High Blood Pressure and Dizziness
Dizziness is one of the most common symptoms that will prompt
an individual to visit a doctor. The term dizzy (or dizziness) can be difficult to define because
it can mean different things to different people. Does feeling dizzy refer to lightheadedness, the
feeling of weakness and almost passing out, or does it refer to vertigo (in which the room or the
person seems to spin)? Dizziness is one of the symptoms of chronic high blood pressure is
dizziness, in addition to headache, blurred vision and fatigue.
Dizziness is also a side effect of some high blood pressure medications
Increased blood pressure does
not appear to cause dizziness – but it is a side effect of some high blood pressure medications,
especially alpha blockers and alpha-beta blockers. If you get dizzy while taking any
medication, talk to your doctor about other drugs that might work for you with fewer side
effects. Additionally, much research on dizziness and blood pressure indicates that low blood
pressure is generally the culprit.
When the blood pressure drops,
dizziness is a common side effect. A person who gets light-headed when standing up too quickly
is experiencing orthostatic hypotension – dizziness that occurs when systolic blood pressure
(the top number) drops more than 20 mm Hg or diastolic (the bottom number) drops more than 10 mm
Hg. But age – not high blood pressure – is the most common risk factor for this
condition.The important thing to take note of is what your blood pressure readings are when you
experience the dizziness whether low or elevated.
Sudden dizziness, loss of
balance or coordination, or trouble walking are all warning signs of a stroke. So you must
contact your doctor to resolve this situation.
