Tired? No energy? Need to take a nap?
I'm so tired. I just don't have any energy. I really need a nap. If these are words you find yourself thinking or muttering every day, you may be experiencing fatigue.
Everyone experiences it occasionally. It's the body's way of signaling its need for rest and sleep. But when fatigue becomes a persistent feeling of exhaustion that goes beyond normal sleepiness, it is usually a sign that something more serious may be happening.
Physically, fatigue is characterized by a profound lack of energy, feelings of muscle weakness, and slowed movements or central nervous system reactions. Fatigue can also trigger serious mental exhaustion. Persistent fatigue can cause a lack of mental clarity (or "fuzziness"), difficulty concentrating, and in some cases, memory loss.
Fatigue may be the result of one or more environmental causes such as inadequate rest, improper diet, work and home stressors, or poor physical conditioning. It may also be a symptom of a chronic medical condition or disease process in the body. Heart disease, low blood pressure, diabetes, end-stage renal disease, iron-deficiency anemia, narcolepsy, and cancer can cause long-term, ongoing fatigue symptoms. Acute illnesses such as viral and bacterial infections can also trigger temporary feelings of extreme exhaustion. In addition, mental disorders such as depression can also cause fatigue.
But so can low blood sugar, insufficient iron and other nutrients, or even overworked adrenalins. You may have dismissed your shifts of energy and general tiredness as just part of life. I'm busy so I'm overly exhausted.
It doesn't have to be so! If you're tired of being tired, I urge you to get help because fatigue can be treated.
