Clinical terms

Sick day action plan

A sick day action plan is a written plan, made with your diabetes team, that tells you how to manage glucose, ketones, food, fluids and medicines when you are unwell.

Also called

Formerly called

What it means

Illness and infection usually push glucose up, even if you are eating less. Your plan sets out how often to check glucose and ketones, how to adjust insulin, what to eat and drink, and when to seek help.

Some medicines may need to be paused while you are sick and dehydrated, such as SGLT2 inhibitors and metformin, and restarted once you are eating and drinking normally. Never stop insulin unless your plan or your doctor says to.

The ADEA publishes sick day action plan templates that your diabetes educator can complete with you.

At PDC Health Hub
