The gastric bypass has long been one of the most frequently performed gastric reduction methods, especially in the USA.
Gastric bypass surgery is particularly suitable for patients with a BMI of over 35 . This method has generally promised effective success, but it is increasingly being overtaken and displaced by gastric sleeve surgery.
The gastric bypass surgery is performed minimally invasively . The stomach is closed and severed with staples just below the esophagus. A connection between the small intestine and the remaining part of the stomach ensures that food is transported to the small intestine.
The stomach is thus bypassed and is in the “bypass”. The gastric bypass usually significantly reduces the amount of food, which means that the patient can lose a lot of weight immediately after the procedure. However, this method has the stomach reduction, compared with the sleeve gastrectomy surgery , some drawbacks. This includes, for example, the lifelong intake of dietary supplements and vitamins and minerals.
Weight loss is fairly rapid within the first year after gastric bypass surgery. The target weight is usually reached after 18 months.
With this operation you lose an average of 50% of your excess body weight.
For example, a patient 1.70 tall and 140 pounds will lose about 50-60 kilograms after surgery and drop to about 80-90 kilograms.

- Due to the rapid weight loss, there is a risk of gallstones
- When ingesting carbohydrates or after consuming large amounts of food, symptoms such as nausea, vomiting, diarrhea, sweating, fatigue, and weakness may occur
