Anemia in Older Adults.

Area of Science:

• Geriatrics
• Hematology
• Internal Medicine

Background:

• Anemia is common in older adults, linked to higher morbidity and mortality.
• Diagnostic criteria for anemia vary, and it's often asymptomatic.
• Symptoms can include weakness, fatigue, and shortness of breath due to reduced oxygen capacity.

Purpose of the Study:

• To outline the diagnostic approach to anemia in older adults.
• To identify common causes and appropriate investigations.
• To guide treatment strategies for anemia in this population.

Main Methods:

• Comprehensive history and physical examination.
• Assessment of risk factors and mean corpuscular volume (MCV).
• Serum ferritin testing for normocytic/microcytic anemia; endoscopy for suspected iron deficiency; evaluation for B12/folate deficiency, myelodysplastic syndrome, or malignancy in macrocytic anemia.

Main Results:

• Low serum ferritin suggests iron deficiency anemia, warranting gastrointestinal evaluation.
• Elevated ferritin or macrocytic anemia indicates potential B12/folate deficiency, myelodysplastic syndrome, or malignancy.
• Treatment focuses on the underlying cause, with oral iron for iron deficiency and transfusions for severe symptomatic anemia.

Conclusions:

• Anemia in older adults necessitates a thorough diagnostic workup.
• Identifying and treating the specific cause of anemia is crucial for improving patient outcomes.
• Timely intervention, including iron replacement or addressing other etiologies, can normalize hemoglobin levels.
