Hypertension is a common medical disorder in pregnancy that may predate or first appear in pregnancy. Endocrine disorders rarely are the cause of the elevated blood pressure. However, it is essential to have a high index of suspicion because they carry much higher fetal and maternal morbidity and mortality risks. Endocrine disorders presenting as hypertension are primarily the result of autonomous production of renin, aldosterone, cortisol, or catecholamines. This report discusses the physiological changes in pregnancy, presentation, investigation, and management of these disorders.
