The symptoms of exhaustion, sometimes also referred to as fatigue or chronic fatigue syndrome, include mental and physical exhaustion that remains constant, regardless of how much sleep a person gets. Symptoms can vary from person to person, but they often wax and wane, affecting all aspects of normal activity, according to the United Kingdom's National Health Service. Other symptoms include joint pain, sore throat, diarrhea and intolerance to light.
The National Health Service lists less common symptoms as excess sweating, dizziness and balance problems. The Mayo Clinic explains that in some cases, chronic fatigue can be a sign of an underlying medical condition. It is always advisable to seek advice from a health professional if exhaustion is long-lasting and interfering with normal everyday activities.
Many people who suffer from chronic exhaustion find the fatigue overwhelming. In some instances the tiredness is so severe and long-lasting that they find themselves unable to leave their house, says the National Health Service. For some people, physical activity makes the symptoms worse, although the effect can be delayed from a few hours to days afterward. For instance, participating in a sport on one day may result in complete exhaustion and limited functionality on the next.
