Am posting on our teenager's behalf, who has had diabetes for 1 year now and maintained very good control until about six weeks ago. Since then, the glucose readings are consistently high at night, no matter what he eats or when he eats; and no matter how much insulin he injects to correct those highs, or which ratio he uses, the readings do not reduce. Daytimes are fine.
He has (in consultation with his diabetes team): changed insulin cartridges; increased his nighttime Levemir, and the timing of his nighttime Levemir; changed his nighttime insulin ratio. Nothing makes any difference.
We are at a complete loss as to what is going on. Is there anything else he can try?
Perhaps also important: he tends to eat at around 7 or 8 pm, mainly (but not exclusively) slow(ish)-acting carbs, rarely more than 60 carbs. Levels stay between 5 and 6 and then rise rapidly at around midnight to >10 mmol, where they will stay (level) until breakfast. Insulin, if injected, works only after at least three hours, if at all. He wears no pump, but has a CGM...
