Despite the increase in the use of insulin pumps and continuous glucose monitors in recent years, the management of type 1 diabetes remains suboptimal in terms of glycaemic control and normal glycated haemoglobin (HbA1c) level. This article discusses the case of a child with type 1 diabetes who was successfully treated with a very low-carbohydrate diet, resulting in normal levels of HbA1c and normal blood glucose 95% of the time in a range of 70–180 mg/dL (4.0 mmol/L−10 mmol/L). Therefore, further studies are needed to verify how a very low carbohydrate diet impacts child development. To read the full article, log in using your MPFT NHS OpenAthens details.
