Bariatric (weight loss) Surgery

Bariatric surgery is the general term for a variety of weight loss surgical procedures. These procedures are tools, not cures, to help treat weight-related health problems. In other words, weight loss surgery is intended not only to decrease your weight but also to improve your overall health. To do this, the transformative journey requires work and commitment. A comprehensive program, such as the ones we provide, should include nutritional counseling, support and a follow-up plan to best accomplish weight loss after surgery. We’re here to help.

Results can be lifesaving

Obesity is a major health issue that contributes to the development of many life-threatening or disabling health conditions. Following bariatric surgery, patients are typically able to lower dosages or even discontinue medications associated with elevated blood sugar and/or high blood pressure. Among the other benefits are improved incidences of acid reflux and lowering cholesterol. Ultimately, the heart and lungs are working less hard and that means an improvement in quality of life.

Weight loss procedures can reduce the risk of obesity-related conditions, such as:

  • Asthma
  • Arthritis
  • Certain cancers, such as endometrial, breast, prostate and colon cancers
  • Diabetes
  • Dyslipidemia (abnormal concentrations of lipids in the blood)
  • Gallbladder disease
  • Gastrointestinal reflux disease (GERD)
  • Heart disease
  • Hypertension
  • Osteoarthritis
  • Respiratory problems
  • Sleep Apnea

Weight loss procedures:

Gastric bypass

The Roux en-Y gastric bypass – also referred to as simply “gastric bypass” – is the most common and successful type of malabsorptive surgery. With a malabsorptive procedure, there is a restriction in food intake and the amount of calories and nutrients the body absorbs.

During gastric bypass, a smaller stomach pouch is created and the small intestine is attached to the pouch to allow food to bypass the lower stomach and part of the small intestine. It is both non-reversible and non-adjustable. Long-term success depends on adhering to new rules for eating.

Advantages of gastric bypass include:

  • Average weight loss is generally higher than with gastric banding or sleeve surgeries
  • Weight loss is generally maintained the longest in comparison to other weight loss procedures

Gastric sleeve

The vertical sleeve gastrectomy, also referred to as the “gastric sleeve,” is a form of restrictive weight loss surgery in which approximately 85 percent of the stomach is removed. The remaining stomach is about the size of a banana.

Advantages of gastric sleeve include:

  • No postoperative adjustments are required
  • Patients may lose an average of 55 percent of their excess weight
  • It may help resolve high blood pressure and obstructive sleep apnea
  • It may help improve Type 2 diabetes and hyperlipidemia

Find out if you’re a candidate for weight-loss surgery

Patients may qualify for surgery if they have a BMI of at least 40, or if they have a BMI of at least 25 and also have other significant issues related to weight, such as high blood pressure or diabetes.

See if you qualify for weight loss surgery by checking your BMI and taking our free bariatric surgery candidate assessment.
