Final answer:
Hypertension is a chronic medical condition defined by persistently elevated blood pressure. It often goes unnoticed due to the lack of symptoms. Without proper management, hypertension can lead to serious cardiovascular complications.
Step-by-step explanation:
Hypertension is a chronic medical condition characterized by persistently elevated blood pressure in the arteries. Normal blood pressure ranges from less than 120/80 mm Hg, while hypertension is diagnosed when blood pressure consistently measures at 140/90 mm Hg or above. Hypertension often does not cause symptoms, leading many individuals to be unaware of their condition. Without proper management and treatment, hypertension can increase the risk of heart attacks, strokes, aneurysms, peripheral arterial disease, chronic kidney disease, and heart failure.
