Like any other surgical procedure, bariatric surgery too has its share of pros and cons. For people who do not suffer from morbid obesity, the pros of bariatric surgery overshadow its negatives.

Some of the advantages of weight loss surgery are:

Weight Loss

Bariatric patients benefit from weight loss success in the long run. According to the American Society for Metabolic and Bariatric Surgery (ASMBS), over 90% of severely obese bariatric patients are able to keep off 50% or more of the excess weight lost successfully. Among the morbidly obese, nearly 80% of them are able to keep of more than half of the weight loss in the long run.

Better Health and Resolution of Co-morbidities

Reduction in mortality rates after bariatric surgery is a direct outcome of the resolution of the co-morbidities of obesity. Some of the health conditions that can be aggravated by obesity but which get resolved in bariatric patients are:

  • Hypertension or High Blood Pressure (HBP)
    Increased Longevity after Bariatric Surgery

  • Asthma
  • Non-alcoholic Fatty Liver Disease
  • Polycystic Ovary Syndrome (PCOS)
  • Stress Incontinence
  • Gastroesophageal Reflux Disease (GERD)
  • Arthritis

Increased Longevity

According to a Study by Stacy A. Brethauer published in the Cleveland Clinic Journal of Medicine, individuals with a BMI of 45 or more in their 20s have a life expectancy shorter by 13 years. However, there are a number of observational studies which point that people who have undergone bariatric surgery have lower mortality rates than individuals who have not had surgery at all.
