LAP-BAND vs Gastric Bypass

DayOne Health specializes in adjustable gastric banding — one if the safest weight-loss procedures currently available. Success rates with gastric banding are comparable to those of gastric bypass — without the risks of an invasive surgical procedure.


Currently, gastric bypass surgery is the most commonly performed type of weight-loss surgery. About 150,000 gastric bypass surgeries are performed each year in the United States. Gastric bypass is both a “restrictive” and a “malabsorptive” procedure, meaning that it not only reduces the size of the stomach, but also inhibits the body’s ability to absorb calories.

Normally when you eat, food passes through the stomach to the small intestine — where most nutrients are absorbed — and then into the large intestine. During gastric bypass surgery, the surgeon removes part of the patient’s stomach and connects the part that is left to the middle part of the small intestine. Not only does the smaller stomach allow the patient to feel full sooner, but food “bypasses” part of the small intestine, resulting in the absorption of fewer calories.

Because gastric bypass requires cutting and stapling of the digestive tract, the surgery cannot be performed on an outpatient basis. In order to undergo the surgery, patients need to be admitted to the hospital and stay there up to three days after surgery. Complete recovery may take up to three months.


Studies increasingly show that despite the popularity of gastric bypass, complications and risks resulting from this surgery are even more serious — and occurring at higher rates — than initially thought. With mortality rates as high as 2% for gastric bypass procedures, prospective patients must consider their treatment options carefully. Furthermore, the long-term consequences of cutting the stomach and permanently altering the digestive tract are still not fully understood.

The adjustable gastric band is safer, far less invasive, and just as effective as gastric bypass in fighting excess weight. The potential risks and complications associated with the procedure are minor in comparison to any other form of bariatric surgery. With the LAP-BAND, there is no cutting or stapling of the digestive tract. As a result, the procedure takes much less time and can be performed on an outpatient basis. This means that after LAP-BAND surgery, you’ll recover in the comfort of your own home instead of the hospital. In addition, post-surgical recovery time for LAP-BAND patients is faster than for those undergoing gastric bypass — about six weeks compared to three months.

The risks to your health, and your life, are significantly lower with the LAP-BAND than with gastric bypass. Since the LAP-BAND is a purely restrictive procedure (reducing the size of the stomach without altering the digestive tract), you will avoid the vitamin and mineral deficiencies and “dumping syndrome” associated with most other forms of bariatric surgery, including gastric bypass.Your natural digestive processes remain fundamentally unchanged. Compared to gastric bypass, dietary requirements with gastric banding are not as restrictive, because the body’s ability to absorb nutrients is not affected; however, you do still need to ensure that you are eating a balanced diet not too rich in calories and abundant in nutrients.



  • ✔ The LAP-BAND can be removed, with the stomach usually returning to its normal shape.
  • ✔ Slower initial rate of weight loss. After three to five years, weight loss is comparable to gastric bypass.
  • ✔ Low risk of nutrient deficiencies.
  • ✔ No risk of dumping syndrome.
  • ✔ Mortality rate: 0.05%1
  • ✔ Total complications: 9%2
  • ✔ Major complications: 0.2%2
  • ✔ No cutting or stapling of the stomach. No removal of any part of the stomach or intestinal rerouting.
  • ✔ Can be adjusted without additional surgery during an office visit. Adjustments can customize rate of weight loss.

Gastric Bypass Surgery


  • ✔ Cannot be reversed.
  • ✔ Rapid weight loss. Weight can be regained over time.
  • ✔ Increased risk for anemia, osteoporosis, and other medical conditions.
  • ✔ Risk of dumping syndrome. Symptoms include cramps, nausea and a rapid heartbeat.
  • ✔ Mortality rate: .5% (ten times higher)1
  • ✔ Total complications: 23%2
  • ✔ Major complications: 2%2
  • ✔ Involves cutting and stapling of the stomach, removal of a portion of the stomach, and rerouting of the intestine.
  • ✔ Not adjustable. Any adjustments to improve weight loss require additional surgery.


One of the major advantages of the LAP-BAND is that it is fully adjustable and reversible. While it is intended to be a long-term or permanent solution, if any complications become serious or life-threatening, the band can be completely removed or replaced. Your band can also be fully deflated for any reason — such as during an illness or pregnancy — when your body may require more food. In other words, without any additional surgery, you can return your stomach to its pre-surgical shape at any point in time. For patients who experience severe problems with gastric bypass, reversal is not impossible, but is difficult and carries high risks and a long recovery.


As with any medical procedure, there are some potential risks associated with the LAP-BAND. Though infrequent, LAP-BAND risks include problems with band placement, movement of the band, and infection or leakage of the band or port. In addition, some patients experience more post-operative gastric symptoms — such as nausea and vomiting — than others. It is also possible that you may not lose weight, that you may even gain weight, or that very rapid weight loss could cause health problems. But even these potential complications occur at dramatically lower rates than with gastric bypass. Following the recommendations of your doctor and nutritionist will help reduce your risk of these types of complications.

Important LAP-BAND® System Safety Information

Indications: The LAP-BAND® System is indicated for weight reduction for patients with obesity, with a Body Mass Index (BMI) of at least 40 kg/m2 or a BMI of at least 30 kg/m2with one or more obesity-related co-morbid conditions. It is indicated for use only in adult patients who have failed more conservative weight reduction alternatives, such as supervised diet, exercise and behavior modification programs. Patients who elect to have this surgery must make the commitment to accept significant changes in their eating habits for the rest of their lives.

Contraindications: The LAP-BAND® System is not recommended for non-adult patients, patients with conditions that may make them poor surgical candidates or increase the risk of poor results (e.g., inflammatory or cardiopulmonary diseases, GI conditions, symptoms or family history of autoimmune disease, cirrhosis), who are unwilling or unable to comply with the required dietary restrictions, who have alcohol or drug addictions, or who currently are or may be pregnant.

Warnings: The LAP-BAND® System is a long-term implant. Explant and replacement surgery may be required. Patients who become pregnant or severely ill, or who require more extensive nutrition may require deflation of their bands. Anti-inflammatory agents, such as aspirin, should be used with caution and may contribute to an increased risk of band erosion.

Adverse Events: Placement of the LAP-BAND® System is major surgery and, as with any surgery, death can occur. Possible complications include the risks associated with the medications and methods used during surgery, the risks associated with any surgical procedure, and the patient’s ability to tolerate a foreign object implanted in the body. Band slippage, erosion and deflation, reflux, obstruction of the stomach, dilation of the esophagus, infection, or nausea and vomiting may occur. Reoperation may be required. Rapid weight loss may result in complications that may require additional surgery. Deflation of the band may alleviate excessively rapid weight loss or esophageal dilation.
