How to Reduce Lightheadedness and Dizziness When Standing Up (Orthostatic Hypotension)
Orthostatic hypotension, also known as postural hypotension, is characterized by a drop in blood pressure when standing up. As there is reduced blood flow to the brain, lightheadedness (a feeling of faintness or dizziness) commonly occurs, as can other symptoms such as blurred vision, nausea, headache, and brain fog. Shortness of breath, shaking, and rapid heartbeat can also occur.
When this occurs within 15 seconds of standing, it is called "initial" orthostatic hypotension, and it often occurs in people considered otherwise healthy. Note that there are other forms of orthostatic hyportension, including "classic" (within 30 seconds to 3 minutes of standing) and "delayed" (after 3 minutes of standing) that can occur due to dysfunction of the nervous system.
Researchers have shown that symptoms of initial orthostatic hypotension can be significantly reduced with simple movements performed right before, or immediately after, standing. For details, sign in.
Be aware that vitamin D deficiency has been associated with a greater risk of orthostatic hypotension, although it is not clear that supplementing with vitamin D reduces symptoms. In addition, a preliminary report suggested that CoQ10 helped maintain blood pressure in older people with orthostatic hyportension.
