Novorapid & Levemir

Not a lot to report today, so thought I would tell you a bit about the insulins that I take. For those of you who are type I diabetics, this will be dull and you will probably know all about it, but for others, it may be good to see what is involved. Apologies if the picture below makes you feel uneasy, but it shows what an insulin pen looks like.

The needle attached is the smallest they do and is 5mm. The dial on the right is used to select the amount of insulin you want to inject. You then press the button and it clicks until the right dose is selected.

This insulin is called Novorapid. As the name suggests, this is a rapid action that starts working in 10 to 15 minutes. It peaks (as far as I can tell, although opinions on the net vary) in just over an hour and can be in the blood stream for 3-5 hours. I have also read that it can be gone in 2 hours, so am not sure about this figures. Novorapid is taken before meals and means that you can vary the times of your meal and if you want a meal high or low in carbohydrates you can change your dose accordingly. The technical name for this type of insulin is a bolus insulin.

The other insulin that I take is called Levemir. This is taken using a pen that looks the same as the Novorapid, except that it is green. It is an insulin analogue. This means that it is an insulin molecule with another molecule (glargine) attached. Although I can't find the exact mechanism at the moment, it appears the glargine molecule changes the solubility of the insulin. If the insulin doesn't dissolve in the blood stream, it can't be absorbed. The glargine molecule is gradually changed by the blood stream and dissolves leaving the insulin also to dissolve. This takes a number of hours and is gradual. In this way the insulin gets released over time. This is about 24 hours depending on the dose. Levemir is a basal insulin, i.e. it controls your baseline insulin. Lecture over!

Other events of note, was my successful cycle to and from work yesterday. It was hard work and my legs ached at the end, but it seemed to have a positive influence on my blood glucose and also made me feel good in myself! Didn't cycle today as it was throwing it down with rain and I am showing some people around the factory at 19:00 today so wanted to have time to have supper at home and come back.

The training course at work is still ongoing, therefore the buffet leftovers keep appearing. Today, they can't have been hungry as the picture of the left-overs shows:

As my levels were a bit high at lunchtime, I didn't eat any of it. The site secretary however sent me an email to say that she had saved me a couple of cans of Diet Coke as compensation. I was touched!

Finally, Abby wanted to come to work with me today. As it was raining she insisted on putting her wellies on with her dressing gown! Picture below:
Threw a bit of a tantrum when I said she couldn't come. What a confusing world it must be for a toddler, but I love her to bits!

Abbott dX 2022 Barcelona - "Make it Count"

For the past four years I've been invited by Abbott to a conference bringing together people with diabetes from across Europe to discuss various topics.  The first year I was meant to attend, it was my 'man v horse' year (the horse won!), so was unable to attend and then the pandemic hit so two further dX's were held virtually.  I was fortunate to be asked to present at last year's session.  This year's event was back in-person and held in Barcelona, coinciding with the latter part of the ATTD conference.   At this point, I must make it very clear - Abbott invited me to the 2022 European Diabetes Exchange forum (dX), that took place in Barcelona.  I attended this two-day event to connect and interact with inspirational and influential people in the diabetes community.  Abbott paid for my ticket and accommodation. #InvitedbyAbbott.  This is formal and it needs to be - I have not been required to do anything by Abbott as a result of my attendance and I hope that m

4.0!

Took my levels this morning and they were at the magic 4.0mmol/l level (72 in US units)! Had a biscuit in celebration! Latest graph above. Seems less predictable than I thought, but at least I am now generally below 10 most of the time. I believe I am however in the 'Honeymoon Period'. This is the time when the body is still producing a little insulin and therefore your levels are easier to control. I don't think that it lasts long. A thick blanket of snow has fallen during the night. I was meant to be going to London today, but I think I'll give it a miss. My daughter (2) saw the snow and got very excited. She had not been out in snow before. We had an excellent half hour out the front of the house making tracks and getting cold! In my nice warm office now drinking a big mug of tea and looking at the snow continuing to fall. Won't be late home tonight.

Freestyle Liberating

So,what's all the fuss about? Today's graph with two Nutella-covered wraps - no Low Carb here! The Abbott Freestyle Libre is a paradigm-changing piece of medical equipment.  It has been warmly embraced by many of the diabetic community since its launch almost three years ago (its birthday is on 16th October).  So what's all the fuss about and is it justified? In my opinion, yes , but with some important caveats, especially with how you use it and interpret the results.  These are my tips for getting the most out of it: Use it for trends - stop thinking you need to compare it to other meters.  The only reason you should continue to test traditionally is to meet requirements of DVLA.  OK, if you are hypo-unaware, I can see logic in checking.  Yes, it can be 'inaccurate' but that's hard to quantify.  If you're far enough into your journey with diabetes, you should have a fair idea of what the scan is going to show.  If it doesn't match
