What causes the symptoms of anemia?

Anemia is a syndrome characterized by a reduction in peripheral blood red cell volume below the lower limit of the normal range, leading to tissue hypoxia. There are many causes, including acute and chronic blood loss, malnutrition, and deficiency of hematopoietic substances. The main symptoms include dizziness, headache, lethargy, and difficulty concentrating. Almost every system in the body may exhibit related symptoms. It is recommended to visit a hospital for a complete blood count (CBC) to check for anemia. If anemia is detected, further evaluation to identify the underlying cause and appropriate treatment is advised. Maintain a balanced diet, exercise regularly, and improve overall physical health.
