Now that we've looked at some of the basics of what causes high blood sugar, which to recap are either not enough insulin or too much of it, too much insulin resistance, too much glucose being secreted by our liver, and perhaps even too much glucose being eaten, which we only touched on actually, it's now time to look at how we got here in the first place, or to have a little look at this at least.
The short answer to this question is that we know that whatever the ultimate causes of diabetes are, it's very complicated, the influencers are numerous, and there's a hell of a lot we don't know about all of this.
Explaining how something is caused though doesn't just mean that something puts you at a higher risk factor and if this happens then it caused it. This at best is a factor in the causal chain but more things need to happen than this, by definition, since it's just a risk factor. Being shot in the head with bullets isn't just a risk factor for dying, this can and almost always does kill you, although there are other elements involved such as the caliber of the bullet, where in the head one gets shot, and so on.
When one does die from this though there's no doubt it was the bullet that caused the death. If you merely live in a neighborhood that has an above average amount of shootings and you get shot well living in the neighborhood would increase your risk but it certainly didn't cause your being shot.
I'm bringing this up because there is a lot of confusion over the difference between causes and risk factors, even among a lot of scientists, where this and that is a known risk factor but it is being sold as a cause instead, for instance with the idea that eating a lot of sugar or being obese causes diabetes.
There is actually a concept called medical causation which isn't causation at all, it's a correlation, and what happens is that if this factor is correlated more strongly with the target group, for instance people with diabetes, then it's held that the factor medically caused the target.
This is pure nonsense by the way, but the real problem here is that people who push this stuff almost always have axes to grind, like for instance with cigarettes causing lung cancer. People are usually shocked when I tell them that this isn't the case at all, at least if we use the word cause correctly, as even though a higher percentage of smokers get lung cancer, a lot don't, so we know just from this, with absolute certainly, that cigarette smoking cannot cause lung cancer, even though it no doubt increases the risk, very significantly actually.
Why does this distinction matter though? It matters because we use this to blame people. Sure, certain things do carry a higher risk of something, like for instance driving a car on the highway, and you won't get killed in a highway car accident if you stay home, but we don't blame people for this, and say well it serves you right for driving your car on the highway, and that caused the accident, which is all foolish.
That's because driving your car on the highway is a socially acceptable activity, with no baggage attached to it, while something like being obese does carry with it a social judgement, so people love to look to blame you for this higher risk activity, presuming you could even do something about it, which isn't always the case.
People already tend to blame themselves needlessly already without getting a whole bunch of help from others here. If you are obese or were obese and you got diabetes, or you drank a lot of big gulps and went crazy with the sweets or whatever and got diabetes, or whatever you think you may have done to cause it, including things like being born since genetics plays a role here a lot of the time, you need to realize that no, you didn't do this to yourself, you just got dealt a bum hand.
We're not at all sure why people get dealt these hands, so don't pretend you do. You can take several people in the same exact circumstances, and one will become diabetic and the rest won't, and the rest can be obese or a big carb eater or whatever, it doesn't matter, so it wasn't that.
It's not even that it matters what happened, and even if it was your fault, which it isn't, who cares really, rational beings look forward and only look backward in order to learn, not to inflict themselves needless and foolish grief.
