In the last three months, I've managed to tighten up my control significantly. To give you some context, my overall average BG hasn't shifted, but the standard deviation was 3.7 in the 12 weeks to 3rd March, and is now 2.6 over the 12 weeks to last Sunday. The graphs below show it better. Better control, that's what we're all after, right? Well, it turns out it's not quite that simple... I went to have my retinal photography today, and it was found that there's been a lot of cholesterol leakage - more so than in the past. The lovely woman who did it said that, in her experience, when patients tighten up their control, their eyes often get worse before they get better. Does anyone else have experience or knowledge of this? Also, I can't help wondering whether my ketogenic diet is having an effect. My cholesterol score has always been around 4, but it hasn't been tested since starting the diet.
