Hello, Lisa, there are several causes for the loss of balance, the most common is not related to blood pressure levels and is known as benign paroxysmal positional
vertigo.
Benign paroxysmal positional vertigo is a horrible name, but it is not a serious illness. It occurs when some pebbles that we all have within our inner ears leave their usual place. Typically, they send signals to the brain about the position of the head relative to gravity. When they leave the place, they start to send wrong signals of position, coming into conflict with the coming of sight information, generating a loss of balance. And it is common that these stones leave the site after trips to high mountains after ship trips or even plane.
Both very
high blood pressure levels, as the very low can also cause loss of balance, but is much less common than benign paroxysmal positional vertigo. So it is not safe to take medications to lower blood pressure, such as diuretics, and it may even worsen the symptoms.
I suggest you look for a
ENT specialist to evaluate and treat possible benign paroxysmal positional vertigo and a cardiologist to determine if you have high blood pressure and need to take medications or can begin treatment only with changes in lifestyle.
Hope I have answered your question. If you have any further questions I will be happy to help you. Wish you good health.
