High blood pressure, or hypertension, is a common condition where the force of blood against artery walls is persistently elevated. It often develops over many years and may not show obvious symptoms, making regular checks important. Left untreated, hypertension increases the risk of heart disease, stroke and kidney problems. Management includes lifestyle changes such as reducing salt intake, maintaining a healthy weight, increasing activity and stopping smoking, alongside recommended medication when necessary. Regular reviews with healthcare professionals and consistent home monitoring improve control and reduce complications.
