If you are considering having the gastric bypass procedure done, it is important that you understand the risks involved. At the time a decision is made to have the surgery, you will be asked to sign a consent form stating you understand all the risks involved. You are encouraged to ask any questions at the time of your consultation. Some of the risks are as follows:

Bleeding
Infections
Death
Follow-up surgeries to correct complications, or to remove excess skin
Gallstones due to significant weight loss in a short amount of time
Gastritis (inflammation of the lining of the stomach)
Vomiting from eating more than the stomach pouch can hold
Iron or vitamin B12 deficiencies (if they occur) can lead to anemia
Calcium deficiency (if it occurs) can contribute to the development of early osteoporosis or other bone disorders

Risks of Gastric Banding:

Risks common to all surgeries for weight loss include an infection in the incision, a leak from the stomach into the abdominal cavity (resulting in an infection called peritonitis), and a blood clot in the lung (pulmonary embolism). About one-third of all people having surgery for obesity develop gallstones or a nutritional deficiency condition such as anemia or osteoporosis.
Perforation or tearing in the stomach wall may require an additional operation.

Access port leakage or twisting may require an additional operation.
In extreme cases an outcome can result in death
May not provide the necessary feeling of satisfaction that one has had enough to eat.
The band portion of the lap band slips and the small gastric pouch above the band becomes larger. This can cause a partial obstruction and vomiting and may require removal of the band. This problem is prone to occur early after the lap band has been placed and is more likely to occur if there is repeated vomiting. Generally a liquid diet is recommended for the first month after the lap band operation.
Slower initial weight loss than Gastric Bypass or BPD.
Regular follow-up critical for optimal results.
Requires an implanted medical device (the lap band).
In some cases, the lap band's access port may leak and require minor revisional surgery.

Risks of Gastric Sleeve:

Sleeve gastrectomy is more common in Europe, but most American health insurance carriers still consider it an investigational procedure and do not cover the cost.
In extreme cases the outcome can result in death
Anytime you have anesthesia or surgery, there is a risk of blood clots, other complications or death.
Do not smoke. Smoking would put you at high risk for infection, blood clots, slow healing and other life-threatening complications.
Complications can occur with the stapling, such as leaks or bleeding.
You may need malabsorptive surgery – intestinal bypass or duodenal switch – in addition to your sleeve gastrectomy in order to lose all the weight you need and want to lose.
The smaller portion of the stomach may stretch.
Foods that you eat now may cause discomfort, nausea or vomiting after your surgery.
Gastric surgery puts you at higher than normal risk of developing gallstones and gallbladder disease.
You will not lose weight or maintain your weight loss unless you eat a healthy diet and exercise regularly. This is the reason we stress long-term follow-up with our center and your doctor.
