Thyroid dysfunction, specifically subclinical hyperthyroidism, may contribute to dysfunctional uterine bleeding in women. Further research is needed to confirm the link between thyroid hormones and heavy menstrual bleeding.

Area of Science:

  • Endocrinology
  • Gynecology

Background:

  • Dysfunctional uterine bleeding (DUB) is a common gynecological issue.
  • The role of thyroid function in DUB is not fully understood.

Purpose of the Study:

  • To assess thyroid gland function in women with DUB.
  • To investigate potential links between thyroid hormones and menorrhagia.

Main Methods:

  • Compared 40 women with menorrhagia to 20 healthy controls.
  • Measured serum levels of thyroid-stimulating hormone (TSH), triiodothyronine (T3), thyroxine (T4), and prolactin.

Main Results:

  • Significant differences in TSH, total and free T3, and total and free T4 levels were found between groups.
  • Elevated prolactin levels were observed in women with menorrhagia.

Conclusions:

  • Subclinical hyperthyroidism may be a risk factor for DUB.
  • Further studies are required to validate these findings and explore the relationship between thyroid status and uterine bleeding.
