During the current Covid-19 pandemic, Oaklands Health Centre has created a help sheet for self-management of your diabetes when unwell. Please see below guidance from the Primary Care Diabetes Society:



  • Blood glucose levels can rise during illness even if the person is not eating
  • Advise to increase blood glucose monitoring if the person has access to it
  • Diabetes medications (sulfonylureas and insulin doses) may need to be increased temporarily during illness to manage these raised glucose levels.



  • NEVER stop insulin or oral diabetes medications*
  • Insulin doses may need to be increased during illness, especially if ketones are present
  • Specific advice for people on insulin therapy is available



  • Ensure the person maintains hydration and carbohydrate intake
  • If the person is not able to eat or is vomiting, advise to replace meals with sugary fluids
  • If blood glucose levels are high, maintain fluid intake with sugar-free fluids
  • If blood glucose levels are low, encourage regular intake of sugary fluids



  • In type 1 diabetes, advise to check for ketones every 4-6 hours.  If present, check every 2 hours
  • Give extra rapid-acting insulin doses (in addition to regular doses) based on total daily insulin dose if ketones are present
  • Advise to drink plenty of water to maintain hydration and flush through ketones

*Metformin and SGL2 inhibitors may need to be temporarily stopped if at risk of dehydration and stopped immediately if Covid-19 symptoms develop.  Contact NHS 111 for medical advice or in an emergency call 999.
