D52.9

Clinical Causes: Inadequate dietary intake of folate-rich foods such as leafy greens, fruits, and fortified grains Malabsorption syndromes like celiac disease or inflammatory bowel disease Increased demands for folate during pregnancy or rapid growth periods in adolescence Alcoholism, which interferes with proper folate absorption and utilization Certain medications, including anticonvulsants and methotrexate, that inhibit folate metabolism Chronic kidney disease affecting folate processing

Key Symptoms: Weakness and fatigue Pale skin Shortness of breath Dizziness or lightheadedness Sore or swollen tongue Poor appetite and weight loss Irritability or difficulty concentrating

Diagnosis Path: Diagnosis typically involves blood tests such as a complete blood count (CBC) to detect anemia, and specific measurements of serum folate levels. Additional tests might include homocysteine and methylmalonic acid levels, which can help determine the underlying cause of the anemia. The healthcare provider will also review medical history and dietary habits to pinpoint potential causes.

Treatment Protocols: Treatment focuses on replenishing folate levels, usually through dietary changes and supplementation. Patients may be advised to increase intake of folate-rich foods like leafy greens, citrus fruits, and beans. Folic acid supplements are often prescribed to restore normal folate levels. Managing underlying conditions, such as malabsorption or medication adjustments, is also crucial for effective treatment. In cases of severe anemia, additional supportive therapies such as blood transfusions might be considered.
