Use a home blood pressure monitor or get it checked at a clinic or pharmacy
A reading of 130/80 mmHg or higher may indicate high blood pressure
A reading of 140/90 mmHg or higher is high for many adults
Repeated high readings on different days are more important than one reading
High blood pressure often has no symptoms
Possible symptoms can include headaches, dizziness, blurred vision, chest pain, shortness of breath, or nosebleeds
Severe symptoms or very high readings need urgent medical attention
Confirm any high reading with a healthcare professional
