Abstract

Excess weight gain contributes to increased blood pressure in most patients with essential hypertension. Although the mechanisms of obesity hypertension are not fully understood, increased renal sodium reabsorption and impaired pressure natriuresis play key roles. Several mechanisms contribute to altered kidney function and hypertension in obesity, including activation of the sympathetic nervous system, which appears to be mediated in part by increased levels of the adipocyte-derived hormone leptin, stimulation of pro-opiomelanocortin neurons, and subsequent activation of central nervous system melanocortin 4 receptors.

  • Leptin increases sympathetic nerve activity by binding to leptin receptors in the central nervous system and contributes to obesity-induced hypertension.

    “In addition to regulating energy stores, leptin increases sympathetic nerve activity (SNA) by binding to leptin receptors (LepRs) in the CNS and contributes to obesity-induced hypertension6,121,122.”
  • The role of the sympathetic nervous system in linking obesity with elevated blood pressure has been well documented in experimental models and in humans.

    “The role of the SNS in linking obesity with elevated BP has been well documented in experimental models and in humans121,152.”
  • Some rodent models of obesity, such as those with MC4R or leptin gene mutations, have normal or reduced SNS activity and decreased BP despite inflammation, insulin resistance, dyslipidemia, and other metabolic changes associated with obesity.

    “Therefore, some rodent models of obesity, such as those with melanocortin 4 receptor (MC4R) or leptin gene mutations, have normal or reduced SNS activity and decreased BP despite inflammation, insulin resistance, dyslipidemia, and other metabolic changes associated with obesity17.”
  • Obesity generally decreases parasympathetic tone and increases sympathetic activity.

    “Obesity generally decreases parasympathetic tone and increases sympathetic activity.”
  • Leptin and the CNS POMC pathway appear to be important in obesity-induced SNS activation and hypertension.

    “Although the role of many of these factors is still uncertain, leptin and the CNS POMC pathway appear to be important in obesity-induced SNS activation and hypertension17,80–82.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
