What is RNY Gastric Bypass Surgery:
Gastric bypass, also called Roux-en-Y (roo-en-wy) gastric bypass, is a type of weight-loss surgery that involves creating a small pouch from the stomach and connecting the newly created pouch directly to the small intestine. After gastric bypass, swallowed food will go into this small pouch of stomach and then directly into the small intestine, thereby bypassing most of your stomach and the first section of your small intestine.
Gastric bypass is one of the most common types of bariatric surgery in the United States. Gastric bypass is done when diet and exercise haven’t worked or when you have serious health problems because of your weight.
When is it done:
Gastric bypass is done to help you lose excess weight and reduce your risk of potentially life-threatening weight-related health problems, including:
- Gastroesophageal reflux disease
- Heart disease
- High blood pressure
- High cholesterol
- Obstructive sleep apnea
- Type 2 diabetes
Gastric bypass is typically done only after you’ve tried to lose weight by improving your diet and exercise habits.
In general, gastric bypass and other weight-loss surgeries could be an option for you if:
- Your body mass index (BMI) is 40 or higher (extreme obesity).
- Your BMI is 35 to 39.9 (obesity), and you have a serious weight-related health problem, such as type 2 diabetes, high blood pressure or severe sleep apnea. In some cases, you may qualify for certain types of weight-loss surgery if your BMI is 30 to 34 and you have serious weight-related health problems.
But gastric bypass isn’t for everyone who is severely overweight. You may need to meet certain medical guidelines to qualify for weight-loss surgery. You likely will have an extensive screening process to see if you qualify.
You must also be willing to make permanent changes to lead a healthier lifestyle. You may be required to participate in long-term follow-up plans that include monitoring your nutrition, your lifestyle and behavior, and your medical conditions.
