Several hematologic problems develop or get triggered during the pregnancy period. This can be even prompted by certain normal physiologic changes that occur during pregnancy state, causing alterations in hematologic profiles. These hematological disorders are the key significant source of morbidity and mortality occurring during pregnancy, having severe implications for both mother and the fetus. Proper understanding of the cause, diagnostic strategy, and management of such disorders are of much importance. Further studies should be conducted to decrease the prevalence of these hematological disorders during pregnancy to avoid their risks on mothers and their new-born infants.
