Diabetes
One of the complications of diabetes is damage to the nerves in the body, including those in the autonomic nervous system. In those people with diabetes who have autonomic dysfunction, orthostatic hypotension can occur. The blood vessels are unable to adjust to quick positional changes.
Micturition Syncope
One of the most common causes of syncope, (passing out or fainting), occurs when a person strains to urinate or have a bowel movement. This stimulates the vagus nerve, increasing acetylcholine in the body and dilating blood vessels, causing blood pressure to fall and decreasing blood supply to the brain. Though it is frightening and may result in a fall, micturition syncope is self-limiting, resolves quickly, and may need little treatment.
