An observational descriptive cross-sectional study was conducted to evaluate the causes of oligomenorrhoea and secondary amenorrhoea among women between 20 to 40 years of age attending Gynaecology OPD. Total 250 patients who met the inclusion criteria were included in the study and divided into two groups: Group A (200 patients with oligomenorrhoea) & Group B ( 50 patients with secondary amenorrhoea). Most of the study population in both groups belonged to the 30-35 years age group. The difference in the mean age of the study population in both groups was not statistically significant (p=0.461).
