User:Mr. Ibrahem/Autonomic dysfunction

Autonomic dysfunction is a condition in which the autonomic nervous system (ANS) does not work properly. Symptoms may include lightheadedness with standing, dilated and poorly reactive pupils, rapid heart rate, alterations in sweating, erectile dysfunction, and urinary problems. Depending on the underlying cause symptoms may worsen over time or resolve.

Causes may include vasovagal syncope, diabetes, Parkinson's disease, postural orthostatic tachycardia syndrome, alcoholism, multiple system atrophy, Guillain-Barre syndrome, multiple sclerosis, amyloidosis, familial dysautonomia, hyperhidrosis, autonomic dysreflexia, complex regional pain syndrome, and certain medications. Diagnosis may be based on variation in blood pressure and heart rate between lying down and standing and tests of sweating.

Generally there is no specific cure. Treatment may involved addressing the underlying cause and measures to improve symptoms. Low blood pressure with standing may be improved with compression stockings and a high salt diet. If the bladder does not contract a urinary catheter may be required. Outcomes depend on the underlying cause. It occurs relatively commonly. The problem become more frequent with age.
