Exercise causing sharp drops in bg

Could it be that my pancreas is stimulated by the exercise and produces more of my own insulin as a result?

Do our muscles order glucose from our blood? Or does the glucose escape into the muscles by accident? Could I have a broken trigger that orders the glucose? Ie. My muscles think they have enough and dont call for more so it stays in my blood?

Sorry im sure this only makes sense to me, and I only just understand me

Well when you exercise you’re cells need ATP to make energy, and the more energy you need/use the more ATP must be produced by your cells.

I do not remember the whole krebs cycle now, but the more ATP you use, the more glucose you’ll need.

So the cells kind of take «more» glucose when you exercise.

I do not think you get less resistent or that you’re pancreas suddenly helps you out. It simply your cells starving to get glucose for creating enough ATP.

If Jason Fung’s theory of overflow is correct, then one would think that any amount of glucose being used for energy would help increase insulin sensitivity. After all, if the resistance is caused by the blood and tissues being chock full of glucose, burning some off makes room for more. This could explain why exercise is known to improve insulin sensitivity. Likewise fasting.

One thing is for certain, the human body is nothing short of miraculous

Hi @Fenn I have the same problem if I’m not careful, walking for 20 mins will lower me by 3 - 4 mmol/L (which can be useful sometimes), but I try to minimise this by:

1. Ensuring my BG is 7 or 8 before I leave the house
2. Sipping orange juice as I walk along (the cartons with straws are ideal, obviously don’t get a sugar free version)

P.s. I don’t have T2, so may not work for you.
