I've had type 1 since age 4 and did ballet for 10 years as a child and young teenager. Managing blood sugars with exercise is the toughest part of diabetes. Sometimes the classes, especially with a lot of bar work, would actually make my blood sugar higher because muscles release glycogen (stored glucose). Does your daughter use pump or shots? If she uses a pump does she disconnect when dancing? She's probably just going to need to experiment with food and insulin timing until she finds the sweet spot with blood sugar management.

Another great resource is Gary Scheiner's online classes. He's the author of "Think Like a Pancreas" and is a long time type 1 and exercise physiologist. He offers a $30 online class on blood sugar management for exercise at www.type1university.com and in the live sessions will respond to questions.
