A Cross-Sectional Study on the Correlation Between Thyroid Dysfunction and Abnormal Uterine Bleeding in Women of Reproductive Age

Background: Abnormal uterine bleeding (AUB) is one of the most common gynecological complaints among reproductive-age women, often resulting from hormonal imbalances. Thyroid hormones play a crucial role in maintaining menstrual regularity and endometrial stability. This study aimed to assess the correlation between thyroid dysfunction and AUB patterns in women of reproductive age. Methods: A hospital-based cross-sectional study was conducted on 150 women aged 15-45 years presenting with AUB at a tertiary care center. Detailed clinical history, menstrual pattern, physical examination, and ultrasonographic findings were recorded. Serum T3, T4, and TSH levels were estimated using enzyme-linked immunosorbent assay (ELISA). Patients were categorized as euthyroid or having thyroid dysfunction (subclinical hypothyroidism, overt hypothyroidism, or hyperthyroidism). Data were analyzed using SPSS v25 with appropriate statistical tests, and p
