ANS Diseases, also known as Autonomic Nervous System diseases, refer to a group of medical conditions that affect one's autonomic nervous system. This system plays a crucial role in regulating subconscious bodily functions, such as heart rate, respiration, blood pressure, digestion, and temperature control. Synonyms commonly used to designate ANS Diseases include Autonomic Dysfunction, Dysautonomia, Autonomic Neuropathy, and Autonomic Disorders. These terms are interchangeable and describe conditions where the autonomic nervous system does not function properly, leading to a wide range of symptoms like dizziness, fainting, blurred vision, abnormal sweating, digestive problems, and irregular heartbeats. Awareness of these synonyms helps individuals, caregivers, and healthcare practitioners to better understand and communicate about ANS Diseases.
