Think I encountered this for the first time today, been off work this week which have given me a chance to be a bit more active that normal. Went out for a walk earlier and got about a quarter of the distance been walking all week and was overcome with tiredness, pressure in my head and feeling a bit shaky. BG been averaging towards the low end of 5 the last couple of weeks, today it's been closer to 6.
My diet always was very carb heavy and I've been working on lowering it for a few months, even before I was diagnosed. Generally been under 100g for last 6 weeks or so, around 50g for last few weeks and had cut out rice the last few days taking it to around 20-30g. Had some rice with my dinner earlier and feel better but haven't been out for a walk since. Fluid intake seems good, haven't been cutting down on salt but perhaps need to add more.
Has anyone encountered this when gradually dropping carbs? Will see how tomorrow goes and perhaps try cutting down on rice again. No idea if I've been in ketosis, waiting on tests to arrive. Unclear to me if I've been pushing my carb intake too low, this is something that will improve or completely unrelated to the amount of carbs I've been eating recently.
