Monitoring your blood pressure on-site can:

• Help with early diagnosis. Self-monitoring can help your doctor diagnose high blood pressure earlier than if you have only occasional blood pressure readings in a medical office. Home monitoring is especially important if you have elevated blood pressure or another condition that could contribute to high blood pressure, such as diabetes or kidney problems.
• Help track your treatment. The only way to know whether your lifestyle changes or medications are working is to check your blood pressure regularly. Monitoring blood pressure changes at home can help you and your doctor make decisions about your treatment, such as adjusting dosages or changing medications.
• Encourage better control. Self-monitoring can give you a stronger sense of responsibility for your health. You may feel even more motivated to control your blood pressure with an improved diet, physical activity and proper medication use.
• Cut your health care costs. Self-monitoring might decrease your number of visits to your doctor or clinic.
• Check if your blood pressure differs outside the doctor’s office. Some people experience spikes in blood pressure due to anxiety associated with seeing a doctor (white coat hypertension). Other people have normal blood pressure at a clinic but elevated pressure elsewhere (masked hypertension). Monitoring blood pressure at home can help determine if you have true high blood pressure.

Not everyone can track blood pressure at home. If you have an irregular heartbeat, home blood pressure monitors might not give you an accurate reading.
