[Pain sensitivity in obese individuals]

A Pradalier, J C Willer, J Dry

    Annales De Medecine Interne
    |January 1, 1982
    PubMed
    Summary

    Obese women have a significantly lower pain threshold compared to controls. Increased weight correlates with a reduced nociceptive reflex threshold, suggesting potential issues with the body's natural pain-relief system.

    Area of Science:

    • Neuroscience
    • Physiology
    • Obesity Research

    Context:

    • Obesity is a complex metabolic condition.
    • Pain perception can be altered in obesity.
    • The endogenous opioid system plays a role in pain modulation.

    Purpose:

    • To investigate the nociceptive threshold in obese women.
    • To explore the relationship between body weight and pain sensitivity.
    • To hypothesize about the involvement of endogenous pain-control systems in obesity.

    Summary:

    • The study measured the nociceptive threshold using the saphenobicipital reflex method in 30 obese women and 20 controls.
    • Obese women exhibited a significantly lower nociceptive reflex threshold (6.57 ± 3.52 mA) compared to controls (9.42 ± 1.90 mA).
    • A significant inverse correlation was found between the degree of overweight and the nociceptive reflex threshold.

    Impact:

    • Findings suggest altered pain processing in obese individuals.
    • The results point towards a potential dysfunction in the endogenous morphine-like system in human obesity.
    • This research may inform future studies on pain management and metabolic interventions for obesity.
