Doubt about children's diabetes

Hello my niece was detected with diabetes approx 6 months ago and they studied and it came out that he had type 1 diabetes but that he had symptoms of type 2 bone I don't understand that.Another thing always brings sugar in 200, 250 and derrepeating from one moment to another is lowered to 37 and begins to tremble.This is normal how much it should bring of glucose is 11 years old.

@eloisacv, the girl can have diabetes 1 and have developed insulin resistance.Is overweight?
As for glycemia, because those figures are not normal, of course.And the range of glycemia must determine its endocrine.
And if it has had 37 glycemia, that is a good hypoglycemia, which can be serious, even mortal.Their parents need a lot of diabetological education, if they do not have access to a specialist nurse because they will have to study a lot on the websites and forums that exist.But of course, you have to discriminate the good of the bad.

Look, when one debuts there is a phase called honeymoon.That at the beginning of insulin treatment it seems that the high needs fall.It is as if the pancreas had reservations, but sooner or later they end, and the reserves can last weeks, months ... it depends on each one.
Another issue is to adjust the insulin doses to the sensitivity of each diabetic (there is a rule to do so), also the moment of the day influences since in the morning we are all more insulin resistant.Then, there are kids who are more sensitive to insulin, the case of my son who has been bombing for 3 years, so that the basal amount and the Bolus were adjusted for schedule.Like a medium units ball it would be more appropriate.
I can spend a book in PDF of diabetes in pediatric age.My Crio is now 12 years old, debuted with 3 years, everything has changed a lot and new technologies help a lot.
Although diabetes is a roller coaster, you have to learn to live with it and knowing it is like control, you have to study the graphics of the little one and read a lot.And above all that each diabetes is different, but you can always.
Encouragement !!!!
