Put an end to morbid obesity with the Gastric ByPass

Among the treatments against obesity, the Gastric ByPass is one of the most complete surgical procedures for stomach reduction with surgery.

This mixed method allows patients to lose up to 75% of their excess weight. Limiting the amount of food ingested and nutrients absorbed on a daily basis. This stomach reduction will put an end to the diseases associated with extreme obesity and will restore, over time, the state of health.

Together with the Gastric Sleeve, the Gastric ByPass leads the ranking of bariatric surgeries performed both in our country and abroad.

How is the Gastric ByPass bariatric surgery performed?

Gastric ByPass stomach reduction is performed laparoscopically. A minimally invasive alternative that will reduce recovery times, as well as possible discomfort and pain during the weight loss process.

The objective of this procedure is to reduce the capacity of the stomach as much as possible and to have the food intake go directly from this new stomach to the end of the intestine. The patient will feel more satiety with less food consumption.

This bariatric surgery is considered a malabsorptive technique:
– Reduction of the capacity and size of the stomach.
– Elimination of the absorption of a large part of nutrients.

Gastric ByPass is performed under general anesthesia and requires hospitalization for 2 to 4 nights. The approximate intervention time is about 3 hours. The results are visible from the first moment and are progressive over time.

During the entire weight loss process, the nutrition team of Doctor Life Clinics will accompany the patient in his or her recovery. Indicating guidelines and recommendations to be followed in order to modify their lifestyle habits.

Gastric ByPass is usually the most recommended option after failed attempts of significant weight loss with other minimally invasive methods such as the Gastric Balloon.

Thanks to this bariatric intervention, the patient will be able to put an end to associated diseases such as type II diabetes, arterial hypertension, fatty liver, heart disease, asthma and cardiac alterations, among others.
