Stress increases the secretion of hormones that raise blood sugar. Even when the body is sick due to illness, the excess glucose stored in the liver is released, so blood sugar rises. Depending on the drug, blood sugar or blood pressure may increase, so be sure to inform the doctor that you have diabetes when you are prescribed the drug.
Also, in the case of type 1 diabetes, if there is not enough insulin in the body, blood sugar may increase during exercise. This is because when you exercise vigorously, the stored glucose in your body is released. Therefore, if you have type 1 diabetes, you must check your blood sugar before and after exercise.
On the other hand, the rise in blood sugar between 4 and 6 am is called the dawn phenomenon. This is because the liver releases stored energy to wake the body from sleep. Therefore, if fasting blood sugar is high in the morning, consult with your doctor and adjust the insulin dose used before bed.
In women, hormonal changes during menstruation also affect blood sugar. Although there are individual differences, if blood sugar tends to rise during menstruation, you should exercise more and reduce your carbohydrate intake. If you are using insulin, it is a good idea to talk to your doctor about increasing your dose.
Insulin resistance also increases during pregnancy, which can lead to gestational diabetes. If a diabetic becomes pregnant, blood sugar rises further, so the insulin dose needs to be adjusted. The Korea Diabetes Association recommends that if you have diabetes, pregnancy and childbirth should be carried out under strict management in consultation with your doctor.
