Question

Why is it that if you are pregnant with the Rh factor but your fetus doesnt have it and you have to get a shot for it why does the baby always die if you miss one?

Answer 1

If you are Rh+,there is no problem,

but if you are Rh-,and fetus is Rh+,your body don't recognize "that Rh+",

and than your body start battle,

the same happened when you have some virus (influenza)!

Answer 2

There are several reasons:

1. Your body doesn't recongize the fetus and thinks that it is a bacteria so it starts to attack it trying to rid your body of this "bacteria".

2. If for some reason you and the baby share blood before delivery (car accident ect.) it can hurt you and the child

3. When you deliver the child you two come in contact with blood and fluids this can hurt you and the child.

4. If you don't get the shot when you go to have another child the chances are very slim, because whether or not it is RH your body attacks it right away even before it has a chance.

5. RH works this way:

* if you or your partner are Rh then you have to get the shot during pregnancy, if you and the Child are RH you only have to get that one shot during the pregancy

* if you or your partner are Rh and your child is born without the rh then you have to get the shot during and after pregnancy and your child must also get it. Hope this answers all

Answer 3

The baby does NOT always die if you do not get the rhogam shot. This shot is a precautionary measure.



If you have a negative blood type, and the baby could possibly have a positive blood type, and your blood comes in contact with the baby's blood (which does not happen under normal circumstances) Your blood would "attack" the positive blood, as it would be seen as a foreign object.



Since most the time, the blood does not mix, it probably won't kill the baby if you don't get it. But IF the blood does come in contact with each other, (like if there is a rupture in the placenta) then your baby could be still born or very anemic.



You get the rhogam shot at 28 weeks normally and then after birth, if the baby's blood type IS positive. If the baby is Negative blood type, there is nothing to worry about. :)



I hope I helped you understand the RH factors a little bit more.

Answer 4

The RH factor (from Reeses Monkey's) is a missing antibody within the mother. For instance if the mother is RH negative and the fetus is RH positive, the mothers system fights against the foreign intruder (RH+). If the mother doesn't get the shot after abortion, misscarriage or giving birth, the mothers system becomes that much stronger against the intruder (RH+) thus any future pregnancies the mothers system has the ability to kill the fetus.

Answer 5

The Rh factor involves a particular antibody in your blood. If the mother is Rh- and the father is Rh+, then the mother's body will attack the embryo (who will most likely have Rh+ blood). This will kill the baby. The shots keep the mother's body from reacting to the baby and attacking it. The letter portion of the blood type doesn't matter in this issue. If the mother is Rh+, then it doesn't matter.

Answer 6

i'm RH unfavourable and all my babies are RH helpful. I had to have the shot with each and each being pregnant. My babies have been born healthful and are actually mum and dad themselves. the only time they provide you the Rhogam shot is while your better half has a good blood type and there's a threat that the infant is additionally helpful or if the daddy's RH ingredient is unknown. The shot prevents your unfavourable blood from contaminating the infant's for the time of start. this might reason miscarriage or fetal dying. If the infant's helpful blood mingles with yours, you ought to get RH affliction. The nurse provide you the shot interior the muscle of your butt or hip. This anti serum is thick and takes a jiffy yet is needed as a results of fact of your blood type. you will additionally settle for a card to hold on your wallet that identifies you as having had the Rhogam shot. With each and each being pregnant after this one you will ought to get yet another dose of Rhogam. you would be positive and could grant a healthful infant as long as you persist with your healthcare expert's instructions.

Answer 7

If the mom's blood is negative, and the babies blood is positive. Without the shot, the mom's immune system can actually attack the baby during birth (as if it were a disease). My mom had the RH factor with all her kids (she's 0 negative, we're all O positive), and had to do the shots.



Actually, she had her first kid just fine without the shots (they weren't invented yet) - quite often the first baby can survive because the first one can get through before the mom's body fully recognized and is ready for a positive blood "foreign invader," by the time the second baby comes, the mom's body is ready for it, and can attack the baby quite quickly.

Answer 8

This is sad, I know someone who lost her baby recently from the RHFactor. Now she has to take the shot each time she is pregnant.

Sometimes the babys blood can leak out into the mother and the mother builds antibodies against it and it starts treating the baby like its a foreign object.

The shot stops the mom from reacting to RH pos. red cells. and attacking the baby.

Answer 9

if you are rh+ your baby will be rh+.



problems arise when you are rh- and the baby is rh+ since you and your baby will share blood through the placenta. there shouldn't be problems with the first rh+ baby, however it's blood will make your blood create anitbodies against the rh so in subsequent pregnancies, an rh+ baby would be miscarried.



i think i got that right. sorry if i screw up my details. i haven't been in school for a year =P

Answer 10

if you are RH NEG and babys Dad is RH POS, then baby could be RH POS. You blood antigens could attack babies positive antigens and recognise them as an invader. The shot prevents damage is your blood mixes. If dad is RH NEG as well, then its a non issue and no shot needed. Baby will be RH neg too

Answer 11

Your body basically doesn't recognize the fetus. Your body attacks the fetus, thinking that it's a danger to you. Although from what I've seen, the baby doesn't always die. Sometimes the baby survives but is born with defects.

Answer 12

I think you're a little confused. You have to get a shot if you have a negative blood type and father of baby is positive or vice versus. The baby could be born either with positive or negative blood type, so you get a shot. See link attached:

Answer 13

the rh factor is referring to your blood type.........say if your blood type is + and your baby's is - then if for some reason something happened and the baby's blood entered your bloodstream your body would fight it off and as a result of that your body would be fighting your child

Answer 14

I am going to copy this straight from the site that I have read about it.. I hope it isn't to long. It is very helpfull however, and tells you everything about it...



Rh Incompatibility



What is Rh incompatibility?

If you are a mother with Rh incompatibility, there is a substance in your baby's red blood cells that is not in your blood cells. This substance is usually called the Rho(D) factor. People who have the Rho(D) factor are Rh positive. People who do not have it are Rh negative. Being Rh negative or positive is something you inherit from your parents, just like you inherit the color of your eyes or hair.



While you are pregnant or delivering the baby, some of the baby's red blood cells may come in contact with your blood. Your body may then make antibodies to the Rho(D) factor. This reaction is called sensitization. The antibodies may cross the placenta and destroy the red blood cells in your baby or any Rh-positive babies you have later. This destruction of red blood cells is called hemolytic disease. This disease can cause serious problems for the baby.



How does it occur?

Rh incompatibility happens only if you are Rh negative and your baby is Rh positive. It does not happen if you are Rh positive and your baby is Rh negative or if both of you are negative or positive.



Usually you are not exposed to a baby's blood until you give birth. This means that your first baby is not likely to be affected by the incompatibility. However, large amounts of the baby's blood often leak into the mother during delivery. Your body might then make antibodies. This can cause problems if you have another Rh-positive baby.



Sometimes the baby's blood may come in contact with your blood before delivery. This might happen, for example, during a miscarriage or abortion or after amniocentesis or other similar tests.



If you are Rh negative and you got Rh-positive blood in a transfusion, you may have developed antibodies that will cause Rh incompatibility.



In most cases, development of antibodies can be prevented.



What are the symptoms?

You will have no symptoms. The baby will have symptoms if he or she develops hemolytic disease. The baby's red blood cells will start to break down, causing anemia. The anemia may cause yellow eyes and skin (jaundice), body swelling, and breathing problems. The baby might die in the womb if too much of the baby's blood is destroyed by the antibodies.



How is it diagnosed?

Blood tests are done to check for the Rho(D) factor to see if you are Rh positive or negative. Blood tests also check for antibodies against the Rho(D) factor. If you are Rh negative, the baby's father should also be tested. If the father's blood is Rh positive, the baby may inherit Rh-positive blood from him. If both you and the father are Rh negative, there will not be a problem because the baby will also be Rh negative.



Some of the tests used to check for hemolytic disease and its effects on the baby are:



amniocentesis (a test of fluid around the baby)

cordocentesis (removing blood from the baby's umbilical cord)

ultrasound scan

nonstress test (a check of the baby's activity and heart rate for a short time)

blood tests

biophysical profile (a check of the baby's movements, heart rate, and brain waves).

How is it treated?

If you have already been sensitized by a previous birth, your baby may have hemolytic disease before birth. Your baby will be carefully checked with ultrasound scans and amniocentesis. These tests will help your provider know what treatment may be needed. For example, the baby may need a blood transfusion in the womb before birth. Sometimes early delivery by cesarean section (C-section) is necessary.



If you have not been sensitized, you will have a shot of Rh-immune globulin (RhoGAM) at about 28 weeks of pregnancy. If you have not delivered the baby within 12 weeks of this first shot, you will have a second shot. You may also be given a shot within 72 hours after a birth (if the baby is Rh positive), miscarriage, abortion, tubal (ectopic) pregnancy, or amniocentesis.



RhoGAM contains antibodies to the Rho(D) factor. The antibodies in the shot will destroy any red blood cells from the baby that are in your blood. Then your body will not make its own antibodies to the Rho(D) factor. If you have the shot at 28 weeks and after delivery, sensitization will be prevented and Rh incompatibility should not be a problem during your next pregnancy.



It is important to have the RhoGAM shot in all cases when the baby's blood could leak into your system. This includes:



during or after all pregnancies, including ectopic pregnancies

after early miscarriages

after chorionic villus sampling or amniocentesis

after external cephalic version (a procedure used to try to change a baby's position in the womb before birth)

after injury to your abdomen.

If you have a threatened miscarriage but do not actually miscarry, you may also need a RhoGAM shot. Discuss this with your health care provider.



How long will the effects last?

Sensitization usually does not happen until after the birth of an Rh-positive baby. Therefore, in most cases Rh incompatibility is not a problem during your first pregnancy and delivery of an Rh-positive baby. However, later pregnancies and deliveries might be affected unless you are treated with RhoGAM.



Once you become sensitized, RhoGAM is not helpful. You will stay sensitized, and the effects are usually worse with each pregnancy.



What can be done to help prevent the problems of Rh incompatibility?

This problem of pregnancy has not happened often since the discovery of RhoGAM. RhoGAM can prevent sensitization. It is given to Rh-negative women right after every delivery, miscarriage, or abortion. It is also given to pregnant Rh-negative women after amniocentesis, after any bleeding episodes, and during the 7th month of pregnancy.

Answer 15

According to my book it's because if your baby is rhesus positive and you are rhesus negative, it's possible for you to form antibodies to your baby's red blood cells.

Hope that helps!
