    Current oral contraceptive users show higher glucose, insulin, triglyceride, and blood pressure levels. These adverse physiological changes associated with oral contraceptives are reversible upon discontinuation.

    Area of Science:

    • Endocrinology
    • Metabolic Health
    • Cardiovascular Physiology

    Background:

    • Oral contraceptives (OCs) are widely used by women of reproductive age.
    • Understanding the physiological impact of OCs is crucial for women's health.
    • Previous studies have suggested potential metabolic alterations associated with OC use.

    Purpose of the Study:

    • To compare physiological variables in women who never used, formerly used, and currently use oral contraceptives.
    • To investigate the association between current oral contraceptive use and metabolic and cardiovascular markers.
    • To determine if observed physiological changes are reversible after discontinuing oral contraceptive use.

    Main Methods:

    • Cross-sectional study comparing three groups of women (never, past, current OC users) aged 30-59 years.

  • Blood samples analyzed for glucose, insulin, cholesterol, and triglyceride levels.
  • Postchallenge glucose and insulin response quantified using summed values (G-CON and I-CON).
  • Systolic blood pressure measured in all participants.

    • Main Results:

    • Current OC users exhibited significantly higher G-CON, I-CON, triglyceride, and systolic blood pressure compared to never users.
    • Current OC users also showed significantly higher summed glucose, G-CON, and I-CON than past users.
    • These findings indicate adverse physiological changes associated with current oral contraceptive use.

    Conclusions:

    • Current oral contraceptive use is linked to unfavorable changes in glucose metabolism, insulin response, lipid profiles, and blood pressure.
    • The observed physiological alterations appear to be reversible after cessation of oral contraceptive use.
    • This study highlights the importance of monitoring these parameters in women using oral contraceptives.
