What are the symptoms of a low hematocrit?

As a hematologist, I specialize in the study and treatment of blood disorders, including conditions that affect the hematocrit level. Hematocrit is the percentage of the total blood volume that is made up of red blood cells (RBCs). A low hematocrit can be indicative of anemia, which has several potential causes and symptoms. Symptoms of a low hematocrit can include: 1. Fatigue: A lack of RBCs means less oxygen is being transported to the body's tissues, leading to tiredness. 2. Pale skin: Red blood cells contain hemoglobin, which gives skin its pink color. A decrease in RBCs can result in a paler complexion. 3. Shortness of breath: Due to the reduced oxygen-carrying capacity of the blood. 4. Dizziness or lightheadedness: Again, this is due to the body's tissues not receiving enough oxygen. 5. Headaches: Can be a result of the body's attempt to compensate for the lack of oxygen. 6. Cold intolerance: People with anemia may feel cold more easily because the body is not producing enough heat. 7. Heart palpitations: The heart may beat faster to try to compensate for the lower oxygen levels. 8. Swelling in the legs: This can occur if anemia is due to a chronic condition that affects the heart's ability to pump effectively. It's important to note that the severity of these symptoms can vary widely depending on the underlying cause and the individual's overall health.

Causes of low hematocrit, or anemia, include:Bleeding (ulcers, trauma, colon cancer, internal bleeding)Destruction of red blood cells (sickle cell anemia, enlarged spleen)Decreased production of red blood cells (bone marrow supression, cancer, drugs)Nutritional problems (low iron, B 12, folate and malnutrition)More items...
