Introduction Excessive vaginal discharge is troublesome for females. The majority of the women seek gynecological consultation due to excessive vaginal discharge. The causes vary from physiological to pathological discharge. Unless the cause is identified and treated, women will remain in distress. The present study was thus carried out to determine the most common cause of the excessive vaginal discharge. Methods A cross‐sectional study was conducted at the Phuentsholing General Hospital, Chukha, Bhutan, from May 1 to October 31, 2021. All females aged 18 years and older, irrespective of marital status, who presented with excessive vaginal discharge were recruited for the study. With due informed consent, a sterile speculum examination was performed and a high vaginal swab was collected and subjected to various tests. The data collected were analyzed using SPSS 23 software. Descriptive statistical tests were used for frequencies, percentages, mean, and standard deviations; the χ 2 test was used to determine associations, and a logistic regression test was performed to determine the effect of independent variables on dependent variables. Results A total of 400 women were recruited for the study, of whom 362 (90.5%) women had infective causes for vaginal discharge. Trichomoniasis was the most common infection identified in 162 (40.5%) women, followed by bacterial vaginosis (91, 22.8%) and vulvovaginal candidiasis (52, 13.0%). In 38 (9.5%) women, infective cause was not found and categorized as physiological vaginal discharge. Malodorous, profuse discharge, vulval itching, dyspareunia, dysuria, and lower abdominal pain were significantly associated with infectious vaginal discharge. Conclusions Excessive vaginal discharge was mainly caused by infections. The most commonly detected infection was trichomoniasis, followed by bacterial vaginosis and vulvovaginal candidiasis. Every female with vaginal discharge requires proper evaluations to identify the infection and treat it adequately.
