What is the most common cause of secondary hypertension in young people?

The most common cause of secondary hypertension in young people is indeed endocrine disorders. In this age group, particularly adolescents and young adults, conditions such as primary hyperaldosteronism (Conn's syndrome), pheochromocytoma, and Cushing's syndrome are often implicated. Endocrine disorders often result in hormonal imbalances that lead to increased blood pressure due to mechanisms such as sodium retention, increased blood volume, and heightened vascular reactivity.

While sleep apnea is a recognized cause of hypertension, its prevalence is greater in middle-aged and older populations rather than in the young. Renal artery stenosis can cause secondary hypertension and is more commonly associated with older individuals or those with atherosclerotic disease. Medication side effects can contribute to elevated blood pressure, but typically in younger populations, the causes tend to be more inherent and related to underlying medical conditions, such as endocrine disorders. Thus, endocrine disorders stand out as the most prevalent cause in the younger demographic presenting with secondary hypertension.
