What is a common symptom of anemia?

Chronic fatigue is a common symptom of anemia due to a decrease in the number of red blood cells or hemoglobin, which is essential for transporting oxygen throughout the body. When the body doesn’t receive enough oxygen, it can lead to feelings of tiredness and a lack of energy during physical and mental activities. This fatigue can be persistent and may interfere with daily tasks and overall quality of life.

The other options reflect conditions that are not associated with anemia. An increased appetite typically is not a symptom of anemia, as the body is often struggling to utilize energy effectively due to reduced oxygenation. Improved mental clarity is contrary to the cognitive effects seen in anemia, where individuals may experience brain fog or difficulty concentrating. Similarly, heightened energy levels are not characteristic of anemia; instead, individuals often feel lethargic and exhausted.
