Hypertension is a common but serious condition that often has no symptoms, making it crucial to get blood pressure checked regularly. Untreated hypertension increases the risk of heart attack, stroke, kidney failure, and vision problems.Resistant hypertension and the kidneys are closely linked, as chronic kidney disease (CKD) is a major cause of resistant hypertension, and uncontrolled hypertension can lead to further kidney damage. This happens because the kidneys' ability to regulate blood pressure is impaired due to factors like fluid retention, excessive activation of the renin-angiotensin-aldosterone system (RAAS), and increased sympathetic nerve activity. Treating resistant hypertension in patients with kidney disease often requires careful management of sodium intake, medication adjustments, and potentially novel therapies like renal denervation.
