The postpartum period represents a critical and underexplored phase in the reproductive course of women with systemic autoimmune diseases (SAD). While advances in disease management have substantially improved pregnancy outcomes, the weeks and months after delivery remain associated with a significant burden of maternal complications. Abrupt immunological and hormonal changes, together with treatment modifications during pregnancy and breastfeeding, may predispose women with SAD to disease reactivation and other adverse outcomes after delivery. This Mini Review summarizes the available evidence on postpartum complications in women with SAD, with a focus on disease flares, thrombotic and infectious events, mental health and quality of life, and therapeutic challenges during lactation. Despite its clinical relevance, postpartum outcomes remain insufficiently investigated, with limited prospective data, heterogeneous endpoints, and gaps between clinical recommendations and real-life practice. Recognizing the postpartum period as a distinct and integral component of reproductive health is essential to improve maternal outcomes and optimize long-term care for women with SAD.
