What does it mean if you are always tired?

If you are feeling tired there is always a reason. Your body is trying to communicate that something is wrong or needed. Exhaustion can be manifested as a symptom from mental disorders such as depression or anxiety. It may also be from a lack of protein in the diet, anemia or lack of iron, low blood sugar levels, or a deficiency of vitamins or minerals. If this is a persistent problem, it is best to contact your family doctor.
