Fatigue can be a normal and important response to physical exertion, emotional stress, boredom or lack of sleep. However, it can also be a sign of a more serious mental or physical condition. Dr. Edward Hill discusses fatigue in todays 60 Second Housecall.

Dr. Hill:

Fatigue is a feeling of weariness, tiredness or lack of energy. Fatigue can be a normal response to physical work, stress, poor nutrition or lack of sleep. But fatigue that is out of proportion to these stresses may be a sign of an underlying medical problem.

Fatigue is different from drowsiness. It is a lack of energy and motivation. Fatigue that is present when you first awaken may have a different cause than fatigue that worsens during the day or after minimal exertion.

Some common causes of fatigue include:

- Sleep disorders like sleep apnea

- Anemia or low blood counts

- Allergies to certain environmental triggers

- Under active or over active thyroid

- Untreated depression

- A side effect of prescription or over-the-counter medications

- Alcohol or drug abuse, and

- Undiagnosed diseases such as diabetes, infection, lupus or cancer

Some people suffer from chronic fatigue syndrome that as yet, has no specifically identified cause. See your physician for symptoms of persistent fatigue.
