It is normal to feel a lack of energy, or to be tired or drowsy at times. This is called "lethargy," and it is usually transient. A person may even act sluggish, listless, or uninterested. When lethargy continues, it may be a sign of a more serious problem.
Depression is the most common cause of persistent lethargy. Other causes of lethargy include: - head injury
- use of drugs or alcohol
- infections
- diseases such as diabetes, leukaemia, lymphoma, glandular fever, and encephalitis
- high or low blood pressure
- poor nutrition, especially in babies and young children
- thyroid or adrenal gland disorders
In cases of serious injury, infection, or disease, lethargy can worsen into a daze, or even unconsciousness. Be sure the lethargic person can answer basic questions such as the day or date, where he or she is, and commonly known facts. If not, get immediate medical attention. Call 000 if the person loses consciousness. OTHER, NOT SO SERIOUS, SYMPTOMS OF LETHARGY MAY INCLUDE: - a tired feeling when waking in the morning.
- difficulty doing simple tasks
- difficulty concentrating
- multiple aches and pains
- appetite and bowel pattern changes and
- sleep disturbances
It is not good simply to treat lethargy with caffeine, drugs, or vitamins without a medical evaluation. If it continues, seek medical care. Article #6734 Copyright (c) 2002 McKesson. All Rights Reserved. |
