Prevention of orthostatic hypotension is related to the cause. Making sure to get enough fluids can help prevent cases due to dehydration. Avoiding certain drugs can prevent cases from this cause. Avoiding prolonged bed rest can help prevent this cause. Many cases cannot be prevented.
If someone with orthostatic hypotension faints when he or she stands up, there is a potential for injury. Most long-term effects are related to the cause. For example, a spinal cord injury can leave someone with permanent numbness or paralysis. Cases due to dehydration or drugs are usually treatable and often have no long-term effects.
Orthostatic hypotension is not contagious, and poses no risk to others.
