What Are the Symptoms of Abnormal Hemoglobin Levels?

  • Symptoms of low hemoglobin levels (anemia) can include fatigue, weakness, shortness of breath, dizziness, pale skin, and irregular heartbeats.
  • Symptoms of high hemoglobin levels, which can be caused by conditions like polycythemia vera or living at high altitudes, may include headaches, dizziness, itching, and an increased risk of blood clots.
  • Both conditions require medical evaluation and management.
