Autonomic disease refers to a condition where the autonomic nervous system (ANS) is damaged, resulting in the inability to control involuntary bodily functions such as blood pressure, heart rate, and digestion. Therefore, antonyms for autonomic disease would denote the normal functioning of the ANS. Such antonyms could include "healthy," "normal," "balanced," "regulated," "controlled," "coordinated," or "functioning." These words convey the opposite of ANS disorders that can lead to a host of debilitating symptoms such as dizziness, fainting, digestive issues, and breathing problems. It is important to note that maintaining a healthy balance of the ANS is vital to overall wellbeing and a fulfilling life.
