Loss of Energy
A loss of energy refers to a significant change in the amount of a person’s energy level from what they normally feel. Most people experience small changes in their energy level over the course of a day or the week; this does not refer to those normal fluctuations.
A person may say they feel fatigued with little or no physical exertion. Even the smallest tasks may seem to require substantial effort in someone who has suffered from a loss of energy. A person’s ability to complete tasks — such as at home or work — in a timely or efficient manner may also be a sign of loss of energy.
For example, a person may complain that washing and dress in the morning are exhausting, and take twice as long as usual. This kind of behavior would have to be experienced time and time again, not just once or twice, for it to be considered significant.
A loss of energy is a symptom of many mental health issues, including depression.
