OMEGA LOOP IN CASE OF OBESITYObesity surgery in Vienna

The obesity epidemic is growing in the western countries. Many children and adolescents are now suffering from clear obesity. Inadequate diet behavior and lack of activity are generally the main reasons. Obesity is associated with metabolic disorders, immflamation, onset of insulin resistance and diabetes, increased risk for cardiovascular diseases such as heart failure and hypertension etc. Obesity has thus a negative effects on life expectancy.

Luckily, there are many treatments today. If conventional efforts to lose weight (e.g. diet or activity) are not successful, surgical treatments may be an adequate solution.

The Omega-Loop gastric bypass (Mini-Bypass) is a simplified version of the Roux-Y gastric bypass (RYGB) with only one anastomosis (connection) between stomach and small intestine. This surgical method reduces the original stomach, similar to a sleeve gastrectomy. The reduced stomach (stomach pouch) is then interconnected to the small intestine such that the food bypasses the duodenum and the first 200 cm of small intestine.

Questions and answers on the Omega-Loop gastric bypass

What is an Omega-Loop gastric bypass?

The Omega-Loop is a gastric bypass surgery separating a major part of the stomach and the small intestine from your digestive tract. The smaller stomach portion is connected directly with the small intestine. The duodenum and the first section of the small intestine are thereby bypassed, so that the digestive juices mix later with ingested food (chime), thus reducing intake of nutrients.

Do I have to take care of my diet afterwards?

It is generally advisable to keep to a sensible diet. Since the bypassed segment would have been in charge of uptake of vitamins, minerals and trace elements, these nutrients will have to be supplemented to your diet. After the gastric bypass surgery, there may be a higher sensitivity to alcohol since it arrives to the liver quicker. Therefore, regular drinking of alcohol is not advised.

Which weight loss can be expected?

Experience shows that, over the first two years after surgery, it is possible to lose 50% - 70% of the excess weight.

How long does the surgery take?

Duration of surgery is approx. 90 minutes.

When is an Omega Loop-gastric bypass recommended?

If conservative methods of weight reduction have been unsuccessful, this surgery is an effective alternative.

Is the treatment reversible?
Even though it is rarely desired or required, the steps may be reversed.
What risks are there?
Every surgery entails certain risks, which also depend on the physical and medical condition of the patient. During surgery, rare cases of cardio-vascular episodes may occur. After surgery, some patients may suffer from the so-called dumping syndrome (e.g. nausea, tachycardia, sweats, circulatory problems). In this case, reducing sugar usually solves the problem.
When can I take up sports again?
You may reassume sport activity after approx. 4 weeks.
