Orthostatic hypotension is an over the top fall in BP when an upright position is expected. The agreement definition is a drop of > 20 mm Hg systolic, 10 mm Hg diastolic, or both. Side effects of faintness, unsteadiness, tipsiness, perplexity, or obscured vision happen inside of seconds to a couple of minutes of standing and resolve quickly on resting. A few patients experience falls, syncope (see Syncope), or even summed up seizures. Exercise or a substantial supper may worsen indications. Orthostatic hypotension is an indication of strange BP regulation because of different conditions, not a particular issue.Patients requiring prolonged bed rest should sit up each day and exercise in bed when possible. Patients should rise slowly from a recumbent or sitting position, consume adequate fluids, limit or avoid alcohol, and exercise regularly when feasible. Regular modest-intensity exercise promotes overall vascular tone and reduces venous pooling. Elderly patients should avoid prolonged standing. Sleeping with the head of the bed raised may relieve symptoms by promoting Na retention and reducing nocturnal diuresis.
Prospective experimental studies assessing nonpharmacologic interventions for management of orthostatic drop in blood pressure in various patient populations were included. All studies identified through the literature search were reviewed independently in duplicate. Of the 644 studies, 25 met the selection criteria.
