General information, not an individual diagnosis. Ask a healthcare professional if you are unsure about your situation.
An infection can raise blood glucose even when your diabetes was previously balanced. Tell your doctor or diabetes team about the illness; instructions depend on your treatment and your own situation, rather than one rule for everyone.
Skipped, smaller or delayed meals can also contribute to low blood glucose, depending on the medicines taken. Describe changes in eating and any symptoms; symptoms alone are not enough to establish your blood glucose level.
Find the instructions agreed with your doctor: which measurements to take, what to do according to the results, and when to contact them. Monitoring frequency is not the same for every person living with diabetes.
If monitoring is prescribed, record readings, the date, time and context: fever, a changed meal or another unusual event. This record helps the professional understand how your blood glucose has changed during the infection.
Contact your doctor if glucose stays high or you are unsure what to do. If your condition worsens, call 15 in France; do not wait for a preventive appointment before requesting help.
Afterwards, discuss the circumstances and unanswered questions with your doctor. Ask for a written plan that is easy to find and can be shared with someone close. Do not change treatment outside your agreed personal instructions.
