A primary symptom of anemia due to a decrease in red blood cells is easy fatigue and loss of energy. This occurs because red blood cells are responsible for transporting oxygen throughout the body. When there is a deficiency in red blood cells, the body's tissues and organs receive less oxygen, leading to feelings of tiredness and decreased energy levels. This is especially noticeable during physical activity, as the body struggles to meet its oxygen demands.

While other symptoms, such as pale skin, dizziness, and leg cramps, can also be associated with anemia, they are often secondary signs or may arise under specific conditions. Pale skin results from reduced blood flow or inadequate red blood cell levels, dizziness may occur due to insufficient oxygenation to the brain, and leg cramps can be related to muscle fatigue. However, the hallmark symptom that impacts daily activities and is often first noticed by individuals is the increased tendency to tire easily and the overall loss of energy.
