Nighttime highs and early morning blood sugar spikes with type 1 teens

I am seeking advice for a 15 year old female with type 1 diabetes and high insulin resistance under my care, we're currently facing an issue where her sugar levels remain stable between 150-160 through out the night after dinner (very low carb) then in a fasted state it rapidly begins to rise around 6am when she is fast asleep stabiliizing around 250 if left untreated until she wakes up (around 12pm), what could potentially be causing this?

Blood glucose  is derived from food and the liver. If the level is going up during the night, then the glucose is from the liver. The long acting insulin is used to control the liver, and therefore it may be that there needs to be an adjustment to the dose, and if not already, then it may need to be split with a higher dose at nighttime as opposed to the daytime. She does wake up quite late as well, and therefore waking up earlier may also help. Ultimately an insulin pump with basal control will solve the problem
