Which symptom is most commonly associated with anemia due to decreased RBC production in chronic kidney disease?

• A. Fatigue and weakness
• B. Hyperactivity
• C. Polyphagia
• D. Nasal congestion

Answer: (A)

In anemia from chronic kidney disease, the kidneys don’t produce enough erythropoietin, which signals the bone marrow to make red blood cells. With less erythropoietin, RBC production drops, so there are fewer red cells to carry oxygen to tissues. That reduced oxygen delivery leads to tissue hypoxia, making activities feel more tiring and draining, which is why fatigue and weakness are the most common and noticeable symptoms. The other listed symptoms don’t fit this specific cause. Hyperactivity isn’t typical of CKD-related anemia, polyphagia points more to metabolic issues like diabetes, and nasal congestion isn’t related to anemia or reduced RBC production.
