What will happen when a diabetic skips their rapid-acting insulin?

Skips insulin: If you skip insulin occasionally by chance that should be easily corrected at your next meal. If you skip insulin when you are out eating with friends or family you need to know that it is easy and safe to give yourself an injection through your clothes while sitting at the table. If you feel that embarsses you, you can go to the ladies/mens room and give the injection to yourself there.
