Your lifestyle can have a major impact on your blood pressure. Make sure you've changed lifestyle factors that can contribute to high blood pressure, such as smoking, being overweight, drinking too much alcohol, not exercising enough or eating an unhealthy diet. Caffeine and even excessive may keep your blood pressure elevated.
Other health conditions
Certain underlying medical conditions, such as sleep apnea or kidney disease, can cause or worsen high blood pressure. When other conditions are to blame for your high blood pressure, you have secondary hypertension. In this case, you can generally get your high blood pressure under control by treating the underlying condition.
