Fatigue and weakness are symptoms of which condition?

• A. Anemia
• B. Fever
• C. Cough
• D. Rash

Answer: (A)

Anemia reduces the blood's oxygen-carrying capacity, so tissues don’t get enough oxygen. When red blood cells or hemoglobin are low, oxygen delivery to muscles and organs decreases, making you feel tired and weak. That’s why fatigue and weakness are classic signs of anemia. Fever, cough, and rash aren’t primarily tied to reduced oxygen transport. Fever comes from infection or inflammation, a cough points to respiratory irritation or infection, and a rash reflects skin or allergic reactions. They can accompany illness but don’t define anemia.
