From Great Britain:

My son, age two, has been diagnosed with diabetes after being incredibly thirsty for two weeks. He has been put on insulin twice a day and on the third day of his course he is at home and has started to become quite ill.

We have been told he must eat shortly after the insulin shots but this morning he refused to eat anything and then became violently sick, vomiting and diarrhea throughout the day. We are already very distressed at him having diabetes at such a young age. Is there any chance he could be allergic to insulin? We all feel very depressed. His blood sugar level was 42 mmol/L [756 mg/dl] when admitted and is now between 7 [126 mg/dl] and 17 [306 mg/dl], but this morning down to 6 [108 mg/dl].


The story of a child being diagnosed diabetic with no metabolic decompensation then developing a viral illness within 24-48 hours is very common to all pediatricians. Presumably what we are seeing is the straw that broke the camel's back; i.e., the impending viral illness with its concomitant demand for more insulin was just too much for the failing pancreas. Provided the parents have lots of telephone support and have got used to measuring blood sugars, they can usually get through at home without the need for admission. This is often a baptism of fire but a great learning experience and one that gives lots of confidence in their own abilities.

He's not "allergic to insulin." Be sure to talk to your diabetes team about these events.
