No blood-sugar reading is ever a hypo: they're not the same thing at all. A hypo is something BEHAVIOURAL.
The fact that, etymologically speaking, 'hypoglycaemia' means 'low blood-sugar' is neither here nor there: there is just (though undoubtedly so) an important ASSOCIATION between low blood-sugar readings and the occurrence of hypos - hence the use of the word 'hypo'.
The important association involves symptomatology. A low blood-sugar reading is merely one symptom of a hypo, which may or may not be occurring.
I may feel a hypo coming on, and quickly drink a large glass of orange juice. Then almost immediately I'll start to feel better. But if I also immediately test my blood-sugar (using a meter) then I may very well get a reading of, say, 2mmol/l. And yet I'm certainly not then having a hypo on account of the large glass of orange juice I just drank!
Eating rye bread throughout the morning seems to keep a certain amount of carbohydrate constantly, slowly, leeching into my blood-stream. And this, I believe, is what prevents my blood-sugar from ever CRASHING.
So I can happily spend the day getting moderately low blood-sugar readings (using the far more economical visually read strips, I hasten to add) without any problem at all.
How healthy this practice may or may not be in the long term is, I understand, a debatable issue. I've heard about, and seen, evidence both ways.
Also, it is often claimed that by constantly having lowish blood-sugar one loses one's warning symptoms of a hypo. Well, with regard to that, I can only speak for myself. When I was first diagnosed with diabetes 30 years ago, and began taking insulin, I certainly had warning symptoms that I never get now: palpitations, sweating, ... etcetera. But I lost those kind of warning symptoms NOT VERY MUCH LESS than 30 years ago!
And I'm still here.
If, instead of the kind of diet I have, you spend your life eating white bread and potatoes (etcetera, etcetera), then I would agree with that professor (though certainly not with his form of expression): any blood-sugar reading below 4mmol/l is EFFECTIVELY indicative of the occurence of a hypo.
I don't think that it is a highly significant linguistic issue. From the many blogs I have read on this site, most people, if not all, differentiate between low bG and 'hypos' using the latter to indicate physiological symptoms. 'Hypo' has become a term which many people, including myself, are comfortable with in describing the symptoms.
One could make a similar argument for 'low-carb' diets. My daily carb intake is down to 250g per day, my bGs are good, and I am losing weight like many others. Therefore, I must be on a low-carb diet and the definition of 'low carb' must be from approx 30g-250g per day, according to others on this site and my own personal experience. Are you happy with that definition?
