Hypertension | What are the types of hypertension?

Hypertension is currently one of the most common clinical diseases. We often hear about essential hypertension, pregnancy-induced hypertension, etc. 

So how are hypertension classified and what types are there?

The most common clinical types of hypertension are classified according to the cause, including primary and secondary.

Secondary hypertension has a clear cause. If these causes are removed or controlled, blood pressure will return to normal. Therefore, the most important thing for this type of hypertension is to find the cause. Secondary hypertension can be divided into endocrine, renal, pregnancy, sleep apnea, and so on. The lesions of endocrine hypertension are mainly the adrenal glands, while renal hypertension is caused by renal vascular stenosis or glomerular and renal tubular lesions. Hypertension during pregnancy is hypertension that occurs during pregnancy, and apnea is caused by When sleeping, the respiratory tract is blocked, blood oxygen saturation is reduced, and hypertension is caused by sympathetic nerve excitement.

There is no clear cause is essential hypertension. Essential hypertension is the most common clinically, and its proportion is more than 90%. The risk factors include increasing age, eating too salty, staying up late, smoking, alcoholism, high blood sugar, high blood fat, and so on. A review of the literature found that some experts classified primary hypertension into adolescent metabolic, sympathetic hyperexcitability of the young and middle-aged, and ischemic nephropathy with significant stenosis of the non-renal artery.

In addition to classification according to the cause, hypertension can also be classified into high dynamic type, high volume type, and high impedance type according to different antihypertensive drugs. Of course, no matter what type of hypertension, blood pressure reduction is urgent, but different types of hypertension lower blood pressure methods and selected drugs may be slightly different.
