[10] In people aged under 50 years, more men than women have hypertension, [10] and in ages above 50 years the prevalence of hypertension is the same in men and women. [10] In ages above 65 years, more women than men have hypertension. [7] Hypertension becomes more common with age. [5]
Essential hypertension (also called primary hypertension, or idiopathic hypertension) is a form of hypertension without an identifiable physiologic cause.

The prevalence of hypertension (blood pressure 140/90 or higher) in people aged 18 years or older was 19%—a 30% increase since 1991. The prevalence of adult overweight (23%) and obesity (7%) had increased by 39% and 97%, respectively, over a 10-year period. [6] Of particular note is the rapidly developing epidemic of obesity in Chinese children.

Guidelines on the choice of agents and how best to step up treatment for various subgroups in hypertension (high blood pressure) have changed over time and differ between countries. A Comparison of International Guidelines on Goal Blood Pressure and Initial Therapy for Adults With Hypertension (adapted from JNC 8 guidelines [ 1 ] )
Guidelines for treating resistant hypertension have been published in the UK [45] and US. [46] It has been proposed that a proportion of resistant hypertension may be the result of chronic high activity of the autonomic nervous system, known as "neurogenic hypertension". [47] Low adherence to treatment is an important cause of resistant ...
