Favismosis is an acute hemolytic disease that occurs in patients with hereditary erythrocyte glucose-6-phosphate dehydrogenase (g6pd enzyme) deficiency after eating fava beans. It is also known as fava bean yellow and broad bean yellow. It is common in children, especially boys under 5 years old, accounting for about 90%. It often occurs during the season when broad beans are mature. Eating broad beans or broad bean products (such as vermicelli, soy sauce) can cause illness.
Patients usually develop symptoms within 24 to 48 hours after eating broad beans, manifesting as acute intravascular hemolysis, general discomfort, fever, nausea, vomiting, rapid anemia, jaundice, hemoglobinuria, and shock in severe hemolysis. , oliguria, anuria, acidosis and symptoms of acute renal failure. The onset of the disease and the severity of the disease have nothing to do with the number of broad beans eaten. Sometimes eating 1 to 2 broad beans is not immune. Sometimes the disease can be caused by inhaling or coming into contact with broad bean pollen. Sometimes a wet nurse can also get sick through milk after eating broad beans.
The degree and symptoms of anemia in this disease are mostly severe. Symptoms generally last for 2 to 6 days. If anemia, hypoxia and electrolyte imbalance are not corrected in time, it can lead to death; but if treated in time, people can escape the danger and recover.
In low-incidence areas, the disease is easily overlooked and missed.
