This procedure is the most often implemented surgical procedure to treat obesity. First, the gastric volume is reduced, thus, diminishing the amount of food the patient can eat is reduced. Then the absorption of nutrients is diminished since the distance taken in the smaller intestines is reduced.
This operation is especially preferred on patients who have the habit of high-calories diet, for patients in this group eat few but high calories food. Reaching sufficient weight loss through surgical options limiting food intake only may not be possible. Gastric bypass ensures that nutrient absorption is affected and eliminated from the body without being used, besides reducing the gastric volume.
After this operation, patients lose 70-80% of their excess weight within 1-2 years. This result is close to perfect. On the other hand, the adaptation period to the new dietary habits is easier.
The most important drawback of this operation is that certain vitamin deficiencies may occur as a result of the malabsorption of food nutrients. However, this problem can be eliminated by external vitamin support. Experienced surgeons inform their patients and take the necessary measures.
