Autoimmune Autonomic Ganglionpathy

 

 

Overview

Caused by the immune system’s attack on the autonomic nervous system, which regulates non-voluntary bodily functions such as heartbeat, AAG can either be classified as being associated with high levels of g-AchR antibodies (seropositive) or as having no detectable levels of the antibodies (seronegative).

Common Symptoms

Constipation, urinary retention, fainting, fixated and dilated pupils, dry mouth and eyes, absence of sweating, abdominal pain and vomiting, sexual dysfunction, and very low blood pressure upon standing (severe neurogenic orthostatic hypotension, also known as postural orthostatic tachycardia syndrome (POTS).

Risk Factors

AAG is most likely to occur between 50-70 years of age, and while it affects both sexes, it is more prevalent in females.
