Blood sugars keep dropping

[B17_Fan]

My mum (type 1) has been waking up with low sugars...her libre alarm has been waking her up about 6am the last few mornings. The alarm is set at 4.2

She worked out her insulin for her tea tonight.
Her alarm has gone off 3 times tonight.

She had a packet of crisps and a jam sandwich the first time it went off.

The second time she had a can of coke, 3 tuc biscuits, 2 jam mallow biscuits and a chocolate digestive

About half hour after eating, it's gone off again.
She's just had a weetabix

Obviously she's worried about going to bed. We can't work out why it keeps dropping, even though she's eating

Any tips on what we should do?
(She is gonna phone the diabetes nurse tomorrow)

Have you checked the libre reading against a glucometer? It's renowned for compression lows and also you sometimes just get a bad sensor....

I still remember a hypo I had with my dexcom (I know it's a different system but it's similar technology) once. It read low in the evening and kept going low whatever I did. When I finally checked against my glucometer I was running at 20....

Hi, I'm type 1 and it used to happen to me as well.
Sometimes the sensor has errors so it's good to check the blood sugar with a glucometer, when this happens.
If, however your mum had the hypo symptoms each time this happened she may be advised to decrease the long-lasting insulin or change the ratio for the rapid insulin.
I was advised to do this by my diabetic nurse and didn't have this problem anymore.
