what lowers hemoglobin

Several factors can lower hemoglobin levels, including:

• Nutritional Deficiencies: Lack of iron, vitamin B12, or folate can lead to anemia, which reduces hemoglobin.
• Chronic Diseases: Conditions like kidney disease, cancer, or chronic inflammation can affect hemoglobin production.
• Blood Loss: Heavy menstrual periods, gastrointestinal bleeding, or trauma can lower hemoglobin.
• Hemolysis: Destruction of red blood cells, often due to autoimmune disorders or infections.
• Medications: Certain drugs, such as chemotherapy or antiretroviral medications, can reduce hemoglobin.

If you suspect low hemoglobin, consult a healthcare provider for proper diagnosis and treatment.
