The Weight Loss (Bariatric) Program at Orlando Regional Medical Center

It's always best to lose weight through a healthy diet and regular physical activity. But if you're among those who have tried and can't lose the excess weight that's causing your health problems, minimally invasive weight loss surgery may be an option.

At Orlando Regional Medical Center (ORMC) our dedicated multidisciplinary team of specially trained individuals are available to assist you with all aspects of weight loss surgery. Led by highly skilled, board certified surgeons with extensive training in performing laparoscopic bariatric procedures, our team includes an experience nurse directing the program, a registered dietitian to provide long-term weight management and two patient/family counselors, starting at the time of consultation and lasting for life.

Bariatric Surgery: Is this weight loss surgery for you?

Generally bariatric surgery is for people who are unable to achieve or maintain a healthy weight through diet and exercise, are more than 100 pounds overweight, and who have health problems as a result. You may want to consider surgery if:

  • Your body mass index (BMI) is above 35*
  • You have two serious health problems such as diabetes, high blood pressure, sleep apnea, or osteoarthritis.

*ORMC sees patients with a BMI up to 65.

How do you prepare for Bariatric Surgery?

Candidates for bariatric surgery go through an extensive screening process. Your willingness and ability to follow through with recommendations made by your health care team help determine your readiness. Also, the team identifies which aspects of your health are expected to improve as well as any aspects of your health which may present risks. Only after all these factors are considered will you be considered for approval.

What to expect after Bariatric Surgery

The estimated weight loss with sleeve gastrectomy is approximately 65% of one's excess weight. With Bariatric Surgery estimated weight loss is approximately 40-50% of one’s excess weight, which may be achieved over two years.

Keep in mind that weight loss surgery is not a quick fix. To be successful, your surgery must be followed by lifestyle changes in eating and behavior.

Roux-en-Y Gastric Bypass

Roux-en-Y Gastric Bypass Surgery is the most common and successful combined procedure in the United States. It is considered the ‘gold standard’ of bariatric surgery.

First, we create a small stomach pouch to restrict food intake. Next, a Y-shaped section of the small intestine is attached to the pouch to allow food to bypass the lower stomach, the duodenum (the first segment of the small intestine), and the first portion of the jejunum (the second segment of the small intestine). This reduces the amount of calories and nutrients the body absorbs.

Most patients lose weight quickly and continue to lose for 18 to 24 months after the procedure. With the Roux-en-Y gastric bypass, many patients maintain a weight loss of 75 to 85 percent of their excess weight for 10 years or more. Because combined operations result in greater weight loss than restrictive operations, they may also be more effective in improving the health problems associated with severe obesity, such as hypertension (high blood pressure), sleep apnea, type 2 diabetes, and osteoarthritis. Combined procedures are more difficult to perform than the restrictive procedures. They are also more likely to result in long-term nutritional deficiencies. This is because the operation causes food to bypass the duodenum and jejunum, where most iron and calcium are absorbed. That is the reason why long time replacement as well as follow up with your surgeon is essential.

Laparoscopic Sleeve Gastrectomy

With the potential for greater weight loss and less complication than gastric bypass sleeve gastrectomy is now offered at ORMC. Sleeve Gastrectomy is the most recent addition to bariatric surgery. Laparoscopic Sleeve Gastrectomy generates weight loss by restricting the amount of food that can be eaten by removing 85% of the stomach without bypassing the intestines or causing gastrointestinal malabsorption, a common complication with traditional gastric bypass. The stomach is restricted by dividing it vertically and removing a large portion of the stomach. The stomach that remains is shaped like a long narrow tube that measures between two and five ounces.This procedure greatly reduces Ghrelin-hormone production which helps reduce appetite and the hunger sensation. Results based on a five-year and three-year case study suggest the Vertical Gastrectomy, also known as Sleeve Gastrectomy, has weight loss similar to other procedures with lower risk of complication. 


  • Minimally invasive procedure
  • Shorter hospital stays – Most patients stay overnight and are discharged the next day
  • No implantable devices are used
  • Potential greater weight loss
  • There is no need for adjustments – no needles
  • No risk of internal hernia
  • No risk of marginal ulcers 


  • Minimally invasive procedure
  • No cutting or stapling of the stomach or bypassing the intestines
  • Shorter hospital stays – most patients stay overnight and are discharged the next day
  • Reduced pain
  • Removable band – If for any reason the band needs to be removed, the stomach generally returns to its original form

All medical professionals involved in the surgical treatment of clinical obesity agree on at least one thing about successful bariatric surgery: weight loss is easier and faster when patients can access personal help through local support groups. Post-operative patients are strongly encouraged to attend. We welcome pre-operative patients that are interested in learning more about the lifestyle changes necessary to be successful with weight loss to stop by as well.
