Can a cold cause blood sugar to rise?

Patient's question:

Diabetes for 5 years, recent cold, blood sugar increased, is it related to the cold?

Doctor's answer:

Hello
A cold can cause blood sugar to rise or become unstable. High hemoglobin A1c is not closely related to a cold. It is recommended to recheck fasting blood sugar and postprandial blood sugar at two hours, and then adjust the insulin dose according to the specific condition under the guidance of a doctor. Monitor blood sugar regularly, maintain stable blood sugar levels, and prevent the occurrence of complications. Pay attention to diet control in daily life, have three meals at fixed times and in fixed amounts, reduce fat and sugar intake, eat more vegetables, strengthen physical exercise, and maintain a good mood.
Wishing you happiness!
