Is yellowish complexion related to iron deficiency anemia?

Yellowish complexion is related to iron-deficiency anemia. It is necessary to supplement the diet with foods such as pig liver, soybeans, and longan to nourish qi and blood. Internal fluid imbalance can cause skin yellowing. Kidney deficiency, qi deficiency, or cold body constitution may lead to dull, lackluster skin, menstrual irregularities, and a tendency to feel physically fatigued and mentally drained—these are all symptoms associated with kidney or qi deficiency.
