The term "postpartum complications" describes health issues that arise in the woman after giving birth, usually within the six weeks known as the "puerperium period," though some issues may continue or manifest after that time. These problems might entail systemic, psychological, or physical health issues and range in severity from minor to life-threatening. Improving maternal outcomes requires an understanding of their genesis, prevalence, and management.
