Benign hypertension or benign essential hypertension are medical terms now considered obsolete, but once used to describe mild to moderate hypertension (high blood pressure). These historical terms are considered misleading, [1] as hypertension is never benign. Coonsequently, the terms have fallen out of use (see history of hypertension).
Essential hypertension (also called primary hypertension, or idiopathic hypertension) is a form of hypertension without an identifiable physiologic cause. [1] [2] It is the most common type affecting 85% of those with high blood pressure. [3] [4] The remaining 15% is accounted for by various causes of secondary hypertension. [3]
Idiopathic intracranial hypertension (IIH), previously known as pseudotumor cerebri and benign intracranial hypertension, is a condition characterized by increased intracranial pressure (pressure around the brain) without a detectable cause. [2] The main symptoms are headache, vision problems, ringing in the ears, and shoulder pain.
The latest statistics suggest that nearly half of Americans have hypertension with a systolic pressure greater than 130 or a diastolic pressure greater than 80. This is referred to as Stage 1 ...

Hypertension is slightly more frequent in men. [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]
However, possible medical causes, such as medications, kidney disease, adrenal problems or thyroid problems, must first be excluded. High blood pressure that develops over time without a specific cause is considered benign or essential hypertension. Blood pressure also tends to increase as a person ages.
Labile hypertension occurs when there are unexpected changes in blood pressure. The term can be used to describe when people have blood pressure measurements that abruptly fluctuate from being abnormally high, approximately 140/90 mm Hg or over and returns to its normal range.
