The patients often complain of getting exhausted too fast. This feeling can be better described as fatigue as it is not about simply getting overloaded and tired after a long working day. In the first case, the person is running out of energy; in the second case, the person wants to have a rest to recover. Dysautonomia may even end up in the inability to think or act any longer. It is important to make an attempt to exercise to get rid of this sign over time.
