Dr. Zhang Heyang
Symptoms of anemia include pale complexion, general weakness, sleep disturbances at night, insomnia with frequent dreams, and night sweats. Some anemic patients may experience nail abnormalities, hair loss, and yellowing of the skin or hair. For iron-deficiency anemia, it is recommended to consume more foods rich in iron and protein, such as eggs, soy products, poultry liver, kidneys, blood, kelp, and nori. Eating fresh fruits can also help enhance iron absorption.
