Type 2D with CGM. Glucose showing 3.9. Low for some time. Do I have to do anything?

Do you have a meter so you can do a finger prick test to check the sensor for accuracy?
How are you feeling? Do you feel shaky or light headed?
When did you last eat or drink water?
Sometimes sensors can read low especially if they’re being compressed… were you leaning against it or lying on it?
Sorry for the many questions but more info is needed so best to advise.

Thank you. I just saw your reply. I don't have a meter. I wasn't leaning on the sensor or lying down, just noticed I kept getting an alert sign and downward pointing arrow. So I decided to eat some biscuits with sugar, even though I'm T2 and hypos aren't supposed to happen, and then I had an early supper, including a small helping of potato. I had eaten today, porridge and a rather large breakfast, after which my BG spiked, so I had a small salad and goats cheese for lunch. And I've been drinking water. So this came as a shock. But after supper, my BG is going up, now at 5.8. I just hope it doesn't spike out of control.

I was going to delete this post, as 'end of scare', but perhaps leave it up, in case this is something T2Ds need to be mindful of. My A1c has gone down significantly since October, after being high for a long time. It's now below diabetes level. Perhaps I should speak with my doctor about reducing meds. Again thanks. All good points you raised.

BG racing up, now 7.2 :(
 
On 3 x metformin 500 and dapagliflozin 5 mg.
Dapagliflozin shouldn't cause hypos (unless taken in combination with insulin or gliclazide, which you are not).
I second @Taighnamona , it's not a hypo unless confirmed with a fingerprick, especially not without symptoms.
Non diabetics drop to the mid 3's occasionally, it's no problem at all. The reason hypos are classified as below 4 is to build in a bit of extra safety for those of us who are on a medication which can cause hypos.

This really shouldn't be necessary if you didn't have symptoms.

A sensor is a wonderful tool to find patterns around food and exercise, but it's not that good at absolute numbers. My sensors usually read 1-2 mmol lower than a fingerprick, but I still wouldn't want to do without!

Well done, keep up the good work!

I self fund my CGMs to help keep me in range. I found the Libre to be inaccurate at low/ high levels so switched to the Dexcom 1+ A sensor is great for helping identify which foods spike our glucose levels and making dietary adjustments. This is very much making changes for life.
Investing in a meter would be helpful for you. Many of us find that carbs raise our glucose too high. I no longer take cereals, porridge, potatoes and strangely lentils was another that spiked me. I can take small portions of pasta or rice as part of an evening meal. Earlier in the day is a definite no no.
All food will raise glucose levels and the goal is to manage your intake so that you stay in range, perhaps 5-10 in the early days then tightening to 4-8 as you adjust your dietary lifestyle. There’s lots of info and people to help on this site. Good luck.
