Effects of O Negative Blood Group on Health
Blood groups are determined by antigens which can be found on the surface of red blood cells. There are four main blood groups named after the antigens that determine them: A, B, AB and O. The Rh factor (an antigen in red blood cells) also has implications in determining the blood group. People can be either RH positive (if they have the antigen) or negative (if they don't have it). The O negative blood group is the rarest possible. It can be found in approximately 7% of all people. The incidence of this blood type is higher among Caucasians and very low (under 1%) in Asians.
Having O negative blood group makes a person very special. This blood group is called a "universal donor" because transfusions with this type of blood can be done to people with any other blood group. Those with O negative blood group can literally save lives if they decide to donate, but they can only receive blood from donors with the same blood group. Otherwise said, O negative blood group is preferred in case of transfusions.
Implications of O Negative Blood Group on Health
There are theories which claim that personality is defined by the blood group. According to Japanese conventions people with O negative blood group have strong leadership abilities and are very confident. They are also independent, loyal and passionate in their personal life and competent in their professional one.
Other theories believe that diet should be established taking into consideration the blood group. People with O negative blood group should eat foods with a high content of protein like meat, poultry and dairy products. They should also consume fish, vegetables and fruits, but they would better avoid legumes, beans and grains. The blood type can apparently determine predisposition to certain disease. O negative blood type can enhance the chances of suffering of thinning of the blood and hypothyroidism.
The blood group has serious implications on the health of unborn babies and their mothers. If the mother has O negative blood group and the father is Rh positive, the child can be either Rh negative or positive. If he's negative, like the mother, there isn't any problem. If he's positive on the other hand, complications might occur because the immune system of the mother fights against him. This can have dangerous consequences on the health of the unborn baby and the mother. It can be solved if the mother receives specific antibodies in the last semester of her pregnancy.
People should always be aware of their blood group because it can be of help in case of hospitalization or pregnancy and it can give important clues on the best diet and the most likely to appear illnesses.
