Hypo awareness?

[LittleGreyCat]

T2 not currently on any medications which carries a high risk of hypos.
Although Dapagliflozin can carry some risk.

I have never (as far as I am aware) had a hypo.
Although my Libre 2+ has shown readings around and below 4 which I have not checked by finger prick.

So how do you know if you are hypo aware?
Are hypos inevitable on certain medications?

I am just pondering this for the future if I progress to some drug which over stimulates my pancreas, or onto insulin.
I would need to notify DVLA and state that I am hypo aware.
Which presumably means that I would have to experience a hypo and be aware of that.
Not something I have thought about much until recently.

Has everyone on hypo risk medications experienced at least one hypo?

What are the implications of being hypo unaware?
Do you just pass out, and with luck there is someone near who can supply sugar?

Hello @LittleGreyCat . Have you been prescribed different or new medication? Or still just on Metformin, which shouldn’t put you at risk of hypo.

The following link has some info that could be useful.

Hypo unawareness is used to describe a situation where people with diabetes, usually type 1 diabetes, are frequently unable to notice when they have low blood sugar, hypoglycemia.

For one reason or another I get low blood sugars. I’ve had them when not taking drugs that may cause hypoglycaemia as well as my current drug Bupropion which stimulates insulin secretion and is a known risk for causing hypoglycaemia. Looking at my CGM Libre 3 records I have had 5 recorded low blood sugar events in the last 7 days. My lowest recoded event was 3 mmol/ls . I don’t drink alcohol.

Usually I am aware when my blood sugars are going low, I feel nauseated, shaky, agitated and sweaty. I can get a thumping headache as well. If you are prone to low sugars events you get to recognize these low blood sugar symptoms and check your blood sugars. If they happen at night, and you are hypo sensitive then you will wake up. You check your blood sugars. Looking at my recoded Low glucose events , I was not aware of any of these ‘ low sugars episodes. So either my blood sugars were higher than what was recoded by my CGM or I’m not as sensitive to these events.

If you have healthy blood sugars, or If you are diabetic, but not on drugs that can cause hypoglycaemia then dropping into the mid 3’s is considered just fine. If you are fasting for more than 8 hours, according to my lab parameters for spontaneous blood sugars tests, 3.3 is the lower limit.

Risks are greater when you are on drugs than can cause low blood sugars, or if you are on insulin. Being hypo aware, means if you went low at night you would wake up, if you are not hypo aware, then the risk is you don’t wake up and your blood sugars keep falling. So CGM low blood sugar alarms are definitely a good thing.
