Weight Loss Services

Center for Weight Loss and Bariatric Surgery

If you have struggled to lose excess weight, bariatric surgery may be the first step in a journey toward a new chapter of your life.

Bariatric surgery, also called weight loss surgery, alters the size of the stomach, small intestine or both to assist with weight loss. Numerous scientific studies have shown that bariatric surgery, combined with lifestyle modification, leads to significantly better and longer lasting weight loss when compared to lifestyle modifications alone.

UMC's Center for Weight Loss and Bariatric Surgery is supported by a multi-disciplinary team that includes bariatric surgeons, dietitians, behavioral therapists and nurse practitioners dedicated to helping our patients achieve their weight loss goals.

*Please note: Bariatric surgery is a tool designed to help you achieve your weight loss goals, BUT it cannot and will not happen without your cooperation.

For best results, patients need to actively participate in a multi-disciplinary weight loss program that includes nutritional, emotional, and exercise counseling. Patients are encouraged to utilize our peer support groups and brief psychoeducational therapies in order to both prepare for and adjust to life after bariatric surgery. Our highly trained team is committed to providing the highest level of patient care every step of the way.

Congratulations on taking the first step to a better, healthier you. We look forward to welcoming you to our Bariatric Services at UMC.

More than 1/3 of U.S. adults suffer from obesity. Obesity is a medical condition involving excess body fat that increases the risk of health problems. Obesity-related conditions include heart disease, stroke, type II diabetes and certain types of cancer.

Obesity can reduce life expectancy by up to 20 years if not treated, which is why bariatric services can be crucial to your health and survival. This weight loss solution is a way to improve your abilities to participate in everyday life and improve, if not reverse, the adverse effects of health conditions, such as:

  • Diabetes
  • Hypertension
  • Obstructive sleep apnea
  • Cardiovascular disease
  • Depression
  • Etc.

Bariatric Services are designed for those people who suffer from obesity. Obesity is measured by using Body Mass Index (BMI) calculations. To calculate your BMI, enter your height and weight into the table below.

 If you have a BMI of 35 or more, you are considered obese and may qualify for our Bariatric Services. If your BMI is over 40, you are considered morbidly obese, which is a more severe form of obesity that poses extreme risks to your health and life.

 To learn whether you are a candidate for Bariatric Surgery, please contact us at (504) 962-6262.

Our commitment is to provide you with clear, thorough information about weight loss options designed to help you make the best decision for your immediate and long-term health. Helping you successfully prepare for weight loss surgery is our top priority at UMC.

Surgical Options:

Roux-en-y Gastric Bypass (RYGB)

You can expect to lose 60-70% of your excess weight with this procedure.

  • Your new stomach will be about the size of a large thumb and the opening leaving the stomach will be about as wide as an index finger. The new pouch will be about the size of 30mL.
  • The small pouch and small outlet created by the operation and the hormonal changes will help control the feeling of excessive hunger. Changes in eating and exercise behavior will be required for weight loss and long-term weight maintenance.

Vertical Sleeve Gastrectomy

You can expect to lose 50-60% of your excess weight with this procedure.

  • During this surgery about 80% of the stomach is removed to create a small sleeve stomach similar in shape and size to a banana. The new pouch will be between 60-120 ml. It is larger than the stomach pouch created during the Roux-en-Y Gastric Bypass.
  • The small pouch and hormonal changes will help control the feeling of excessive hunger. Changes in eating and exercise behavior will be required for weight loss and long-term weight maintenance.

Note: The gastric bypass does a slightly better job than the sleeve gastrectomy at resolving medical problems.
