Gastrointestinal disorders in pregnancy include preexisting and acquired diseases and pregnancy-induced changes to the gastrointestinal tract. Impact of each disorder ranges from life-threatening in need of emergent medical interventions and/or surgery to less acute disorders that affect quality of life and a patient’s ability to maintain adequate nutrition during pregnancy. OB/GYN hospitalists are often the first providers whom a patient sees on arrival to an obstetric emergency triage unit. OB/GYN hospitalists set the standard of care for these patients by leading a multidisciplinary team and following evidence-based recommendations. Core competencies for gastrointestinal disorders in pregnancy are arranged according to initial presenting complaints of nausea and vomiting, abdominal pain, changes in bowel movements, and intrahepatic cholestasis of pregnancy.
