G99.0: Autonomic neuropathy in endocrine and metabolic diseases

Autonomic neuropathy in endocrine and metabolic diseases refers to damage to the nerves that manage everyday bodily functions due to disorders that affect the body's endocrine, or hormone-producing, system and metabolic processes. These nerves play a crucial role in controlling functions such as heart rate, blood pressure, digestion, and body temperature regulation. Causes might include conditions like diabetes, thyroid disorders, or adrenal gland disorders. Symptoms may vary widely based on the nerves affected, but typically include dizziness or fainting, urinary problems, sexual difficulties, trouble regulating body temperature, digestive issues, and changes in blood pressure. Patients may experience gradual disease progression with increased symptom severity over time.
