F45.3: Somatoform autonomic dysfunction

Somatoform autonomic dysfunction is a psychological disorder that primarily affects the body's autonomic nervous system, which controls various internal functions such as heart rate, digestion, respiratory rate, and blood pressure, to name a few. Instead of being caused by a physical ailment, the symptoms originate from mental or emotional distress. Patients with this condition often experience physical symptoms that mimic those of a physical disease affecting the autonomic nervous system, but medical examinations and tests do not detect any underlying physical cause. Common symptoms may include unexplained pain, fatigue, and problems with coordination and balance. The condition's progression varies greatly among individuals and it often coexists with other mental health conditions. It can significantly impact a person's quality of life as they may struggle with routine daily tasks due to the perceived physical ailments.
