Question on lightheadedness

I was told by a consultant (not a diabetic one) that I need to add more salt to my diet to help with dizzy spells - something I forget after years of being told to cut it down! The switch from processed foods to low carb and mostly home cooked means I have to remember to add salt now.
So possibly keto flu, maybe not enough salt in your diet? And maybe BP dropping as mine did.
Talk to your GP.

Done plenty of that, unfortunately one favorite one, now has a tail that's about 8 inches too long.
