Which of the following is a symptom of anemia?

• A. Swelling
• B. Fatigue
• C. Fever
• D. Chills

Answer: (B)

Fatigue is a key symptom of anemia and arises due to the decreased blood capacity to carry oxygen to the body's tissues. When a person has anemia, their red blood cell count or hemoglobin levels are lower than normal. This deficiency leads to reduced oxygen delivery to muscles and organs, resulting in feelings of tiredness and weakness. Individuals with anemia may also experience decreased physical endurance and performance due to this lack of oxygen availability, making fatigue a prominent and common symptom associated with the condition. Other symptoms of anemia might include pallor, shortness of breath, and dizziness, but fatigue is often the most noticeable and consistent complaint among those affected.
