hello sir,  my name is Siddhart . My blood group is O+ve and my marriage has been arranged with a girl having the same blood group O+ve . can you please tell me in detail if our baby may have some disability after some years. Actually i have seen a few O+ve cases before where, when the child is around 10 years these defects and disabilities come out and then there is nothing but to watch a child die. So kindly please help me out if i should say \"yes\" for the marriage or \"no\". thank you .
Hello Sid hart, GO ahead with the proposed marriage, if you like her. Blood groups do not determine possibility of disability for your future child. If you marry a girl with any negative(A-ve. B-ve, AB-ve or O-ve) blood group and your first child is positive blood group, then there is possibility of disease to your second child. But this can be prevented by proper treatment after first pregnancy. About the cases before where, when the child is around 10 years these defects and disabilities come out that you mention, did this occur in your relatives? In that case some genetic disease is a possibility (unrelated to blood group) and you may get an opinion from a clinical geneticist. Always better to avoid consanguineous marriage (marriage with blood relatives)
