Bariatric Surgery

A bariatric surgery procedure is a type of weight loss surgery that restricts the amount of food the stomach can hold. Weight loss surgery today is done using what is referenced to as ‘minimally invasive’ techniques or laparoscopic surgery.

Common procedures

Exactly what is Bariatric Surgery? The most common of all the bariatric surgery processes are:

  • Sleeve gastrectomy;
  • Adjustable gastric band;
  • Gastric bypass;


Each of these surgeries has its own advantages as well as disadvantages.


Qualifications include BMI of 40 or more than 100 lbs overweight, or BMI 35 and at least two co-morbidities obesity-related problems such as:

  • Hypertension;
  • Type II diabetes;
  • Sleep apnea;
  • Fatty liver disease non-alcoholic;
  • Lipid abnormalities;
  • Osteoarthritis;
  • Gastrointestinal disorders;

The NIH as well as the American College of Surgeons (ACS) and the American Society for Metabolic and Bariatric Surgery (ASMBS) also recommends that this surgery be performed by a physician who is board certified and have a specialized training in metabolic and bariatric surgery, and at a center where there is anexpert team for all follow-up care.

Expert team

This team of experts include a:

  • Exercise physiologist or specialist;
  • Nutritionist;
  • Mental health professional.


Additionally, many insurance companies require that this type of surgery be done at a facility that meets ASMBS approved quality standards.

Successful surgeries

Close to 50% of patients might regain a very small amount of weight – 5%, 2 years or more following their surgery. But, longitudinal studies find that many patients having this surgery maintain a success with weight-loss long-term. Weight-loss is considered to be “successful” when the loss of weight is equal to or greater than 50% of surplus body weight.

Patient determination

But in most cases the results of success is determinated by the patient and by their professed amount of improvement in their quality of life. Also successful results can go over or under the subjective definition. This massive and well sustained reduction of weight with bariatric surgery is in contrast to the experience that many patients have had formerly with therapies that are non-surgical.
