Many factors can cause high blood sugar (hyperglycemia) in people with diabetes. Factors include:
Physical or emotional stress triggers the release of hormones that can cause high blood sugar levels. Menstrual periods and menopause also cause changes in the hormones that affect blood sugar levels.
Regular blood sugar testing can uncover patterns. This can help you and your health care team control your diabetes. If you experience persistent hyperglycemia, talk with your team about adjusting your diabetes treatment.
