Symptoms of anemia are caused by a low blood count, which means that the body is not receiving enough oxygen. This affects the ability of the body to carry oxygen to the brain, which causes fatigue and weakening. It can also affect the heart and blood circulation, causing pain and discomfort in the hands, legs, and feet.
Anemia is a common condition that affects more than three million Americans each year. It is caused by a lack of hemoglobin, a protein that carries oxygen throughout the body. When the amount of hemoglobin in the blood is low, the blood becomes less red and less oxygenated.
It is important to know the signs of anemia because it may indicate a serious medical problem. The symptoms can vary by type and severity of anemia, so it is best to discuss them with your doctor if you feel like you may have anemia.
Signs of anemia include fatigue, weak muscles, shortness of breath, and cold hands and feet. It is also possible to feel lightheaded or have difficulty concentrating.
Depending on the cause of the anemia, further blood testing may be required to look for damage to the heart, kidneys, lungs, or other organs. A doctor may prescribe an iron supplement or change your diet.
In addition to anemia, the symptoms of other medical conditions may also lead to decreased oxygen levels in the blood. For example, low levels of vitamin B12 may lead to anemia.
