Low hemoglobin is commonly associated with which symptom?

• A. Weight gain
• B. Increased energy
• C. Fatigue with activity
• D. Shortness of breath at rest

Answer: (C)

Low hemoglobin reduces the blood’s oxygen-carrying capacity, so tissues don’t get enough oxygen, especially when you’re active. During exercise, oxygen demand goes up, but delivery remains limited, causing quicker fatigue and reduced exercise tolerance. That fatigue with activity is the most typical symptom of low hemoglobin. Weight gain isn’t associated with low hemoglobin, and while shortness of breath can occur with anemia, it’s more common during exertion rather than at rest unless the anemia is severe.
