Summary of Hypertension- causes, symptoms, diagnosis, treatment, pathology
Hypertension, or high blood pressure, affects over a billion people worldwide and can lead to serious health problems like heart disease and strokes. It is defined by two numbers, systolic and diastolic blood pressure, with normal readings below 120/80 mmHg. Hypertension is often asymptomatic, earning it the nickname "silent killer." The classification of hypertension includes normal, stage 1, and stage 2 categories. Treatment involves lifestyle changes such as diet, exercise, and stress reduction, along with medication when necessary.
