Why Your High Blood Pressure Diagnosis Might Be Wrong—and How to Check Properly

Many people diagnosed with high blood pressure may not actually have hypertension. The condition often goes unnoticed because it rarely shows symptoms. Doctors now recommend regular checks and careful monitoring to avoid misdiagnosis.

For accurate blood pressure readings, patients should sit quietly with the cuff placed on a bare upper arm at heart level. Measurements must be taken on both arms, with three readings per arm, averaging the second and third results.

To confirm true hypertension, a seven-day diary is advised, recording morning and evening readings. If levels consistently stay near 135/85 mmHg, hypertension is unlikely, though further tests may still be needed.

People under 40 should check their blood pressure every three years, while those over 40 need annual monitoring. More frequent checks may be required if heart or vascular issues are suspected.

High blood pressure can sometimes stem from other conditions. Obstructive sleep apnoea, thyroid disorders, and menopausal changes are common non-cardiac causes. Migraines or chronic pain may also trigger spikes, making standard hypertension treatments less effective.

Regular and precise blood pressure monitoring helps avoid unnecessary treatment. Understanding the underlying causes of spikes ensures better management. Doctors stress the importance of following guidelines to distinguish true hypertension from temporary rises.
