Women living with HIV/AIDS (WLWHA) encounter substantial systemic barriers that hinder their well-being and access to necessary services. These hindrances encompass gender disparities, limited healthcare availability, and societal stigma. Using Keynesian economic theory as a framework, this conceptual paper explores the impediments WLWHA face in accessing comprehensive HIV treatment services. Between January and June 2023, the authors conducted a comprehensive review of 100 scholarly articles to gain an understanding of the systemic barriers limiting access to essential HIV treatment and care for WLWHA. These barriers include gender-based violence, economic constraints, and healthcare system deficiencies. To address these challenges, a multi-faceted approach is needed, involving healthcare system reforms, economic empowerment, and educational initiatives. Keynesian economic theory, emphasizing government intervention to promote economic growth, offers valuable insights into addressing the systemic inequities faced by WLWHA. Improvement in healthcare access, education, and economic opportunities can create a more equitable society where everyone can access vital resources regardless of their health status. This paper underscores the urgency of tackling these systemic barriers and provides practical recommendations for policymakers and stakeholders to enhance the availability of crucial pharmaceuticals for WLWHA, thereby advancing health equity and social justice.
