The way in which blood pressure readings are taken for children and teens means that readings that are considered by doctors to be high in teens can be lesser than the blood pressure readings that doctors consider above the accepted limits in adults. One of the most dangerous aspects related with hypertension is that almost half of the people having this condition is unaware about it. Therefore, it is highly advisable that people above 18 undergo regular check ups for hypertension.
Usually, the cause of hypertension remains unknown and this type of high blood pressure is termed as primary or essential hypertension. If the cause behind high blood pressure gets diagnosed successfully, it is termed as secondary hypertension. The usual causes of secondary hypertension include hormonal disorders, kidney problems, aorta abnormalities, or a shrinking of specific smaller arteries.
