WeightControl.com:  What is the background for this study?  What are the main findings?

Response: ‚ÄčObesity is a burgeoning problem in the USA and globally. It is estimated that over $100 billion are spent in healthcare expenditures each year on those patients with fatty liver disease related to obesity-induced problems.

Lifestyle modification is very difficult to achieve on a sustained basis. Insurance companies have strict criteria for bariatric surgery. Our study of a database of over 100 million lives spanning the years of 2007 to 2017 showed a marked reduction in all malignancies after bariatric surgery and particularly in obesity-related cancers such as colorectal, esophageal, pancreatic, ovarian, uterine, postmenopausal breast and kidney cancers.

WeightControl.com: What should readers take away from your report?

Response: Maintaining a normal weight is an important factor in health. Obesity increases the risk of malignancy. This is the first study to quantify the marked reduction in malignancy risk achieved through weight loss via bariatric surgery.

WeightControl.com: What recommendations do you have for future research as a result of this work?

1. Is there a critical amount of weight reduction?

2. Are there demographic variables of importance such as race,ethnicity, gender?

3. Are there greater benefits in older people who are more prone to malignancy?

There was no external funding for this research. None of the authors have any relevant disclosures.
