GASTRIC BYPASS SURGERY
Gastric bypass surgery is a treatment for serious obesity, BMI greater than 40, that changes how the patient’s small intestine and stomach handle food. The stomach will be smaller therefore the patient feels full with less food. The surgery has minimal side effects and is reliable with acceptable risks. In the first year after surgery, most patients lose 4.5 to 9 kilograms within a month. Patients can lose one half or more of the extra weight in the first 2 years by following the exercise and eating guidelines that the doctor and dietician have set.
Long considered the “Gold Standard” of weight loss operations, a Gastric Bypass procedure creates a small stomach pouch that is reconnected to the small intestine.
The stomach is reduced from about the size of a football to the size of a lemon, or 30-cc. The remainder of the stomach is “bypassed” along with the first port of the small intestine. This results in reduced volume of food that can be ingested and limits intestinal absorption. Because of this, it’s considered a restrictive and malabsorptive operation, and supplemental calcium, iron and vitamin B12 are needed.
Most Surgeons prefer the minimally invasive laparoscopic approach for bypass surgery, which typically result in smaller scars and less pain than open surgical procedures. In laparoscopic procedures, it’s common patients can leave the hospital after a few days and return to work within one month.
Gastric bypass surgery has 2 segments to the procedure.
First, a small pouch is created by dividing the top part of the stomach that is approximately 30 milliliters in volume.
Next, the small intestine is divided and the bottom part is connected to the new small pouch.
The surgery is then completed by connecting the top part of the separated intestine to the small intestine allowing nutrients and calories to bypass part to the intestine resulting in less fat absorption therefore patients lose weight.
Most patients stay in the hospital 1-4 days after surgery and will be able to return home when the patient can eat liquefied food without vomiting and able to move around without pain medication given through an IV.
Follow-up care and support is offered 2 weeks after surgery and check-up exams will be scheduled once every 4 months for the first year.
After the first year, an appointment is made once a year to monitor the patients progress and health.
