Blood sugar history proves vital for people with diabetes who catch Covid

10 January 2022

People with type 2 diabetes who contract Covid-19 are nearly twice as likely to go to intensive care if they have a history of poorly managed blood sugar levels, according to a study in BMJ Open Diabetes Research and Care.

To identify those who may be at a higher risk of hospitalisation, researchers in the US investigated the associations between blood sugar levels, the impact of common medications – such as insulin, ACE inhibitors, angiotensin receptor blockers and corticosteroids – and Covid-19 severity.

They found that those who had poorly managed blood sugar levels over a two- or three-year period were more likely to need hospital treatment.

The study looked at records for more than 16,000 people with type 2 diabetes and Covid-19 between 2017 and 2020.

Corresponding author Deepak Vashishth said he hopes the insights will ‘aid physicians in better treating and managing high-risk patients’.
