Mean age was 29.57 ± 8.27 years. Large numbers of respondents came from urban area (58%). On evaluation of types & causes of AUB, maximum patient belongs to AUB-L (leiomyoma) group (53%) followed by AUB-A (adenomyosis) (28%); AUB-P (polyp) (8%); AUB-O (ovulatory) (9%) and AUB-M (malignancy) (2%). Present study showed that prevalence of thyroid disorders is 26% in AUB patients. The prevalence of Hypothyroidism was 18% and Hyperthyroidism was 8%.
