Bariatrics is the branch of medicine that deals with the causes, prevention, and treatment of obesity. The term bariatrics was created around 1965, from the Greek root bar- ("weight," as in barometer), suffix -iatr ("treatment," as in pediatrics), and suffix -ic ("pertaining to"). The field encompasses dieting, exercise and behavioral therapy approaches to weight loss, as well as pharmacotherapy and surgery. The term is also used in the medical field as somewhat of a euphemism to refer to people of larger sizes without regards to their participation in any treatment specific to weight loss, such as medical supply catalogs featuring larger hospital gowns and hospital beds referred to as "bariatric."
Overweight and obesity are rising medical problems. There are many detrimental health effects of obesity: Individuals with a BMI (Body Mass Index) exceeding a healthy range have a much greater risk of medical issues. These include heart disease, diabetes mellitus, many types of cancer, asthma, obstructive sleep apnea, and chronic musculoskeletal problems. There is also a focus on the correlation between obesity and mortality.
Overweight and obese people, including children, may find it difficult to lose weight on their own. It is common for dieters to have tried fad diets only to find that they gain weight, or return to their original weight, after ceasing the diet.
Although diet, exercise, behavior therapy and anti-obesity drugs are first-line treatment, medical therapy for severe obesity has limited short-term success and very poor long-term success. Weight loss surgery generally results in greater weight loss than conventional treatment, and leads to improvements in quality of life and obesity related diseases such as hypertension and diabetes mellitus. The combination of approaches used may be tailored to each patient. Bariatric treatments in youth must be considered with great caution and with other conditions that may not have to be considered in adults.
