Anemia is a lack of healthy red blood cells. A lack of these essential components can result in too little oxygen being delivered throughout the body, which can result in many health problems. When organs become depleted in this vital substance, they lose the ability to function in their full capacity.
One of the more common early warning signs of anemia is headaches that may range in severity from light pressure to a pounding that causes severe pain. People may also experience lightheadedness or dizziness, especially when sitting down or standing up quickly. In severe cases, this can lead to fainting spells. All of these symptoms occur due to the lack of oxygen reaching the brain. In most cases, when the iron count goes up, these symptoms lessen in both frequency and severity.
