Comparing Gastric Bypass and Lap-Band® Procedures
Because most of the individuals who come to WeightWise are eligible to undergo both the Lap-Band and Roux-en-Y Gastric Bypass procedures, we feel it is our charge to educate them about the choices on the journey toward wellness. We do realize that in this situation, we cannot speak for the patient to determine which procedure will work best for their lifestyle. Through conversations with our surgeons and the WeightWise Medical Team, patients can learn more about the options available. In addition, people can use the information below highlighting some the benefits and risks associated with each surgery.

- Well studied procedure that is the most popular bariatric surgery within the U.S.
- More invasive and difficult procedure affecting many areas within the abdomen
- Fast weight loss with most patients averaging 65 to 80 percent of excess weight lost one to two years after surgery.
- It is a permanent, nonreversible procedure.
- Due to the fact portions of the digestive system are bypassed, poor absorption of iron, B-12 and calcium can cause a greater chance of having anemia, bone calcium loss and a small chance of metabolic bone disease. By eating foods rich in nutrients, as well as taking a multivitamin, B-12 pills and calcium supplements, patients can maintain a healthy level of minerals and vitamins and help avoid these risks.
- The bypassed portions of the abdomen cannot easily be seen using X-ray or endoscopy if there are problems such as ulcers, bleeding, or malignancy.
- Dumping syndrome can occur when a patient eats too much sugar or large amounts of food. While it is not a serious health risk, the results are very unpleasant. Symptoms include vomiting, nausea, diarrhea, weakness, sweating and faintness. Some people are unable to eat sugary foods after surgery.
- Less follow-up required
- Less strict dietary compliance required
- Weight loss averages ten years after surgery are around 55 percent of excess weight lost.
- Co-morbidities (associated medical problems) such as diabetes, hypertension, sleep apnea, joint pain and heartburn are improved or resolved in more than 90 percent of patients.

- Although it has been studied less than Roux-en-Y because it is new technology, it shows a great deal of promise for the future of weight loss surgery.
- Less invasive procedure with lower surgical risks and smaller risks of death or prolonged hospitalization.
- Slower, more steady weight loss. Patients generally settle at their final weight about two years after surgery
- Possible deficiencies due to decreased food intake. Long-term supplements recommended
- No dumping syndrome
- Long term (non-reactive) plastic material in body
- Reversible
- Adjustable (during physician office visits) to accommodate your customized weight loss needs
- No rearrangement of anatomy
- More follow-up required
- More dietary compliance required
- Long-term weight loss from 40 to 60 percent of excess weight
- Weight loss of one to two pounds per week after surgery
- Vitamin and mineral deficiencies possible which can be prevented by taking supplements.
- Other risks include infection, bleeding, blood clots, band slippage and band erosion

Individuals who have the medical conditions below are not candidates for the Lap Band procedure.
- Functional problems with the esophagus or severe gastro esophageal reflux disease (GERD).
- Surgical procedures performed on other parts of within the abdomen are permissible.
- Individuals whose residence is more than a four hour drive from their physician’s office. The Lap-Band requires close post-surgical monitoring and follow-up.
However, for some individuals, the Lap-Band may be a better option. The elderly benefit from the less invasive aspect of the procedure which provides lower surgical risks to patients who may be frail. In addition, those who are obese, but only need to loose moderate amounts of weight can benefit from this option.
