In some cases, it can also cause fainting. Orthostatic hypotension can be caused by a variety of factors, including dehydration, certain medications, and underlying medical conditions such as heart disease or diabetes. If you are experiencing these symptoms, it is important to see a doctor to rule out any underlying medical conditions and to discuss treatment options.
