Introduction
Typical symptoms of moderate anemia include pallor of the skin and mucous membranes, general weakness and easy fatigue, shortness of breath and palpitations, dizziness, headache, difficulty concentrating, decreased appetite, and indigestion. If one or more of these symptoms occur, it is recommended to promptly visit a正规 hospital for a complete blood count (CBC) test to confirm the diagnosis. Insufficient hemoglobin leads to reduced oxygen-carrying capacity of the blood, resulting in pallor of the face, lips, and nail beds.

Moderate anemia typically presents with symptoms such as pale skin and mucous membranes, general weakness and fatigue, shortness of breath and palpitations, dizziness, headaches, difficulty concentrating, reduced appetite, and indigestion. If one or more of these symptoms occur, it is recommended to promptly visit a正规 hospital for a complete blood count (CBC) test to confirm the diagnosis.

1. Pale skin and mucous membranes: Insufficient hemoglobin reduces the blood's oxygen-carrying capacity, leading to decreased blood and oxygen supply to mucosal areas such as the face, lips, and nail beds, resulting in pallor. The paleness may worsen after physical activity.

2. General weakness and easy fatigability: Inadequate oxygen delivery to tissues and organs impairs energy production. Individuals may feel tired even after mild exertion, and rest often fails to provide rapid relief, affecting daily work and life.

3. Shortness of breath and palpitations: To compensate for low oxygen levels, the heart must pump faster. This can cause breathlessness and a rapid, pounding heartbeat even during light activity; in severe cases, symptoms may occur even at rest.

4. Dizziness, headaches, and poor concentration: Reduced oxygen supply to the brain affects neurological function, leading to dizziness and headaches, as well as impaired focus and memory, which can negatively impact learning and cognitive performance.

5. Loss of appetite and indigestion: Poor blood and oxygen supply to the gastrointestinal tract reduces digestive juice secretion and slows intestinal motility. This manifests as decreased appetite, bloating, poor digestion and absorption after meals, and may be accompanied by nausea or other discomforts.

In daily life, it is important to ensure adequate sleep and avoid excessive fatigue, maintain a balanced diet rich in high-quality protein and iron, engage in moderate exercise to improve physical fitness, and maintain a positive mental state to support recovery.
