What are the Health Implications of Abnormal Hemoglobin Levels?
Low hemoglobin levels (anemia) can lead to symptoms such as fatigue, weakness, shortness of breath, and dizziness. Causes of anemia include iron deficiency, vitamin B12 deficiency, chronic diseases, and genetic conditions like sickle cell anemia. High hemoglobin levels (polycythemia) can cause complications such as blood clots, heart attacks, and strokes, and may result from conditions like chronic lung disease or living at high altitudes.
