High Blood Pressure: Understanding the Risks When Diastolic Blood Pressure Exceeds 90
When a person's diastolic blood pressure consistently exceeds 90 mmHg, it can be classified as high blood pressure, especially if the systolic pressure is above 140 mmHg. This condition can significantly increase the risk of various health complications. Understanding these risks is essential for early intervention and prevention of severe health issues.Impact on the Kidneys
Chronic high blood pressure can damage the small blood vessels in the kidneys, leading to renal injury and glomerulosclerosis. This damage can progress to renal artery hardening and narrowing, impairing kidney function over time. If left untreated, this can eventually lead to chronic kidney disease or even kidney failure.
Cardiovascular Complications
One of the most significant concerns with elevated diastolic pressure is the effect on the heart. The coronary arteries may develop atherosclerosis, which is the buildup of plaque that narrows the arteries and restricts blood flow. This can lead to angina or, in more severe cases, a sudden blockage causing a heart attack. Maintaining healthy blood pressure levels is crucial for cardiovascular health.
Effects on Vision and Eye Health
Eye-related complications are also a concern when blood pressure remains high. Elevated diastolic pressure can cause hardening of the arteries in the retina, leading to retinopathy. This condition may result in vision impairment or even vision loss if not addressed promptly. Regular eye exams are recommended for individuals with hypertension.
Risks to Brain Health
Long-term high diastolic blood pressure can lead to cerebral atherosclerosis, where plaque buildup in the brain's arteries causes narrowing or blockages. This increases the risk of ischemic events or strokes. Ensuring proper blood pressure management is vital for maintaining cognitive function and preventing life-threatening conditions such as cerebral infarction.
