I think what he is getting at is there are multiple factors going on and that snoring or sleep apnea is not the SOLE cause. A lot of people get sleep apnea because they are obese, which typically is from eating a poor diet and not exercising or being active. Such a diet will also likely raise your blood pressure, elevate your cholesterol and even lead to being insulin resistant or full blown diabetic. Disregarding very specific cases of more isolated sleep apnea, such as yours, I think you'll find that many of these health markers are correlated with one another.
