TORONTO -- A few months into the pandemic, doctors including Elizabeth Sellers noticed a worrisome trend — more children arriving in hospital with a sudden and severe condition called diabetic ketoacidosis. Also called DKA, it’s a life-threatening emergency that arises in those with undiagnosed Type 1 diabetes. “I have a very clear memory of one of the long weekends in the summer being on call, and having four children present with new onset diabetes, all in severe DKA,” Sellers told CTV News. “So it really brought it home to me that, ‘Wow, I think we've got a problem here’.” Sellers is one of the researchers behind a new study that surveyed eight pediatric hospitals across Canada, and noted a dramatic rise in cases of DKA during the pandemic. The study results were published in the journal Paediatrics & Child Health in April.
