Hi, I did a DAFNE course in 2005, and have been 'doing DAFNE' ever since, except I've been lapsing for the past few years and my HBA1c has been steadily increasing. Obviously this has to do with my non-adherence to DAFNE principles (which are great in theory, but most of the time it's difficult to keep motivated and, to be honest, thinking about avoiding horrible complications is not really such a great motivator as it tends to just leave me feeling a bit depressed). However, there is another issue that I have, and that I've had since I was first diagnosed with Type 1 (I was 30 at the time). This is that I think I digest food quickly, and that the rapid acting insulin that I take (Novorapid) is too slow and doesn't match my digestive process. My blood sugar seems to rise to very high levels for about an hour after taking the Novorapid, and I've always been told that my blood sugar will rise and that this is unavoidable. I'm pretty sensitive to insulin and hypos and am on 1:1 ratios - I think that if I increased my ratios I'd get more hypos. I've been trying to find literature about this, but the closest I got was an article about the timing of the injections. Is there any information out there about the timings of digestion and rapid acting insulin? And how high should blood sugar rise after eating, even after taking rapid acting insulin? |

Hello Sheila. I'm a brand-new graduate, so don't feel particularly qualified to advise you (yet) as I'm still just getting my head around the principles involved, but we were told that Novorapid starts to work within 5 minutes and carries on working for 2 to 3 hours. I too notice a high level about an hour after a dose of Novorapid at breakfast (reading taken pre-driving) but it's always down again before lunch, so I haven't worried about it. Hope that's helpful? |

Something I have had great success with recently after hearing about it from Gary Scheiner (author of Think Like a Pancreas) is injecting insulin directly into muscle rather than fat. It gets absorbed twice as quickly. I'm on Humalog which takes about 3 hours to fully absorb, and 90 minutes to peak, but injecting into muscle means it is all used within 90 minutes with a peak at about 45 minutes. |

Experimenting with the timing as Garry suggested would be my personal choice. Allowing the insulin to get in and going strong would be advantageous to your quick digestion. I injected, and still do bolus with pump, 30 minutes before I eat, in order to get the mid meal spike down as low as possible, so 1.5 to 2 hours later. It works a treat. So definitely worth experimenting with. |

Hi everyone - thank you so much for your interest and speedy replies! The injecting into muscle sounds intriguing, but isn't it a bit sore? And wouldn't I need longer needles (I have 6mm at the moment)? It definitely sounds like something I'd look into, though, thanks for the suggestion. My BG seems to rise to as high as 19 or 20 an hour after I've eaten, and that's when it's at between 6 and 7 before I eat. This can't be right, surely? I wondered whether I should change my ratios, but it seems to be more to do with when it's rising rather than the amounts? I'm now also seriously considering taking my bolus dose early, though this might not be achievable each time I eat, as sometimes it's more spontaneous than others! Thanks for all your suggestions. |

Hi The important BG is the 1 after 4 to 5 hours after your QA dose this is the BG you correct from. The only time you would correct after an 1 hour period is when its below the starting BG number the correction then would be with a QA carb. If you find the number to high and it worry's you don't test at this stage unless you feel hot and sweaty which points to you been to low. The injection into muscle worry's me, over time even a single injection would cause sores which take a long time to heal. I've seen many people who injected into the arm with very sore and not good looking brusing But this is new to me,I never over 40 yrs injected directly into muscle. I'm glad i'm now on the omnipod 2 MDI sounds like a medieval torture. |

When our dose adjusting, then the pre meal test is the most important one, but once that's all done its good to go after the mid meal numbers..... |

When you inject before having a meal you risk putting yourself in a position where for what ever reason you can't complete your meal. |
