What is anemia?

Intermountain Registered Dietitians
Nutrition & Dietetics Specialist
Anemia is a condition in which your blood does not have enough red blood cells. Red blood cells carry oxygen to your body organs to help them use energy. If you don’t have enough red blood cells, your organs may not work as well as they should. This may make you look pale and feel tired, or you may not have any noticeable symptoms right away.
Dr. Michael T. Murray, ND
Naturopathic Medicine Specialist
Anemia is a condition in which the blood is deficient in red blood cells or the hemoglobin (iron-containing) portion of red blood cells. As noted, the primary function of the red blood cells (RBCs) is to transport oxygen from the lungs to the tissues of the body in exchange for carbon dioxide. The symptoms of anemia, such as extreme fatigue, reflect a lack of oxygen being delivered to tissues and a buildup of carbon dioxide.

Anemia is a condition in which the number of red blood cells is below normal. Anemia is the most common blood disorder. There are several types of anemia, all of which have a variety of underlying causes.

Some of the symptoms of anemia include:

  • Difficulty breathing
  • Loss of energy
  • Headaches
  • Feeling cold
  • Dizziness

This answer is based on source information from National Cancer Institute.

Anemia is a condition in which the number of red blood cells, the amount of hemoglobin (a part of the red blood cell), or the total volume of blood is less than normal, resulting in less oxygen being carried to the body's cells. Anemia can be caused by chronic kidney disease, low iron or folate levels, or bleeding problems. Anemia causes a feeling of extreme fatigue.

Anemia is a lack of iron or a deficiency of oxygen carrying capacity in red blood cells. Iron deficient anemia is a result of inadequate supply of dietary iron. It can also be a result of blood loss, usually during heavy menstruation.
