Hypertension is typically diagnosed when blood pressure consistently measures 130/80 mm Hg or higher. This threshold was lowered in recent guidelines to reflect a more proactive approach to managing high blood pressure. Blood pressure is categorised as follows: Normal: Less than 120/80 mm Hg, Elevated: 120-129/<80 mm Hg, Hypertension Stage 1: 130-139/80-89 mm Hg, Hypertension Stage 2: 140/90 mm Hg or higher. These guidelines help identify individuals at risk and guide healthcare providers in recommending appropriate lifestyle changes and, if necessary, medication to manage blood pressure effectively.
