While you're on the information highway, why not search to see if diabetics aren't more prone to injury than non-diabetics before spouting off? You'll find they indeed are.
It's also a fact some guys can just take more than others. It's something that cannot be controlled for the most part so not trying to say it in an insulting way, just as a matter of fact.
For example, you could take 5 hard falls and get some type injury all 5 times while I could take the same number of hard falls and never get injured. Does it make me more of a man? Of course but I digress.
I have worked in the medical field for over 20 years. I know all about Diabetes Mellitus both Type 1 and Type 2. I am going to assume you know the difference and the causes of Type I and Type II DM.
It is true that diabetics often have issues with wound healing. Cutler is not a normal diabetic. His blood sugar is better controlled than the average Type I Diabetic. In fact, it is probably better controlled than the average 30 year old. Most wound healing issues are related to the microvascular changes that occur over time. The more poorly controlled the diabetic, the more risk of these changes. The excess sugar acts as a free radical injuring the vascular walls of these small blood vessels. This tends to happen more in peripheral areas, like the feet or areas that have a high dependence on bloodflow from small vessels. That is the reason why poorly controlled diabetics tend to have a higher risk of vision loss (Diabetic Retinopathy) or kidney failure. Chronic high blood sugar also can lead to kidney failure since the kidneys try to excrete excess sugar. But this sugar level generally has to be over 250-300 which is 2.5 to 3x higher than a normal blood sugar.
It has little to nothing to do with the injury that Cutler has now and shouldn't interfere with wound healing. As long as he controls his blood sugar he will be fine with that. If there was any risk to healing it would have been with his thumb injury, the hands and feet aren't all that well vascularized in comparison to other areas of the body and he healed up fine from that injury.
The issue with injury with diabetics is more long term with patients that have been poorly controlled over years. That is why you see these old dudes with half a foot or part of a leg gone. The sugar has caused a condition called diabetic neuropathy and the vascular injury over time causes the inability of a patient to feel the injury that he or she occurs in a leg or toe. Add to it the damage to the vasculature in the feet and lower extremities and infection sets in and wounds fail to heal. To be honest, you see this more with type II diabetics than type Is. Type IIs have a bunch of other issues besides increased blood sugar that contributes to the poor wound healing.
Cutler's diabetes had nothing to do with his groin injury. You know it, I know it, you just like to make comments.
