Canada: gestational diabetes linked to child diabetes risk

05 June 2019

Children born to mothers with gestational diabetes could be at increased risk of type 1 diabetes themselves.

Published in the Canadian Medical Association Journal, the study of 73,180 mothers compared data from randomly selected births to those with and without gestational diabetes. ‘We found that a child or teen whose mother had gestational diabetes was nearly twice as likely to develop type 1 diabetes before the age of 22,’ said senior author Professor Kaberi Dasgupta.

‘Only a small number of children will develop diabetes before the age of 22, even if their mothers had gestational diabetes,’ added co-author Meranda Naklha. ‘However, parents and healthcare providers should consider the possibility of diabetes if children start showing signs such as frequent urination, excessive thirst or weight loss, particularly if their moms had gestational diabetes.’

A child with undiagnosed type 1 diabetes is at risk of the potentially life-threatening diabetic ketoacidosis.
