Moderate anemia usually refers to hemoglobin concentration between 60g/L and 90g/L. If it is long-term moderate anemia, it will cause some pathological changes. For example, the patient may have headache, dizziness, tinnitus, palpitations, shortness of breath, insomnia, dreaminess or inattention, and may also have pale complexion, pale nail bed, flat nails or inverted nails. Long term moderate anemia may also lead to anemic heart disease. The patient may have arrhythmia, cardiac insufficiency, etc., and may affect the digestive function of the gastrointestinal tract, resulting in anorexia, indigestion, or abdominal fullness. Sometimes it may affect the secretion of female hormones, leading to amenorrhea or menorrhagia.
