Background Menstrual hygiene management (MHM) is a recognised public health, social and educational issue, which must be achieved to allow the realisation of human rights. People with disabilities are likely to experience layers of discrimination when they are menstruating, but little evidence exists on this topic. Methods The study aims to investigate the barriers to MHM that people with a disability, and their carers, face in the Kavrepalanchok, Nepal, using qualitative methods. Twenty people with disabilities, aged 15 to 24, who menstruate and experience ‘a lot of difficult’ or more across one or more of the Washington Group functional domains were included, as well as 13 carers who provide menstrual support to these individuals. Two stages of purposive sampling and snowball sampling were applied to identify participants. We used different approaches to investigating barriers to MHM including: in-depth interviews, PhotoVoice and ranking, market survey of menstrual products and user preference with ranking, accessibility and safety audits of the water and sanitation facilities. We analysed data thematically, using Nvivo 11. Results Barriers to MHM experienced by people with disabilities differ according to the functional limitation. Inaccessible water, sanitation and hygiene facilities were a major challenge for people with mobility, self-care and visual limitations. People with intellectual impairments had difficulty accessing MHM information and their carers despaired when they showed their menstrual blood to others, which could result in abuse. No support mechanisms exist for carers for MHM and they felt overwhelmed and isolated. Menstrual discomfort was a major challenge; these were managed with home remedies, or not at all. Most participants followed menstrual restrictions, which were widespread and expected, for fear of being cursed if they did not. As disability is often viewed as a curse, this demonstrates the layers of discrimination faced. Conclusion Issues related to MHM for people with disabilities is more complex than for others in the population due to the additional disability discrimination and functional limitations experienced. Attention to, and resourcing for disability inclusive MHM must be prioritised for progress to be made towards the Sustainable Development Goals, which aims to ‘Leave No One Behind’.
