Sheila K. Partridge, MD, FACS, FASMBS, serves as the medical director for the Center for Weight Loss Surgery (CWLS) at Newton-Wellesley Hospital and specializes in general and bariatric surgery. Since joining Mass General Brigham in 2002, she has focused on minimally invasive and robotic weight loss (bariatric) surgery, helping patients lower and manage their weight and control serious health conditions caused by obesity.

Susana Wishnia, MD, FACS, FASMBS, has been a minimally invasive and bariatric surgeon in the CWLS for over 10 years. Together Dr. Partridge, Dr. Wishnia, and the CWLS team of nurses, dietitians, psychologists, physicians, and staff have helped thousands of patients achieve improved health and well-being.

"Weight loss surgery has advanced from traditional open surgeries with large incisions to minimally invasive surgeries performed through small incisions," Dr. Partridge said. “Robot-assisted weight loss surgery is now the most commonly used technique and today makes bariatric surgery safer than even routine gallbladder surgery."

Drs. Partridge and Wishnia answer frequently asked questions about weight loss surgery, including what to expect and why Newton-Wellesley Hospital is a leader in the field in Greater Boston.

What are the benefits of minimally invasive bariatric surgery?

In general, bariatric surgery is a safe procedure and is quite effective when combined with lifestyle changes and long-term follow-up. The minimally invasive technique of robotically assisted bariatric surgery takes weight loss surgery to the next level. Robotic bariatric surgery uses computers and video technology to make it even safer, less invasive, and less painful than traditional surgeries.

Recovery times are faster as well. Since the procedure is less invasive, patients often heal more quickly and return to their daily lives sooner.

In the long term, robotic weight loss surgery is highly effective in promoting weight loss and treating related medical conditions like diabetes, sleep apnea, and high blood pressure.

Is robotic/laparoscopic weight loss surgery right for me?

Surgery is a great option for many patients, particularly those with severe obesity. This includes individuals with a body mass index (BMI) of:

• 40 or more, or
• Over 35 with other medical conditions such as diabetes, sleep apnea, and high blood pressure

To qualify for insurance coverage, you must also meet your insurer's requirements. These often include documented attempts at other weight loss methods and pre-surgical evaluations.

Robotically assisted laparoscopic bariatric surgery/weight loss surgery may not be suitable for every patient. During our consultation, we'll discuss all viable options and together decide the best course of action for you.

Are there any risks to weight loss surgery?

Like any surgical procedure, weight loss surgery does carry some risks, both during the operation and throughout the initial recovery phase, which typically spans the first six weeks after surgery.

During the first 24 hours while you're in the hospital, we'll monitor you closely for potential complications such as bleeding and infection. Over the following weeks, our team will continue to check in with you regularly to ensure your recovery is going smoothly. During this time, you'll also meet with registered dietitians to make sure you get the nutrition you need to support healthy weight loss.

Looking at long-term care, we'll help you manage potential risks associated with nutritional intake and weight loss. Regular follow-ups are part of this strategy, allowing us to monitor your health and adjust your care plan as needed. These follow-ups are key to maintaining your health and ensuring the long-term success of the surgery.

What is the recovery process like after bariatric surgery?

During the first 24 hours, you'll be able to walk and use the restroom on your own as well as sip liquids. Typically, patients spend one night in the hospital and can go home the next day if there are no complications.

You should avoid lifting anything heavier than 10 pounds for the first month. You'll also need to follow a specially designed diet during this initial recovery period to ensure you heal properly.

We often recommend that patients take off at least two weeks from work. If your job is a physical one, you might need to take off four to six weeks from work. Our team will help with any necessary paperwork for medical leave to ensure your employer can accommodate your recovery needs.

Will I need to change my diet after bariatric surgery?

Yes, dietary changes will let your stomach heal properly while still giving you needed nutrition. You should drink a lot of water and non-caloric liquids and follow a blended or pureed diet for the first month.

You'll also need to take vitamins and supplements for the rest of your life. That's because bariatric surgery changes how your body absorbs nutrients, making supplements necessary to prevent deficiencies and maintain overall health.

We'll monitor your progress through regular reviews of blood test results and may suggest changes to your supplements or diet to ensure you're getting the nutrients you need.

What results can I expect after bariatric surgery?

Weight loss can differ from patient to patient, depending on their starting weight, the type of surgery performed, their health status, and their physical activity level. On average, patients can expect to lose about 60% to 80% of their excess weight within the first year to 18 months. The most significant weight loss typically occurs in the first six months, with the initial month often showing the most rapid loss of excess weight and improvements in other medical conditions.

It's important to attend all scheduled follow-up appointments with your doctors. These visits allow us to monitor your progress closely and make any necessary adjustments to your diet, exercise, and medication routine.

At the CWLS, we have a strong track record of success, with over 95% of our patients achieving successful weight loss. This success is defined as losing at least 60% of their excess weight and maintaining that loss for the long term.

Are there certain things I can do to make my bariatric surgery a success?

Yes! Ensuring the success of your weight loss surgery largely depends on your active involvement and commitment to long-term lifestyle changes. Follow your care team's instructions, especially as they relate to your diet, physical activity, and medication. Attend all scheduled follow-up appointments so that we can actively track your progress. Participate in the support groups we offer, both online and in-person, to connect with others who are also navigating their own weight loss journey.

You're not alone in this journey. Our team will be here to support you. Should you have any concerns or questions along the way, please reach out to our staff by phone or through Patient Gateway (for non-urgent matters). Together, we'll make sure you stay on track to meet your health goals.
