What is a common symptom of anemia related to chronic kidney disease?

1. Increased energy levels

2. Shortness of breath

3. Improved appetite

4. Enhanced concentration

The correct answer is: Shortness of breath

Shortness of breath is a common symptom of anemia related to chronic kidney disease due to the insufficient production of red blood cells. When kidneys are not functioning properly, they may produce less erythropoietin, a hormone essential for red blood cell production. As a result, the body may not have enough red blood cells to carry oxygen effectively, leading to reduced oxygen supply to tissues and organs. This lack of oxygen can cause fatigue and weakness, which can manifest as shortness of breath, especially during physical activity. The heart may also need to work harder to pump oxygenated blood throughout the body, contributing to feelings of dyspnea. Recognizing shortness of breath as a symptom allows for proper management of anemia and underlying renal issues, ensuring that patients receive appropriate treatments such as erythropoiesis-stimulating agents or iron supplementation. In contrast, increased energy levels, improved appetite, and enhanced concentration are typically not associated with anemia and chronic kidney disease. Adequate red blood cell levels usually support these functions, but when anemia is present, patients often experience fatigue, decreased appetite, and difficulty concentrating instead.
