Which of the following is a symptom of anemia?

• A. High energy and alertness
• B. Fatigue and pallor
• C. Excessive sweating and heat intolerance
• D. Increased appetite and weight gain

Answer: (B)

Fatigue and pallor are classic symptoms of anemia, which is a condition characterized by a deficiency of red blood cells or hemoglobin, leading to reduced oxygen delivery to tissues. As a result, individuals with anemia often experience increased fatigue and weakness because their bodies are not receiving enough oxygen to perform day-to-day activities. Pallor, or paleness of the skin, occurs because there is less red blood cell circulation, making it harder for the blood to provide that healthy color.

High energy and alertness, excessive sweating and heat intolerance, or increased appetite and weight gain do not align with the typical signs of anemia. Instead, they relate to other health conditions and do not reflect the oxygen deprivation and low energy levels associated with anemia. This further emphasizes why fatigue and pallor are specifically indicative of this condition.
