Analogy

There is an organ in the body that can suffer from a degradation of function but still appear normal. I speak, of course, about the penis. If you have erectile dysfunctionality, this can be caused by a decreased blood flow into the penis, and an increased blood flow out of the penis. Drugs like Viagra act by dilating the blood vessels leading out of the penis, allowing the penis to stay erect even if there is a less than optimal blood flow going into it. The kinking or partial blockage of the artery that leads to the penis, causing the decreased blood flow into it, is thought to occur in the pelvic region somewhere quite far away from the penis. It's not the penis's fault. An examination of the penis itself could not tell you conclusively if its owner was erectiley dysfunctional. The penis appears to be healthy and performs one of its functions, urination, well enough; it just doesn't work optimally for sex.

My theory is quite simple: physical pressure on the pancreas, or on something that leads to or out of the pancreas (nerves, blood vessels), is causing the pancreas to malfunction, or to function slowly, without actually harming the pancreas. Should the circumstance that is preventing optimal pancreatic functioning be relieved, the pancreas will again function normally and Type 2 Diabetes will go away. That is my theory.
