Doctor:Yes, there are some concerns. However it is not something that cannot be prevented.

User:are there any treatment available that can be sought before they convcieve
Doctor:If your brother's wife is rH negative and the first child happens to be Rh positive
Doctor:her gynecologist will give her immunoglobulin
Doctor:immediately.
Doctor:This will prevent all events of incompatibility from occuring in the next child.
Doctor:Only when Rh immunoglobulin is not received
Doctor:there are chances of problems with incompatibility during the subsequent pregnancy.
Doctor:Therefore as you see medical problems arising from this marriage can be easily taken care off (prevented).
Doctor:So no reasons to be concerned.
Doctor:Did you follow what I said? Can you summarize our discussion?
User:yes
User:i got it
Doctor:Do you have any more queries?
User:that means before concieving they should seek proper medical advice from gyne and after their first child they should check about rh immunoglobin if childs rh is positive
User:then medical problems can be avoided
Doctor:Complete antenatal check up is a must for all women in all pregnancy.
User:ok
Doctor:Based on the details you provided, i don't see any other need for special extra check ups.
User:thanks a lot doctor
Doctor:And yes, Rh immunoglobulin should be administered without fail
User:your advice is valuable :)
User:okk
Doctor:if the first baby turns out to be Rh positive.
Doctor:If all your questions are answered
Doctor:I wish to know if I can ignore the question you posted on my dashboard.
User:yes yes you can
Doctor:I see you posted the same question before coming to chat here.
User:and if the baby is rh negative
User:then
User:can baby suffer from down syndrome?
Doctor:There are no risks involved if all the baby is Rh negative.
Doctor:Down's syndrome is a different entity altogether.
User:actually in my family my mother has rh positive while my father has rh negative blood group and my sister is a down syndrome child
User:so thats why
Doctor:It is not based on Rh compatibility.
User:we were a bit concerened
User:ok
Doctor:Down syndrome is caused by genetic changes that is not related to blood groups.
Doctor:In your brother's case,
User:ok can that be checked in early stages of pregnancy and is it hereditary?
Doctor:his wife (if she is Rh negative) should receive Rh immunoglobulin whenever she gives birth to Rh positive child.
Doctor:It can be during the first pregnancy or in the subsequent pregnancy.
User:ok
Doctor:As far as Down syndrome is concerned
Doctor:the gynecologist can perform triple marker
Doctor:and other tests during pregnancy
Doctor:which can predict chances of down syndrome.
Doctor:If tests reveal high chances of down syndrome then the couple can take necessary action.
Doctor:Since history of Down syndrome is with your family
Doctor:the risks for down syndrome will be passed on through your brother
Doctor:this has no relation with the girls blood group.
User:ok
User:thanks doctor :)
Doctor:So in short, blood group compatibility is not a ground for choosing marriage bans.
Doctor:Hope I am clear.
Doctor:Do you have any more questions?
User:no thanks doctor
User:this was the only question
Doctor:Thanks for visiting me here. Bye for now.
User:my family ahs misconceptions about this so we thought its better to consult a doctor
