Hypertension, or high blood pressure, is a chronic medical condition in which the blood pressure in the arteries is persistently elevated. It often develops silently over time and may not show any symptoms until serious complications arise. If left uncontrolled, it can lead to heart disease, stroke, kidney damage, and other serious health issues. Risk factors include a sedentary lifestyle, poor diet, obesity, smoking, excessive salt intake, and stress. Management typically involves lifestyle changes such as regular exercise, a balanced diet, limiting alcohol, and medication as prescribed by a doctor.
