Roux-En-Y Gastric Bypass
RNY Gastric Bypass is the most frequently performed bariatric procedure in the US. It has been around for over 30 years and has stood the test of time. It is reliable and is also performed laparoscopically.
Procedures:
First 6 small incisions are made and the top part of the stomach is separated to about the size of a small egg (the pouch), then the surgeon attaches a Y-shaped section directly connected to the small intestine. Food is diverted to the small intestine bypassing the main part of the stomach where acid is formed.
This connection (the Y-shaped section) is made small, about the size of a dime. It drains the food through. This provides the restriction for portion and calories control. One can only eat ½ to one cup of food at a time.
The pouch is made of flesh and will stretch in time, allowing patients to eat more when their goal weight is met. At this time the weight loss will cease.
Eating healthy is vital to prevent weight regain.
Potential Concerns:
“Dumping syndrome” may occur when patients consume quantities of sweets or fats, like ice cream or chocolate.
Symptoms:
Dumping symptom is similar to the effects of hypoglycemia (low blood sugar). It include light headedness; cold sweats; hot flashes; palpitations; nausea; stomach cramps and diarrhea.
This reaction acts as a “deterrence” for patients who love sweets.
However not everyone who has a gastric bypass will experience this syndrome.
Gastric Bypass is more complicated than the bands or the Sleeve Gastrectomy. But is most effective way of weight loss. Gastric Bypass patient typically lost 61.6% of their excess weight.
