Several factors can contribute to high blood sugar (hyperglycemia) in people with diabetes. Factors include food and physical activity choices, some medications, and skipping or not taking enough glucose-lowering medication. In addition, illness, injury, surgery, stress, menstruation and menopause can influence blood sugar levels.

Physical or emotional stress triggers the release of hormones that can cause high blood sugar levels. For women, menstruation and menopause cause hormonal changes that affect blood sugar levels.

Regular blood sugar testing will expose patterns and help you and your health care team to control your diabetes. If you experience persistent hyperglycemia, talk with your team about adjusting your diabetes treatment.
