The most common cause of secondary hypertension?

Secondary hypertension comes from an identifiable condition, unlike essential hypertension. Among the various identifiable causes in adults, chronic kidney disease is the most common. Damaged kidneys struggle to excrete salt and water, leading to volume overload, and they often overactivate the renin-angiotensin-aldosterone system and sympathetic pathways. This combination drives higher blood pressure. Other causes like sleep apnea, pheochromocytoma, or renal artery stenosis can raise blood pressure, but they are less common overall compared with CKD. Sleep apnea is a frequent contributor, but CKD more commonly underlies secondary hypertension in the general adult population.
