Context: Women are the most vulnerable in any disastrous situation compared to their male counterpart. It is evident in several studies that among all other natural disasters flood causes immense sufferings for women especially in respect to their Sexual and Reproductive Health (SRH) due to the lower standard of living condition and poor institutional response. Aims: The objective of this study was to understand the reproductive health status of women during the flood. The study also aimed to explore the effectiveness of existing reproductive health care services for women and adolescents during the flood. Methods and Material: We used both qualitative and quantitative method in this study and our sampling procedure was purposive. We used a semi-structured questionnaire to collect data from 46 women in six villages under three different districts of Bangladesh, namely- Faridpur, Shariatpur and Sirajgonj. Moreover, five focus group discussion with the vulnerable women, ten exit interviews of the health care seeking women and five key informant interviews’ of the local health care providers were conducted. Besides, unstructured observation (both participatory and non-participatory) was also conducted in the studied communities. Results: Findings of this study revealed that during flood women suffered more from leucorrhoea TID, pregnancy-related complexity, urinary infection and malnutrition compared to normal time. In contrast, poor responses by the institutions entitled to mitigate disaster-induced vulnerability enhanced sufferings of the victims. Conclusion: Strengthening women-friendly disaster management program and enhancing institutional governance might be effective to reduce women’s SRH vulnerability during a flood.
