Jobs’s reference to a “hormone imbalance” in the letter alone is too vague and general to diagnose, agrees Bruce White, a cell biology professor at the University of Connecticut Health Center in Farmington. But he says that if Jobs has a hormone imbalance that is affecting the amount of proteins in his body, it points to a possible problem with production of the hormone insulin (by the pancreas) and the possible onset of type 1 diabetes (which is rare but not unheard of in adults).
