Vertigo on waking up - Definition


Definition


Vertigo is the unpleasant feeling of loss of balance, feeling faint or the impression that the world is turning around you. When experienced upon waking up, this feeling can indicate a condition called orthostatic, or postural hypotension. This condition typically manifests on moving from lying down to an upright position, when blood flows into the legs by the force of gravity, and a normally functioning body is able to adapt in order to avoid a drop in blood pressure; however it is unable to do so when affected by orthostatic hypotension. This drop in blood pressure is the cause behind vertigo or dizziness, which can even lead to fainting with a loss of consciousness and fall. Orthostatic hypotension mostly affects the elderly. Its diagnosis is confirmed by taking blood pressure measurements when lying down, which are then monitored at several different times while getting up and standing upright. If this condition is diagnosed, treatment should be adapted, notably treatments for hypertension.
