Silent Killer: High Blood Pressure's Hidden Dangers
28 Feb
Summary
- Nearly half of US adults have hypertension, with 11 million unaware.
- Untreated high blood pressure silently damages arteries and vital organs.
- Managing blood pressure through lifestyle and medication is highly effective.
Hypertension, or high blood pressure, affects nearly half of adults in the United States, with an estimated 11 million individuals unaware of their condition. This silent threat is a leading cause of preventable death, escalating the risk of heart disease, kidney disease, and stroke.
When left unchecked, high blood pressure causes arteries to thicken and stiffen, impairing blood flow and increasing the risk of emergencies like stroke. It can also lead to atherosclerosis, where plaque buildup further narrows arteries, potentially causing heart attacks. The heart itself can enlarge and thicken, progressing to heart failure.
Damage extends to the brain, significantly raising stroke risk, and may contribute to cognitive decline and dementia. Eyesight can be affected through hypertensive retinopathy, potentially causing blurred vision or blindness. Sexual health and kidney function are also compromised, as impaired blood flow and increased filtering stress the kidneys.
Peripheral artery disease can develop, reducing blood flow to the legs and causing walking difficulties. Despite these risks, managing hypertension is achievable. Heart-healthy lifestyle changes and available medications are highly effective in controlling blood pressure and mitigating its widespread impact.
