My mum takes Humalog Mix 25, 9 units in the morning and 3 in the evening, with extra NovoRapid to counteract any highs.
This is because she is elderly and cannot cope with too many injections in a day because calculating it all is a bit too confusing and she has memory problems so it is safer this way.
This regime is working ok most of the time but sometimes she is a bit too high most of the day, despite not eating very much (she never eats much at all).
However, a few times now we have experienced a worrying phenomena:
Suddenly, without any insulin injection, her blood sugar will start to shoot down by something like 5 in one hour and then will continue to power downwards for around 2 days. She has to take something like twice as much carbs as usual to just stay above a hypo. One day she kept going under 3 for around 12 hours. She has lost her sensitivity to hypos so she did not really notice!
Could this be the insulin getting stuck somewhere, not working, and then coming out all at once? What other problems might be causing it? I am worried that if it happens at night we will not notice and won't be able to treat it, so am considering getting some kind of CGM system. It has happened 3 or 4 times in the last 4 months.
