Which condition is NOT a common cause of hypertension?

Infectious disease is not typically considered a common cause of hypertension. While certain infections can lead to temporary increases in blood pressure due to factors like pain, stress, or increased metabolic demands on the body, they generally do not lead to chronic hypertension. Chronic hypertension is often associated with conditions that have a more direct and sustained impact on cardiovascular function and blood pressure regulation.

The other options provided are well-established contributors to hypertension. Obstructive sleep apnea, for example, has been linked to disrupted sleep and increased sympathetic nervous system activity, which can result in elevated blood pressure. Idiopathic hypertension refers to high blood pressure with no identifiable cause, which is common in the general population. A high sodium diet is also known to raise blood pressure due to its effects on fluid retention and vascular resistance. These factors are more directly tied to the mechanisms that regulate blood pressure, making them prevalent causes of hypertension.
