| Video Discription | Orthostatic hypotension has two forms that result from two main causes. The neurogenic form is caused by problems with the autonomic nervous system, which controls involuntary body functions, including blood pressure. Normally when someone stands up, processes regulated by the autonomic nervous system make the heart beat faster and the blood vessels narrow, which increases blood pressure and blood flow in the body to compensate for gravity's effect on blood movement. Disorders that affect the autonomic nervous system can impair the adjustment of blood pressure, leading to orthostatic hypotension. These disorders often have a strong genetic component and may affect multiple members of a family. Neurogenic orthostatic hypotension often occurs along with nervous system disorders such as Parkinson disease, dementia with Lewy bodies, multiple system atrophy, pure autonomic failure, diabetes, Guillain-Barré syndrome, dopamine beta-hydroxylase deficiency, or infections that cause disturbances in nerve function (neuropathy). The non-neurogenic form of orthostatic hypotension is often caused by environmental or health factors that impair the body's mechanisms to stabilize blood pressure upon standing. These factors include heart disease, low blood volume (hypovolemia), alcohol use, or advanced age. Certain medications can also contribute to non-neurogenic orthostatic hypotension, such as antipsychotic or antidepressant drugs, drugs that treat high blood pressure by widening blood vessels (vasodilators), or drugs that help remove water and salt from the body (diuretics). The non-neurogenic form of orthostatic hypotension is more common than the neurogenic form, but in about 40 percent of people with orthostatic hypotension the underlying cause is unknown (idiopathic). |
