High blood pressure

Usually, no symptoms are present. Occasionally, you may experience a mild headache. If your headache is severe, or if you experience any of the symptoms below, you must be seen by a doctor right away. These may be a sign of dangerously high blood pressure (called malignant hypertension) or a complication from high blood pressure.

• tiredness
• confusion
• vision changes
• angina-like chest pain (crushing chest pain)
• heart failure
• blood in urine
• nosebleed
• irregular heartbeat
• ear noise or buzzing

Hypertension may be suspected when the blood pressure is high at any single measurement. It is confirmed through blood pressure measurements that are repeated over time. Blood pressure consistently elevated over 140 systolic or 90 diastolic is called hypertension. Your doctor will look for signs of complications to your heart, kidneys, eyes, and other organs in your body.

Systolic blood pressure consistently between 120 and 139 or diastolic blood pressure consistently between 80 and 89 is called pre-hypertension. Your doctor will recommend and encourage lifestyle changes including weight loss, exercise, and nutritional changes.

Tests for suspected causes and complications may be performed. These are guided by the symptoms presented, history, and results of examination.
