What Is RNY Gastric Bypass Surgery?
Roux-en-Y gastric bypass (RYGB) surgery is a restrictive and malabsorptive procedure. This means that the surgeon creates a small pouch of the stomach, so you don’t need to eat as much to feel full. The surgeon also bypasses part of your small intestine, so less food is digested and absorbed into the body. The result is weight loss, without malnutrition or malnourishment.
RNY Gastric Bypass Advantages
RYGB surgery has been shown to help people who are obese lose weight and improve related health problems. It helps people with type 2 diabetes get off insulin. Also, improved quality of life including energy level and outlook — contributes to the effectiveness of the surgery.
RNY Gastric Bypass Disadvantages
The RNY gastric bypass procedure has a higher death rate than other weight-loss surgeries. Major complications include bowel obstruction, hernia, or staple line leak. The surgeon needs to cut through stomach tissue when creating the small pouch for the RNY gastric bypass, and this can lead to stomach perforation (or hole)
Complication rates with the RNY gastric bypass surgery may be higher than those of other types of weight loss surgery. There is a chance you could develop one or more of these serious complications:
– vitamin deficiencies, especially vitamin B12 deficiency
– postoperative bleeding
– liver disease or failure
– heart disease
– gallstones and gallbladder disease
People who have a normal BMI can be at increased risk of complications from a gastric bypass. In addition, people with an eating disorder may not be good candidates for the RNY procedure.
RYGB surgery is a more complex operation. It involves changing the digestive system so it will lose weight. There are two key parts to this process:
– creating a small pouch of the stomach from part of the larger gastric pouch, which reduces the amount you can eat before feeling full
– bypassing most of the small intestine so that your body absorbs fewer calories from food
The perioperative mortality rate after RNY Gastric Bypass Surgery is high, and its cardiovascular effects have been poorly studied. The long-term efficacy of the procedure is unknown with a majority of patients experiencing weight gain after 10 years. Increased rates of reoperation for recurrent or new diseases are also a major factor in the long-term mortality associated with RNY Gastric Bypass.
