Assessing Your Needs to Help You Reach Your Healthy Weight

Losing weight can be a difficult battle to fight, and if diet and exercise aren’t getting you closer to your goals, medical weight loss may be the right choice. At AdventHealth Tampa, formerly Florida Hospital Tampa, our compassionate, bariatric specialists have offered highly personalized care to the local Tampa community for decades. To determine if a medical weight-loss procedure is right for you, we’ll look together at factors like your age, your history, any previous attempts at weight loss, any related health conditions, and your body mass index (BMI).

If you meet the following conditions, you could be a candidate for our program at AdventHealth Tampa Bariatric and Metabolic Institute:

  • You are at least 18 years of age.
  • You have a Body Mass Index (BMI) of 40 (approximately 100 pounds over ideal body weight for men and 80 pounds over ideal body weight for women) or a BMI of 35 or above, with an associated condition such as diabetes, hypertension, sleep apnea, or obesity-related heart disease.
  • You have previously attempted weight loss in a program supervised by a physician, dietitian, or nutritionist.
  • You have a willingness to commit to long-term medical follow up, as well as the life-long changes in eating, exercise, and lifestyle habits necessary to maintain weight loss after surgery.

Personalized Care in Our Bariatric and Metabolic Institute

At AdventHealth Tampa, we understand that you’re an individual, and that is reflected in your unique weight-loss story. With tailored, personalized care, we'll determine whether you’re a good candidate for our advanced, minimally invasive surgical weight-loss procedures. Then, we’ll develop a treatment plan that fits your exact needs and concerns.

Some of the minimally invasive surgical treatments we offer at the Bariatric and Metabolic Institute include:

  • Laparoscopic or Robotic Roux-en-Y Gastric Bypass
  • Laparoscopic or Robotic Sleeve Gastrectomy
  • Robotic Revision Surgery

Each of these procedures is different, but all work to help control your appetite and diet by affecting your feelings of hunger and satisfaction. Some of the benefits of our advanced options — including precise, robot-assisted bariatric surgeries — include faster healing times, minimal scarring, and a quicker return to the life you love. Our caring, compassionate team will be with you at every step with support to help you achieve and maintain a healthy weight for the months and years to come.
