Insulin (medication) testing and occasionally skin biopsy. First line therapy against insulin hypersensitivity reactions include symptomatic therapy with antihistamines. The affected persons are then switched to a preparation that does not contain the specific agent they are reacting to or undergo desensitization. Insulin is an endogenous hormone, which is produced by the pancreas. The insulin protein has been highly conserved across evolutionary time, and is present in both mammals and invertebrates. The insulin/insulin-like growth factor signalling pathway (IIS) has been extensively studied in species including nematode worms (e.g."C. elegans"), flies ("Drosophila melanogaster") and mice ("Mus musculus"). Its mechanisms of action are highly
Insulin resistance also experienced increased insulin sensitivity and remission of type 2 diabetes. This suggested similar surgery in humans, and early reports in prominent medical journals are that the same effect is seen in humans, at least the small number who have participated in the experimental surgical program. The speculation is, that some substance is produced in the mucosa of that initial portion of the small intestine that signals body cells to become insulin resistant. If the producing tissue is removed, the signal ceases and body cells revert to normal insulin sensitivity. No such substance has been found as yet, and the
