Three years ago, before I started tighter carb counting and bolus calculating with IC ratios, I was mowing the lawn mid morning and didn't feel too great.
So went up to my bedroom where meter was and measured .. 1.8 ..whoops that doesn't sound too good, better get some food. But it must have dropped very fast and I instead went back into the garden confused. A visitor at next door's front door saw me staggering about and asked if OK, and of course I replied "yes thanks" .. stupid me but brain now struggling to be rational.
Don't remember anything after that, but woke up two hours later on the garage floor with three paramedics leaning over me!! It seems I passed out in the garage, hit a ladder on the garage floor and there was blood everywhere. I was only found when another neighbour saw me lying there and then my wife came to find me since it was lunchtime. I came round in about 20 minutes or so after glucogen injection and all OK after that.
Since converting to tighter control (MDI + tight carb count + bolus based on ratios + 100g carb diet), overall BG better (~6.5% instead of ~ 7.5%) and hypos now a thing of the past. I've been T! for 45 years with no complications, so I thought I knew what I was doing .. but you can always learn something new it seems
