My blood sugar level is up even though I keep a consistent diet and exercise schedule What could be the cause

Answer From Stacy M. Loneman, R.N., CDCES Many factors can cause high blood sugar (hyperglycemia) in people with diabetes. Factors include: Food and physical activity choices Dehydration Certain medications, especially those that contain steroids Skipping or not taking enough medication that lowers blood sugar Taking medications incorrectly Illness, infection, injury or surgery Stress (both positive and negative stress) Hormonal changes 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. With Stacy M.
