About this condition
Hypertension, or high blood pressure, occurs when blood pressure remains elevated. People often feel well despite high readings, so measuring blood pressure is important even without symptoms. A single high reading does not establish a diagnosis.
Why repeated readings matter
Blood pressure changes throughout the day. Exercise, anxiety, caffeine, arm position and cuff size can affect readings. Clinicians therefore consider repeated measurements taken in a healthcare setting and, when appropriate, at home rather than relying on one result.
Preparing for your appointment
Bring a record of home readings with dates and times, a medication list and any previous test results. Tell the clinician about kidney disease, diabetes, smoking, cardiovascular disease in the family and any treatment side effects.
The importance of ongoing follow-up
Uncontrolled hypertension can increase the risk of complications affecting the heart, brain and kidneys even when you feel well. Follow-up helps assess individual risk, agree on a realistic management plan and review progress over time.
Signs and symptoms
High blood pressure frequently causes no symptoms. Some people experience headaches, dizziness, ringing in the ears, palpitations or chest discomfort. These symptoms are not specific to hypertension and cannot confirm it.
Headache and dizziness can occur for many reasons. Use measured readings rather than symptoms alone to assess blood pressure.
Diagnosis and tests
The clinician reviews repeated blood pressure readings, associated conditions and risk factors. Depending on the findings, home monitoring, 24-hour ambulatory blood pressure monitoring, blood tests, an ECG or other investigations may be recommended.
A validated automatic upper-arm monitor is generally preferable for home readings. Your clinician can explain how often to measure and whether ambulatory monitoring is needed.
Care and treatment approaches
Management may include lifestyle changes and prescribed medication where indicated. Do not start, stop or adjust blood pressure medicine without medical advice.
Reducing excess salt, staying active within your abilities, stopping smoking and addressing other risk factors may help. Blood pressure targets and medicines are chosen individually.
When to seek urgent care
Severe chest pain, sudden weakness on one side of the body, speech difficulties, marked breathlessness or loss of consciousness require emergency medical help: call 103 in Ukraine.
Frequently asked questions
Can high blood pressure occur without a headache?
Yes. Hypertension often causes no obvious symptoms, which is why taking blood pressure readings matters.
Is one high blood pressure reading enough for a diagnosis?
No. The circumstances and repeated readings must be assessed with your overall condition. Emergency symptoms require immediate care.
