Some with high blood pressure report headaches (particularly at the back of the head and in the morning), as well as lightheadedness, vertigo, tinnitus (buzzing or hissing in the ears), altered vision or fainting episodes.[20] These symptoms, however, might be related to associated anxiety rather than the high blood pressure itself.[21] On physical examination, hypertension may be associated with the presence of changes in the optic fundus seen by ophthalmoscopy.[22] The severity of the changes typical of hypertensive retinopathy is graded from IIV; grades I and II may be difficult to differentiate.[22] The severity of the retinopathy correlates roughly with the duration or the severity of the hypertension.[20] Hypertension with certain specific additional signs and symptoms may suggest secondary hypertension, i.e. hypertension due to an identifiable cause Continue reading

10 Causes of Hypertension – A Diet High In Salt Content

Posted: April 10, 2018 at 2:40 am

Hypertension (high blood pressure) is a chronic medical condition that affects one in three adults in the US, as per the Centers for Disease Control and Prevention (CDC). Also called as the silent killer, it is a condition in which the blood pressure in the arteries is abnormally elevated.In most of the cases, the condition takes years to develop and people do not notice any symptoms initially. Most people find out about hypertension only when they suffer a heart attack or get a medical check-up done.Clyde Yancy, MD, chief of cardiology in Chicago, Illinois says that hypertension is simply unavoidable as a person ages.
