  • According to the American Society for Metabolic and Bariatric Surgery (ASMBS) multiple large studies have shown bariatric surgery to be an effective and durable treatment of morbid obesity. Surgeries work by changing the signals that regulate set points for body fat, a tool no traditional diet can provide. Also, studies show that more than 90% of bariatric patients are able to maintain a long-term weight loss of 50% excess body weight or more when combined with dietary and lifestyle changes.
  • Bariatric surgery significantly improves or resolves obesity related conditions, including type 2 diabetes, sleep apnea, hypertension, arthritis, asthma, acid reflux and more.
  • Large scientific studies have shown that severely obese people who chose bariatric surgery live longer than those who do not. Very good safety results are achieved by carefully preparing patients for surgery.
  • A happier and healthier you is more than just physical transformation. Studies have shown that self confidence and wellbeing are improved. Many people have improvement in physical mobility allowing them to enjoy their lives in a way that they had lost. Weight loss truly gives people a new lease on life.


All surgeries carry some risk. Pneumonia, blood clots, infection, bleeding, leaking at staple lines, as well as ulcers, hernia and gallstones may occur, but are infrequent. Generally, the risks associated with weight loss surgery are significantly less than the risk of remaining morbidly obese. Your Bariatric Coordinator and surgeon are there for you to answer questions and assist you throughout your weight loss journey.

Patient results may vary. Consult your physician about the benefits and risks of any surgical procedure or treatment.
