Sorry to hear about your wife’s elevated glucose levels
@Simonthir
And condolences for the loss of her mum / your mother in law.
Hope she is feeling much better today and her glucose levels have returned towards normal. Stressful situations and heightened emotional states can have an impact on glucose levels, so things may be more erratic than she is used to for a while, and she may need to adjust doses, or just check more frequently.
I’m not sure if there is any ‘proper’ clinical evidence to back this up, but my lay observation over the years seems to suggest that some people are more prone to ketones, ketosis, and DKA than others. My clinic warned me about the risk of DKA when I moved to pump therapy, because something like a blocked cannula can put you at risk as you don’t have long acting background insulin as a back up, only rapid insulin is used. The suggestion was that things could escalate within 4-6 hours.
But my experience of cannula fails is that even if I’m in the 20s for hours and hours my ketones thankfully remain low/negligible, and so far I’ve never experienced DKA in my 30+ years of T1.
I’m not sure how prone to developing ketones / ketosis your wife is, and whether DKA has been a problem in the past?
It is always wise to be careful as DKA is so serious, but knowing your wife’s history with ketones may offer some reassurance in the early hours if this were to happen again?
