Morbid obesity may lead to many life-threatening health problems, known as co-morbidities, and a shorter life. Research has shown that weight-loss surgery can help in both areas:

Studies show that bariatric surgery can improve and resolve many weight-related health conditions1 including:

  • Type 2 diabetes
  • Hypertension
  • High cholesterol
  • Sleep apnea

Studies show that the risk of an early death for those struggling with obesity is twice that of a non-obese person2

  • With treatment, there is a better chance for a longer life
  • A clinical study shows that gastric bypass surgery reduces mortality in patients with severe obesity by 89 percent over 5 years3

In addition, after weight-loss surgery, patients consistently report4

  • A decrease in depression and anxiety
  • Improved self esteem
  • A higher quality of life
