While the majority of hypertension are due to increasing age and genetic factors (termed essential hypertension), a significant proportion of hypertension, especially those that are difficult to control, are due to an underlying hormonal conditions. All patients with hypertension developing before the age of 40, or those with difficult hypertension, should have these hormonal causes properly evaluated.
