###Human: What is the reason for recurrent nocturnal high blood pressure in a patient on anti-hypertensives? ###Assistant: HelIo. Nocturnal nighttime hypertension is a complication of primary secondary hypertension. It can lead to some cardiovascular complications. I usually treat my patients in this situation with Potassium supplements and advice that they avoid any sodium diet. Drugs like Losartan that block angiotensin receptors are some of the medications I advise. I advise her to see a cardiologist for proper evaluation, to know the best management possible in her case. I wish her a quick recovery.
