My son goes low while sleeping. How can I prevent this?

Nocturnal hypoglycemia can be decreased, but not totally avoided, by adjusting insulin doses, choosing alternative insulin products (i.e., sometimes bedtime Lantus avoids middle-of-the-night hypoglycemia as does bedtime Levemir versus bedtime NPH) and sometimes using an insulin pump to accomplish the same thing. Adjusting bedtime food choices (i.e., using high fat choices like ice cream) sometimes also helps. Lastly, adjusting insulin and/or food at bedtime based upon previous afternoon/evening activity is another alternative. All these are rather complicated and it would be wise to discuss details with your diabetes team.
