I was diagnosed as Type 2 a year ago. My current HbA1c is 41 (down from 61 a year ago). I control my diabetes with a low carb diet and exercise. Healthcare professionals never mentioned blood testing but I bought a finger pricking blood testing device after joining this forum. I have being paying about £24 per week for Libre 2 since last September - health professionals discouraged me because if they didn't they perhaps felt they would have to fund it.
I find the readings to be next to useless and have no idea why I still use it. It might as well just say Low, Medium or High. I have had about 6 sensors replaced by Abbott when I ring up and complain that the readings are consistently higher than finger prick readings or the sensor has packed up early. In one case the sensor was consistently too low. In fairness, Abbott never quibble and immediately send me a replacement sensor. I figure that they cost Abbott peanuts and if they have a customer daft enough to pay £24 per week they want to keep me doing it!
I love the concept but given that a sensor is replaced every two weeks there is no calibration - no way of knowing whether your blood sugar has increased or a new sensor is responsible for higher readings.
The one area where I do value the sensor is the continuous monitoring which finger pricking cannot provide. Initially I was eating porridge for breakfast and found a finger prick two hours after breakfast showed my blood to be fine. However, Libre drew my attention to my blood sugar spiking dramatically within 30 minutes of eating porridge. I have learned that I cannot tolerate cereal, potatoes, pasta, rice, alcohol or ordinary bread. I do eat Liv Life bread which was mentioned on this forum. 7g of carbs per small slice and only available from Waitrose.
I started off at 14 st 5 lbs last year and within 3 months on a low carb diet and walking several miles a day I was down to 11 st 6 lbs. The trouble was I wanted to stop losing weight at about 11 st 11 lbs and found little help on this forum. However, my wife found recipes fore low carb cakes and cheesecake and I now successfully use these to control my weight at around 12 st 0 lbs.
I have just bought another 4 Libres for £193 so I am committed for another couple of months. Hopefully their accuracy will improve over time.
