Which of the following is a common clinical symptom that indicates anemia?

Fatigue and shortness of breath are hallmark symptoms of anemia due to the reduced capacity of the blood to carry oxygen to the tissues. Anemia occurs when there is a deficiency in the number of red blood cells or hemoglobin, leading to inadequate oxygen delivery throughout the body. As a result, individuals often experience feelings of extreme tiredness (fatigue) during routine activities. Similarly, due to the body’s compensatory mechanisms to increase oxygen supply, patients may also experience shortness of breath, particularly during exertion. This combination of symptoms is frequently recognized in clinical practice as a strong indicator of anemia.

On the other hand, pain in the chest might suggest a different condition, as it is typically associated with cardiac issues rather than anemia alone. Excessive thirst could be related to several other conditions, including dehydration or diabetes, and is not specific to anemia. Swelling of the limbs may indicate issues such as fluid retention or edema, which are not directly related to anemia.
