Untreated high blood pressure shortens life expectancy by about 5 years on average compared to normal levels, based on long-term studies like Framingham.
Key Lifespan Data
People with hypertension at age 50 lose roughly 5.1 years for men and 4.9 for women versus normotensives, due to cumulative heart, stroke, and kidney damage.
Stage 1 hypertension raises lifetime CVD risk by 36%, accelerating if it progresses; treatment normalizes this gap.
Factors Affecting Survival
Younger people or those with mild cases might live decades asymptomatically, but risks compound: 2-3x heart attack odds in 10 years untreated. Genetics, smoking, and obesity worsen it—control adds years back. Check BP regularly; meds/lifestyle prevent loss.
