Energy balance
Bariatric surgery effectively treats obesity by reducing stomach volume and nutrient absorption, and inducing faster satiety.
For severely obese individuals, bariatric surgery is a viable option that mechanically restricts food intake and alters satiety signals. It is typically reserved for cases where lifestyle changes have not been sufficient.
GoodSupportsHIGH confidence
Bariatric surgeries may be performed in overtly obese patients to lessen stomach volume and nutrient absorption, and induce faster satiety.
Why this rating
Supported by general medical consensus and cited literature on surgical outcomes.

- Obesity is primarily driven by excessive energy intake and physical inactivity, mediated by impaired central brain circuit regulation and neuroendocrine hormone dysfunction.Strong
- Peripheral hormones (leptin, insulin, ghrelin, PYY, GLP-1, CCK) regulate appetite and energy balance by acting on the hypothalamus and brainstem, with resistance to these hormones contributing to obesity.Good
