From the Guidelines
Anemia symptoms include fatigue, weakness, pale skin, shortness of breath, dizziness, headaches, cold hands and feet, chest pain, and irregular heartbeat, and the most effective treatment approach depends on the underlying cause and type of anemia, with a focus on addressing the root cause to improve morbidity, mortality, and quality of life. When considering treatment options, it is essential to prioritize the most recent and highest quality evidence, which suggests that iron deficiency anemia can be effectively treated with oral iron supplements, such as ferrous sulfate (325 mg three times daily), ferrous gluconate (300 mg twice daily), or ferrous fumarate (200 mg twice daily), typically taken for 3-6 months to replenish iron stores 1. For patients with chronic kidney disease (CKD), the KDIGO guideline recommends a trial of intravenous iron or a 1-3 month trial of oral iron therapy if the patient is not on iron or erythropoietin-stimulating agent (ESA) therapy 1. In addition to iron supplementation, vitamin B12 deficiency requires either oral supplements (1000-2000 mcg daily) or monthly injections (1000 mcg), while folate deficiency is addressed with daily folic acid supplements (400-1000 mcg). Severe anemia may require blood transfusions, and underlying conditions like CKD might need ESA therapy, although the use of ESA in patients with mild to moderate anemia and congestive heart failure or coronary heart disease is not recommended due to the potential risks 1. Some key points to consider when treating anemia include:
- Proper diagnosis through blood tests is essential before starting treatment
- Dietary changes, such as incorporating iron-rich foods, vitamin C, and B12 sources, can help alleviate anemia symptoms
- The treatment approach should be individualized based on the patient's specific needs and underlying conditions
- Regular monitoring of the patient's response to treatment is crucial to adjust the treatment plan as needed.

From the Research
Anemia Symptoms
- Fatigue, weakness, and shortness of breath are common symptoms of anemia 2, 3, 4, 5
- Patients may also experience palpitations, headache, and lethargy due to reduced tissue oxygenation 3
- In older adults, anemia may be asymptomatic or discovered incidentally on laboratory testing, but can also present with symptoms related to associated conditions 4
- Iron deficiency anemia can cause skin or conjunctival pallor, excessive sleepiness, learning disabilities, and diminished attention span in children 5
- Adults with iron deficiency anemia may experience shortness of breath, decrease in exercise tolerance, palpitations, and tachycardia 5
- Pernicious anemia, caused by vitamin B12 deficiency, can present with fatigue, pale appearance, tingling sensation, depression, and alterations to vision and smell 6
Treatment Options
- Treatment is directed at the underlying cause of anemia 4
- Symptomatic patients with serum hemoglobin levels of 8 g per dL or less may require blood transfusion 4
- Patients with suspected iron deficiency anemia should be given a trial of oral iron replacement, with lower-dose formulations being as effective and having a lower risk of adverse effects 4
- Parenteral iron infusion is reserved for patients who have not responded to or cannot tolerate oral iron therapy 4
- Intramuscular vitamin B12 injections are the most effective treatment for pernicious anemia 6
