This review examines the mechanisms by which hypoxia induces inflammation, focusing on the role of hypoxia-inducible factors (HIFs) in regulating pro-inflammatory cytokines and the subsequent immune response. The placenta, as a central organ in pregnancy, is particularly affected by hypoxia-induced inflammation, which can impair its function and lead to complications such as preeclampsia, preterm birth, and gestational diabetes mellitus. The interplay between hypoxia and inflammation has profound implications for maternal health, as these processes can disrupt normal physiological adaptations during pregnancy and lead to long-term health consequences. Preeclampsia, characterized by hypertension and organ dysfunction, is closely linked to hypoxia-induced inflammation, resulting in endothelial dysfunction and increased cardiovascular risk. Additionally, the inflammatory response to hypoxia is associated with preterm birth and gestational diabetes, both of which pose immediate and long-term risks to both the mother and the child. Keywords: Hypoxia, Inflammation, Maternal Health, Pregnancy, Immune Response Introduction Maternal health is a critical determinant of pregnancy outcomes, influencing both the short-term and long-term well-being of mothers and their children. Healthy pregnancies are characterized by the absence of complications that can jeopardize the health of the mother and the developing fetus. However, various factors can adversely affect maternal health, one of which is hypoxia—a condition where there is insufficient oxygen supply to tissues. Hypoxia can arise from multiple sources, including placental insufficiency, maternal anemia, and environmental factors such as high altitude. 1-2 Hypoxia occurs when the oxygen supply to tissues is inadequate to meet metabolic demands. During pregnancy, hypoxia can arise from various physiological changes, including increased oxygen consumption by the growing fetus and placenta. The body typically responds to hypoxia through adaptive mechanisms that include the activation of hypoxia-inducible factors (HIFs), which regulate the expression of genes involved in oxygen homeostasis, angiogenesis, and inflammation. However, prolonged or severe hypoxia can overwhelm these adaptive responses, leading to cellular dysfunction and the activation of inflammatory pathways. This dysregulation can have detrimental effects on maternal health and fetal development. 3-4 The body’s response to
