Aims: To study the histopathological changes of endometrium in Abnormal uterine bleeding and to study incidence among different age groups. Settings and Design: This study is a retrospective descriptional study done in the Pathology laboratory for two years from January 2016 to December 2017. Methods and Material: All the Data regarding the patient is collected from the Pathology records. Cases with known structural causes were excluded from the study. Statistical Analysis used: Results were analysed in the form of percentages. Results: A total number of 184 cases were included in the study. The most common age group for abnormal uterine bleeding was 41–50 yrs. The most common finding was the proliferative phase, followed by simple hyperplasia and secretory phase.
