Bariatrics is the branch of medicine dealing with obesity. Paul Jones

Note: According to the blog ConscienHealth (conscienhealth.org), August 1, 2015, the word bariatrics was coined by the physician Raymond E. Dietz in 1961. The professional organization with which he was associated, formed as the National Obesity Society in 1950, later became the National Glandular Society, then the American College of Endocrinology and Nutrition, and the American Society of Bariatrics by 1963 (later the American Society of Bariatric Physicians, then the Obesity Medicine Association in 2015). The word bariatric can be found earlier in the name of a corporate entity, the Bariatric Corporation of Coral Gables, Florida, which introduced a weight reduction drug neo-barine in 1958 (withdrawn by order of the Food and Drug Administration in 1964). There appears to be no connection between the Bariatric Corporation and Raymond Dietz.
