High blood pressure often develops gradually and may not cause noticeable symptoms. Because of this, many people may have high blood pressure without realizing it. Regular blood pressure checks are important for identifying the condition.

Common Symptoms

Most people with high blood pressure do not experience symptoms. When symptoms occur, they may include:

• headaches
• dizziness
• shortness of breath
• vision changes 

Possible Causes

High blood pressure can develop from a combination of lifestyle, health and genetic factors. Common contributing factors include excess salt intake, being overweight, lack of physical activity, smoking, stress and certain medical conditions. Age and family history can also increase the risk of developing high blood pressure.
