Understanding Gastric Bypass Surgery

Laparoscopic Roux-en-Y Gastric Bypass, also known as Gastric Bypass or RN, is a weight loss surgery in which the majority of the stomach is bypassed and a small pouch is created. The RNY is the most common laparoscopic weight loss surgery performed in the U.S. The technique is less invasive than traditional open surgery and typically involves a quicker recovery time.

WellStar Medical Group bariatric surgeons helped pioneer laparoscopic weight-loss procedures and perform hundreds of these procedures each year.

RNY achieves weight loss in all weight ranges with a solid long-term record of safety. Weight loss on average is in the range of 70-75% of excess body weight. With continued program follow-up, the loss is fairly well sustained over time.

Bariatric surgery is an option for morbidly obese individuals who have not been successful with other weight loss methods. Your WellStar physician will discuss the options to determine if the RNY is a good choice for you. Considerations include your body mass index and related medical conditions such as diabetes, high blood pressure, sleep apnea and/or disabling osteoarthritis.

A number of complications are possible. Vitamin deficiencies are usually corrected with supplements. Another surgical complication is dumping, which can occur when rich, sugary foods move quickly through the stomach into the small intestine. Symptoms can include nausea, diarrhea, sweating and fainting. Your physician will discuss these and other possible issues to make sure that you fully understand the procedure and possible complications.
