Hypertension, or high blood pressure, is a common condition where the force of blood against the artery walls is persistently elevated. It is often asymptomatic in early stages and may only be detected through routine checks, yet it remains a major contributor to heart disease, stroke, and kidney damage. Typical signs may include headaches, visual disturbances, or dizziness, though many individuals remain unaware until complications arise.
There are many potential causes of hypertension, including genetic predisposition, lifestyle factors, kidney disease, and hormonal imbalances. Diagnosis involves repeated blood pressure measurements, assessment of cardiovascular risk, and investigations to identify any secondary causes. Understanding the underlying driver is essential to guide treatment and evaluate long-term risk.
Management focuses on lifestyle modification and medications to lower blood pressure and reduce cardiovascular risk. This may include dietary changes, increased physical activity, and pharmacologic therapy tailored to individual needs. Ongoing monitoring is important to ensure blood pressure targets are met and to adjust treatment over time. Specialist input can help clarify complex cases and support safe, effective care.
Identifying the cause of hypertension begins with repeated blood pressure measurements and a thorough clinical assessment, including blood and urine tests and evaluation for end-organ effects. It’s important to rule out white coat hypertension and consider secondary causes such as kidney disease, hormonal disorders, or medication effects. Clarifying the underlying cause helps guide treatment decisions and informs the intensity of long-term monitoring and cardiovascular risk reduction.
Treatment of hypertension involves a combination of lifestyle changes and medication, with a goal of maintaining blood pressure below 130/90 mmHg. Lifestyle strategies include reducing salt intake, regular physical activity, weight management, limiting alcohol, and stopping smoking. Medications are selected based on individual risk factors, comorbidities, and response to therapy, and often require combination treatment to achieve target. Regular monitoring helps assess effectiveness, manage side effects, and support long-term adherence.
Ongoing monitoring is essential in hypertension management, as blood pressure can fluctuate over time due to aging, lifestyle changes, medications, or emerging comorbidities. Regular review helps ensure that treatment remains appropriate and that blood pressure targets are maintained, reducing the long-term risk of cardiovascular events such as stroke, heart failure, and kidney disease.
