Do you think my insulin needs adjusting? The last three weeks my blood sugar in the morning is around 100 and throughout the day 80-125. If I exercise, I fall into the low 60s. I am a 61 yr old male diagnosed in January 2012. The doctors said type 2 but the endo changed it to type 1. My blood sugar in the ER was 720 and A1C 13.9. I am taking 12 units of Lantus and 4 units of Novolog three times daily before each meal. I am on a four carb serving per meal and a two carb serving snack at night.
It’s a great question and an important one, particularly when you take insulin with your meals. Physical activity is an important part of treating diabetes. It helps lower blood glucose (sometimes in a matter of minutes), helps control weight, lower stress and keep blood glucose levels better controlled. However, sometimes it can lower blood glucose too much. The way to avoid this is to do one of two things: 1) either take a snack before you are active, or 2) decrease your dose of insulin at the meal prior to your activity. In other words, if you are planning on taking a walk after breakfast you would lower (by a small amount) your Novolog insulin at breakfast. When you are first diagnosed, it is very important to meet regularly with your primary care doctor, an endocrinologist or a diabetes educator. They can take a look at your numbers and advise you about what to do for snack and physical activity adjustments. As for your part, it will be important to continue to check your blood glucose before and after you are physically active to determine how your body responds. Remember to always carry a carb snack with you when you are physically active so that if you do go too low, you will be ready to treat it right away.
