible subsequent pregnancy. Sometimes men and women become more fertile when they lose weight. Though pregnancy must be avoided during the first 12-18 months after the procedure. During a possible pregnancy a healthy diet and the regular consumption of iron, folic acid, vitamin and mineral supplements are even more important.

After the operation alcohol is absorbed into the bloodstream more quickly and more efficiently. You should be aware that you will reach the legal limit for alcohol consumption faster.

Eating habits following a Gastric Bypass operation

Less hungry, quickly saturated, healthy diet

You are less hungry. During one mealtime you can eat part of a starter. You will quickly feel full.

After the procedure it is important that you are well motivated and eat a “healthy” diet. Eat vegetables, meat and fish. A healthy diet and vitamins are very important. Vitamin deficiency must be treated quickly. This is why follow up consultations are extremely important.
