Introduction: Thyroid dysfunction may have profound effect on the female reproductive system. Hypothyroidism results in change in cycle length and amount of bleeding leading to oligomenorrhea, amenorrhea, polymenorrhea, and menorrhagia Objective: This study was conducted to see menstrual patterns in hypothyroid females of reproductive age group in Kashmir, Jammu & Kashmir. Study Design: Prospective cohort study Material and Methods: 50 patients who presented to OPD with complaints of abnormal uterine bleeding in Dept of Obstetrics & Gynaecology, SKIMS, Kashmir were recruited. Statistical Analyses: Data presented as percentages for qualitative variables. For continuous variable, student ‘t-test’ was applied and to see for association among the variables , chi-square test was used. P value less than 0.05 was considered as statistically significant. Results: In our study among hypothyroid reproductive women, most common pattern of AUB was menorrhagia that was around 58% (29/50) followed by polymenorrhea 22 % (11/50). Hypomenorhea, oligomenorrhea and amenorrhea were present in 8%, 6 % and 6 % respectively. Conclusion: In hypothyroid females presenting with AUB, menorrhagia is the most common abnormal pattern of bleeding followed by polymenorrhea. Hypomennorhea, oligomennorhea and amenorrhea were less common.
