Some time ago, Beijing Daily published an article \”One in six pregnant mothers has diabetes\”, which introduced that the incidence of gestational diabetes in my country is about 17.5%. After reading this article, I suddenly remembered that in the database of pregnant women with hepatitis B established by the obstetrics and gynecology department of the hospital, the incidence of gestational diabetes is also very high. So, what is the incidence of gestational diabetes in pregnant mothers with hepatitis B? In this database, the number of mothers with complete records of hepatitis B has reached 1,485, of which a total of 433 mothers with hepatitis B were diagnosed with gestational diabetes during pregnancy.
