Since undiagnosed or marginal glucose regulation problems may put one at risk, it is good to be aware of potential problems. A hot topic in diet forums is Syndrome X . At that point the pancreas cannot produce the amount of insulin required to regulate glucose during digestion. Production of the overloaded pancreas may eventually decline, leading to chronic hyperglycemia. Genetic factors for insulin receptor defects may be involved with insulin resistance, and it is often associated with obesity.
Excess glucose is stored as body fat.
There have indeed been several studies that show an association of psoriasis with elevated insulin , and also with the diseases of elevated insulin. This is seen in population studies of diseases that appear with psoriasis . When the association was first published in the 1950's, the research consensus was that diabetes had no causal relationship with psoriasis. Even if these studies may have used a clinical definition of diabetes more severe than the modern classification, that would be expected to emphasize the lack of a direct connection to psoriasis, since a more extreme condition of elevated insulin and glucose levels would be expected to have more evident side effects. That isn't the case.
