These can include gambling, sensation seeking, risk taking, substance abuse and impulsivity. Since there is a powerful, synergistic relationship between the release of dopamine and feelings of reward, Type O is more vulnerable to destructive behaviors when overly tired, depressed or bored.

The Type O response can cause bouts of excessive anger, temper tantrums, hyperactivity and even create a severe enough chemical imbalance to bring about a manic episode. However, this finely tuned response to stress, so vital in early Type O’s, is not always so beneficial in modern times. The legacy of your Type O ancestry causes an immediate “fight or flight” response in people of this blood type. Read More Blood Types, Fats and the Intestines Many grains also contain reactive proteins called lectins that can ramp up the type O immune system, resulting in unwanted inflammation and auto-immunity. However, these very same strengths come at a cost: in Type O simple carbohydrates, especially from grains, are more easily converted into fats and triglycerides. These digestive factors greatly enhance the ability of type O to not only metabolize the choelsterol in animal products more efficiently, but also greatly increase their ability to heal their digestive tract and better assimilate calcium. This is because two chemicals used by the digestive tract, an enzyme called intestinal alkaline phosphatase, and a lipoprotein called ApoB48 are secreted into the digestive tract in much higher amounts by type O's. There is also another unique characteristic of type O that is perhaps even more important: This blood type has a very well-developed ability to digest meals that contain both protein and fat. We've already mentioned the tendency of type O towards higher levels of stomach acid. These findings have been replicated many times since then. In the 1950’s it was discovered that Type O’s had about twice the instances of ulcers of all kinds than the other blood types. Blood Type O may be predisposed to certain illnesses, such as ulcers and thyroid disorders.

However, when misdirected, this innate immune reactivity can sometimes get in the way of good health. Thus, what is commonly considered a transfusion complication was, in type O, a very useful defensive benefit.

These antibodies undoubtably conveyed some survival advantage, as many of the common diseases that plagued our ancestors possessed markers (antigens) that simulated the other blood types. It is the only blood type that carries two opposing blood type antibodies (one blood type A and another against blood type B).
