Pediatric fava bean disease, or glucose 6-phosphate dehydrogenase deficiency, is a common genetic disorder that does not disappear on its own with age. If the disease does not cause symptoms, no treatment is usually necessary. Prevention is important, such as avoiding the consumption of fava beans and their products, such as bean paste, and avoiding the use of antimalarial drugs, sulfonamides, antipyretic and analgesic drugs, uric acid-lowering drugs, skin disinfectants, nitrofuran compounds, etc., to avoid triggering hemolytic anemia attacks. If hemolysis occurs, the situation is more critical and requires immediate blood transfusion and application of glucocorticoid therapy, which may lead to acute renal failure and endanger life if not treated in time. Crohn’s disease is hereditary, so it is recommended that premarital checkups include testing for related enzyme deficiencies to predict the risk of fetal disease after marriage and to intervene in advance. Although sericea cannot be cured, as long as care is taken to avoid triggering factors, it can reach a state that is indistinguishable from that of a normal person, so parents should not worry too much.
