Causes of Hypertension

The common causes of hypertension at different ages are given in Table 22-22. A more comprehensive list of the causes of hypertension is given in Tables 22-23 and

22-24.

For convenience these have been divided into hypertension that is associated with another, usually obvious disease (Table 22-23), is often acute, and subsides when the associated disease is cured, and sustained hypertension that often cannot be diagnosed by a preliminary history and examination and is usually secondary to renal or endocrine disorders (

Table 22-24).
