There are four types of blood: A,B, AB or 0 and also a Rh factor
which can be either positive or negative for each blood type. The
notorious Nazi doctor Otto Rehe was the reason why the effect of blood
types on human health was not studied for a long time. He claimed that
Type A is characteristic for Aryans, and the type of their enemy was B.
Anyway, recent studies have proven the link between a blood type and
certain diseases.
Blood type A
People with this blood type are more fertile but also prone to drinking
more alcohol. They have an increased risk of stomach cancer compared to
other blood types, especially if they are smokers or if they drink
alcohol very often. Women who have this blood type can become pregnant
even in older age since they have a larger ovarian reserve. People with
blood type A have predisposition to alcoholism and Obsessive Compulsive
disorder too.
Blood type B
These people have good metabolism however they are more prone to ulcers.
Other health conditions linked to blood type B are memory problems and
senility and Alzheimer’s disease in older age. Bacteria caused
inflammations are also often. Still, not everything is bad about this
blood type. People with blood type B have a very fast metabolism, they
respond well to exercise which leads to easier muscle building.
Blood type 0
Blood type 0 has low risk of getting heart disease and stomach cancer
but an increased risk when it comes to stomach ulcers caused by
Helicobacter pylori. Having this blood type means you have the smallest
risk of dying from malaria but you are more vulnerable when it comes to
cholera. Men with this type are more prone to obesity and women have
fewer and poor quality eggs which means they are less likely to conceive
naturally. A good thing about this blood type is that having it means
you are resistant to stress, because in people with blood type 0 the
stress hormone cortisol to drop quickly after experiencing traumatic
events.
Blood type AB
People with this blood type are more at risk of heart attack and
developing a heart disease, digestive problems, such as chronic
gastritis, Cronh’s disease etc. Particularly women with type AB are at a
greater risk of suffering from a condition caused by high blood
pressure – pre-eclampsia and occurrence of ovarian cancer.
According to studies, cortisol levels also normalize faster in people
with blood type AB and they are less prone to having problems with
vision.
