Or did type 2 mainly go undiagnosed then?
I doubt it. I was looking into the history of diabetes a while back, out of curiosity regarding when we adopted the terms 'Type 1' and 'Type 2'. This terminology is actually quite recent-- adopted as the norm I think in the early 1990s?
But, even before the invention of any type of testing strips (let alone the invention of the HbA1c test), it was easy to diagnose diabetes: sugar in the urine. The doctor-- or, if he was lucky enough to have a student, his student-- would taste it ...
And the difference between what we now call Type 1 and Type 2 has also always been easy to recognise. Before insulin was discovered and used as treatment, Type 1 was invariably fatal and fairly quickly-- with little or no insulin, you literally starve to death no matter how much you eat. Significant unintentional weight loss is still a key clinical diagnostic criterion for Type 1.
What we now call Type 2s were easily identifiable as those diabetics who did not suffer from unintentional weight loss but did develop the classic complications of diabetes: poor wound healing, diabetic neuropathy, diabetic retinopathy, etc.
We had good discussion about this week or 2 back about how our lives are different now to decades before, consensus was we are less active now than before in work & didn't have as many cars then so it was shanks pony to get to work & school.
Big difference also is how we eat, people cook less at home & rely more on convenience food, not everyone but it has got worse given amount of fast food outlets, cafes restaurants in our high streets.
Indeed.
Transistor asked "How did you make people walk?" Easy:
50 years ago, more people lived in environments that encouraged and facilitated walking-- to school, to shops, to work, to your local train station or tram stop-- and far fewer people had cars.
But then, for 50 years, we've had policies which have actively encouraged car use and made it much easier and more convenient than walking or cycling or taking public transport. In fact we've had policies which, for many people in many parts of the country, have made it practically impossible not to use a car.
What we need-- for the sake of people's physical and mental health, and for the sake of the environment-- is to reverse this, asap. Walking and cycling and public transport need to be made much easier and more convenient than using a car.
This is not rocket science; we've done it before, and we can do it again.
