How are you? Hypertension, a chronic medical condition in which the blood pressure in the arteries is elevated, can be classified as either primary (essential) or secondary. Majority of cases are termed primary hypertension, which refers to high BP for which no medical cause can be found while secondary hypertension are caused by other conditions that affect the kidneys, arteries, heart, or endocrine system. In your case, normal diagnostic results suggests you have primary or essential hypertension. Stress may be contributory as well as genetics. Low salt diet as well as regular exercise may help. Medications, taken as prescribed, also help in improving BP control and decrease the risk of associated health complications such as stroke. Regular blood pressure monitoring and regular follow-up are highly recommended. Take care and do keep us posted.
