Anemia Symptoms

Because a low red blood cell count decreases oxygen delivery to every tissue in the body, anemia may cause many signs and symptoms. It can also make almost any other underlying medical condition worse. If anemia is mild, it may not cause any symptoms. If anemia is slowly ongoing (chronic), the body may adapt and compensate for the change; in this case there may not be any symptoms until the anemia becomes more severe.

Symptoms of anemia may include the following:

• Fatigue
  
  
• weakness
  
  
• shortness of breath
  
  
• lightheadedness
  
  
• palpitations (feeling of the heart racing or beating irregularly)
  
  
• looking pale

Symptoms of severe anemia may include:

• chest pain, angina, or heart attack
  
  
• dizziness
  
  
• fainting or passing out
  
  
• rapid heart rate

Some of the signs that may indicate anemia in an individual may include:

• Change in stool color, including black and tarry stools (sticky and foul smelling), maroon-colored, or visibly bloody stools if the anemia is due to blood loss through the gastrointestinal tract.
  
  
• rapid heart rate
  
  
• low blood pressure
  
  
• rapid breathing
  
  
• pale or cold skin
  
  
• yellow skin called jaundice if anemia is due to red blood cell breakdown
  
  
• heart murmur
  
  
• enlargement of the spleen with certain causes of anemia
