What Causes Low Hemoglobin Levels?

Low hemoglobin levels, known as anemia, can be caused by various factors including:

  • Nutritional Deficiencies: Lack of iron, vitamin B12, or folate in the diet can lead to anemia.

  • Chronic Diseases: Conditions like kidney disease, cancer, and rheumatoid arthritis can affect hemoglobin production.

  • Blood Loss: Heavy menstrual periods, gastrointestinal bleeding, or injuries can cause a significant drop in hemoglobin levels.

  • Bone Marrow Disorders: Diseases affecting the bone marrow, where blood cells are produced, can result in low hemoglobin levels.

  • Genetic Conditions: Disorders like sickle cell anemia and thalassemia affect hemoglobin production and function.
