Definition is key
True and clincally significant 'low blood sugar
' is actually not as simple as 'below a cut-off.
' for diabetics it is (we say <70 is low), bc they are on meds that can cause severe lows. But for non-diabetics/healthy ppl, sugar in 40's can be normal. It becomes a problem only if it causes true hypoglycemic symptoms- in that case, see endocrinologist for confirmation and evaluation of cause.
