Currently, it is estimated that 400 million people worldwide have this disease. So what is G6PD deficiency? Is it dangerous and how should it be detected and treated?
G6PD deficiency is a deficiency of the enzyme glucose-6 phosphate dehydrogenase, which causes red blood cells to function abnormally. Patients with G6PD deficiency often have an allergic reaction when they eat lentils or use certain oxidizing chemicals.
1. What is G6PD deficiency?
G6PD deficiency is identified as a recessive genetic disease on the X chromosome, children have this disease because they receive an abnormal recessive gene on the sex chromosome from their parents. Therefore, boys are more susceptible to the disease than girls. The deficiency of G6PD enzyme was determined by doctors due to a mutation in the G6DP gene at point Xq28, where there are more than 140 types of mutations leading to G6PD deficiency. These structural changes disrupt the normal structure of enzymes, reduce the amount of these enzymes in the cells and cause metabolic disorders in the body.

2. Signs of G6PD deficiency in children
Newborns at birth will be tested early to detect congenital diseases including G6PD deficiency. Newborns will be taken by doctors to take dry blood from the heel for testing and analysis. If the results show that the child has a G6PD deficiency, further tests are needed to make a definite conclusion.
For children with G6PD deficiency that are not detected early at birth, parents need to know the typical signs of G6PD deficiency in order to have the right treatment early.
Children with G6PD deficiency when eating lentils or using drugs and foods with high antioxidants will suddenly have an allergic reaction with manifestations such as high fever, headache, abdominal pain, low back pain, heart palpitations. rapid, difficult breathing, jaundice... When the child is taken to the doctor, the test will show anemia due to hemolysis in red blood cells, causing anemia leading to jaundice, yellow eyes, kidney failure. Especially when the baby has severe jaundice at 2 weeks after birth, the damage caused can be very severe, such as cerebral palsy, mental retardation...
In the case of children with G6PD deficiency, there are mild manifestations. No need to worry too much, just avoid foods and drugs with oxidizing properties, ensuring anemia is improved and stabilized. But if the symptoms are more severe and obvious, parents need to send the child to the hospital for proper treatment.
3. Is G6PD deficiency dangerous?
The enzyme G6PD is produced by red blood cells to help protect red blood cells from oxidative damage. Deficiency of G6PD enzyme, red blood cells will be destroyed by oxidants and cause hemolytic anemia. After birth, severe jaundice due to G6PD deficiency will cause many serious injuries such as cerebral palsy, mental retardation and motor retardation.Besides, if not properly treated, prolonged hemolytic anemia along with neonatal jaundice will be a serious problem that children with G6PD deficiency face. Therefore, if a child is found to have G6PD deficiency through early screening, the child should be monitored and parents should be advised to avoid allergens such as lentils and foods and drugs containing antioxidants to ensure their health. healthy for children.
However, it is not because of that that patients with G6PD deficiency are always in danger, they can still live normally with the condition that they do not use foods and foods with the ability to oxidize.
