Generally, adult male hemoglobin <120g/l and adult female hemoglobin <110g/l are anemia. Anemia can be divided into four levels according to the degree of hemoglobin reduction. Mild: hemoglobin>90g/l, moderate: hemoglobin 90~60g/l, severe: hemoglobin 60~30g/l, extreme: hemoglobin<30g/l.

Your hemoglobin is only 72, so physiological fluctuations are not considered, but moderate anemia. Moreover, it has exceeded the ability of food treatment. It is recommended to seek medical treatment for further diagnosis and treatment.

Possible reasons:

(1) Anemia caused by reduced red blood cell production: (If your white blood cell line data are normal, this reason may not be considered)

1) Bone marrow hematopoietic failure: aplastic anemia, myelofibrosis and other associated anemias. 2) Anemia caused by lack of hematopoietic substances or impairment of utilization: such as iron deficiency anemia, sideroblastic anemia, megaloblastic anemia caused by folic acid and vitamin b12 deficiency.

(2) Anemia caused by hereditary defects in red blood cell membranes and enzymes or excessive destruction of red blood cells caused by external factors, such as hereditary spherocytosis, thalassemia, and paroxysmal nocturnal hemoglobinuria. , abnormal hemoglobinopathy, immune hemolytic anemia, major surgery for cardiopulmonary bypass and hemolytic anemia caused by some chemical and biological factors. (Those with this factor often have more obvious corresponding clinical symptoms)

(3) Blood loss (common): anemia caused by acute blood loss or chronic blood loss such as peptic tract ulcers, hookworm disease/tumor, etc. (Symptoms such as black or bloody stools, hematemesis, long-term abdominal discomfort before or after meals, and obvious weight loss in the past six months may be considered)

I hope these can help you.
