This study investigates the menstrual hygiene practices and associated health issues among slum-dwelling women aged 12-50 years. A cross-sectional survey was conducted among 150 women, with 50 participants selected from each of three strata based on their menstrual hygiene practices: exclusive use of traditional cloth/cotton, exclusive use of sanitary pads, and a combination of both. The study reveals a significant reliance on traditional methods, with 42% using cloth/cotton, 21% using sanitary pads, and 37% employing a combination. Furthermore, deeply ingrained taboos surrounding menstruation persist, impacting women's daily lives. A significant portion of participants reported receiving initial information on menstruation from unreliable sources, potentially contributing to poor hygiene practices. The study also identifies various health issues linked to unhygienic menstrual management. This research highlights the urgent need for targeted interventions to improve menstrual health awareness and promote safe and hygienic practices among slum-dwelling women.
