Weight loss surgery

Enjoy the life you were meant to have. Take our quick assessment to help determine if weight loss surgery is right for you.


Enjoy the life you were meant to have.

Imagine finding your way to a better life—one where you can play with your kids or go out with friends and actually enjoy yourself because you feel better. If you feel now is the time to commit to living a healthier life, weight loss surgery may be what you need.

What is weight loss (bariatric) surgery?

Weight loss surgery, also known as bariatric surgery, is a medical procedure used to treat obesity by limiting the amount of food a patient can eat, changing how the body absorbs food, and altering the digestion process.

What is medical weight loss?

Medical weight loss is a specialized program that offers a comprehensive approach to weight loss under the guidance and supervision of trained healthcare professionals. This approach is customized to each individual's specific needs and is designed to address the underlying causes of obesity, which can include factors such as genetics, lifestyle, and medical conditions. The benefits of medical weight loss go beyond just shedding excess pounds. It can also improve overall health, reduce the risk of chronic diseases such as diabetes, and increase quality of life. Additionally, medical weight loss programs offer ongoing support and education to help individuals achieve and maintain their weight loss goals.


Am I a candidate?

If you have already gone through the gamut of diet, exercise, and sacrifice without achieving significant, sustainable weight loss, bariatric surgery such as gastric bypass or sleeve gastrectomy may be the answer. 

Bariatric surgery is not cosmetic and should not be considered based on simply "looking better." There are risks with any surgery, so this alternative should be an option only after serious discussion with your physician to determine: 

  • If surgery is the right treatment for you 
  • If you are mentally and emotionally prepared to make lifelong lifestyle changes
  • If you have the support system you need to succeed

Everyone is different, but weight loss surgery could be an option for you if you: 

  • Are more than 100 pounds over your ideal body weight
  • Have a BMI of 40 or above
  • Have tried multiple weight loss programs without lasting success
  • Would like to lose weight for health reasons 

Take our quick assessment to find out if weight loss surgery is right for you.

It only takes a few minutes and can help you determine risk factors and the impacts of excess weight on quality of life.

Medical benefits of weight loss

Though feeling better is a usually a desired goal of weight loss, other medical benefits may also include:

  • Reduced blood pressure
  • Reduced risk of diabetes
  • Decreased risk of heart disease and stroke
  • Reduced joint and tendon problems
  • Improvement with obstructive sleep apnea
  • Decreased cancer risk
  • Improved fertility

Recovering from weight loss surgery

Recovery time is 2-4 weeks, depending on the individual and their lifestyle. You will stay in the hospital for one night after surgery, and then return to normal activity within two to three weeks. Weight loss typically continues for about a year and then abates. You should use the first year to develop good eating and exercise habits that will keep you from regaining weight. Many weight-related health problems improve or even disappear after bariatric weight loss surgery, including diabetes, high blood pressure, asthma, and obstructive sleep apnea
