Good afternoon, My 4 year old son has been having issues with blood sugars. He is having hypos as low as 2.1 and hypers as high as 17 that I've catch. He has been in hospital this week with ketones 4.3 . We have left still not knowing what is going on. Because of the hypos they point blank dont want to entertain the idea of diabetes. I certainly dont want him to be on insulin but it seems that he needs it at times. His 9very night is fine between 3.9-4.2 .He went from 3 - 16.5 yesterday he was so ill, headache , drank a gallon of water and just felt like poo. 3 hours after food he was still 12.8. I just want to know what's going on. Just wondered if anyone had that a similar situation and finally got to the bottom of it.
