Blood types have four groups: A, B, AB and O and Rh factor that separates them from positive and negative.
Studies on the importance of blood type on humans hasn’t been studied for a long time. According to him, the predominant blood type of their enemies was the type B. However, many recent studies have shown the relationship between certain blood types and diseases.
Blood type A – more fertile, but prone to drinking
People that have this blood type have a higher risk of stomach cancer. Women with blood type A have more great number of eggs, so it’s more likely they can become pregnant even in the older age. But women with blood type A have a higher risk of stomach cancer, especially if they smoke and if they frequently drink alcoholic beverages. There is also a link between blood type A and susceptibility to alcoholism, and also to Obsessive Compulsive Disorder.
Blood type B – a higher risk of ulcers, but better metabolism
People that have this blood type have a higher risk of developing pancreatic cancer. Also, people that have this blood type have a bigger risk of problems with memory, as well as the onset of senility and Alzheimer’s disease in later years. However, for them not everything is so black, because they usually have a faster metabolism, build muscle easily and respond well to exercise.
Blood type O – lower risk of heart attack, but lower fertility
People that have this blood type will have a lower risk of heart disease and stomach cancer. But they have a higher risk of getting stomach ulcers caused by Helicobacter pylori bacteria, and men with this blood type are more prone to obesity. For blood type O there is small possibility of dying from malaria, but people are more vulnerable to cholera. For women of this blood type the chances are bigger to have fewer and poorer quality eggs, so the chances of conception are smaller. The good news is that people with blood type O are very resistant to stress – after traumatic events, their levels of the stress hormone cortisol, quickly drops.
Blood type AB – prone to heart attack, but with better appearance
Women that have this blood type have a higher risk of occurrence of ovarian cancer, and women with blood group AB are at greater risk of developing a condition of high blood pressure – pre-eclampsia. People that have this blood type have bigger risk of heart disease and heart attack, but also digestive problems such as are chronic gastritis, Crohn’s disease …
Studies have shown that after traumatic event, the level of the hormone cortisol long remained stable, which makes them less resistant to stress. But they are less prone to vision problems.
