About HCA Florida Surgical Specialists

Weight loss surgery

We offer several types of bariatric surgery including Gastric Sleeve and Gastric Bypass (also called Roux-en-Y). Both of these surgeries are highly successful tools, along with a healthy lifestyle, used to help patients lose weight and keep it off. All weight loss surgeries work by helping your body limit calories. You should discuss all your surgical options for weight loss with your surgeon to determine which procedure is right for you.


Minimally invasive surgery

Most patients are able to have either the gastric bypass or the gastric sleeve using a laparoscopic technique. This allows Dr. Weerasinghe to work using long instruments placed in the body via incisions a few centimeters long. In some cases, the surgery will be performed “open,” with the traditional larger incision, or a surgery that begins laparoscopically may be converted to the open procedure if necessary. Minimally invasive procedures can mean less pain, less blood loss, smaller incisions, less time in the hospital and faster recovery.


Robotic surgery

Dr. Weerasinghe is highly skilled in performing many procedures utilizing the latest robotic surgical assurance platform at HCA Florida Trinity Hospital. This robotic surgery system combines unprecedented pre-operative planning tools and analytics with unparalleled intra-operative guidance, giving patients the most advanced surgery options available.

Lose more than weight

In general, weight loss surgery has proven to be the most effective and long-lasting treatment for morbid obesity. According to the National Institutes of Health, bariatric surgery is the only proven weight loss method for those suffering from morbid obesity, defined as a body mass index (BMI) of 40 or more, or a BMI between 35 to 39 with comorbid conditions, such as diabetes, high blood pressure and sleep apnea.
