Our bodies need iron for the production of red blood cells that carry hemoglobin throughout the body. Too few healthy red blood cells can result in anemia, a common blood disorder. Anemic individuals have an insufficient amount of hemoglobin to carry oxygen to the tissues throughout the body. The signs of anemia are generally understated and vague. When anemia is mild, there may not be any signs at all. However, when it comes on quickly or is more severe, it can cause many symptoms.
Without sufficient oxygenated blood, the body becomes fatigued. Typically, the first and most common symptom of anemia is a loss of energy. Fatigue associated with anemia is usually profound tiredness that affects one's overall quality of life. The person may experience an unusual drop in energy levels that persists throughout the day, hampering daily activities. This symptom will develop even if the individual is getting adequate, high-quality sleep.
