Some of them are: Rh factor: Miscarriage can be caused because of the incompatibility of the mother's blood and the blood of the unborn foetus commonly known as Rh factor incompatibility. This type of miscarriage occur when the blood type of mother is Rh negative, and the foetus blood type is Rh positive.
During a pregnancy, Rh antibodies made in a woman's body can cross the placenta and attack fetal blood cells. This can cause a serious type of anemia in the fetus in which red blood cells are destroyed faster than the body can replace them.
ABO incompatibility is one of the most common reasons of bilirubin encephalopathy, and in the uterus this can cause impaired pregnancy and miscarriage (32-34).
Possible Complications
Brain damage due to high levels of bilirubin (kernicterus) Fluid buildup and swelling in the baby (hydrops fetalis) Problems with mental function, movement, hearing, speech, and seizures.
Rh incompatibility usually isn't a problem if it's the mother's first pregnancy. That's because the baby's blood does not normally enter the mother's circulatory system during the pregnancy. During the birth, though, the mother's and baby's blood can mix.
Rh incompatibility isn't harmful to the pregnant mother. However, it can cause mild to serious medical problems for the baby. Doctors treat the condition by injecting the mother with a Rh incompatibility medicine that protects the baby's red blood cells.
The most common cause of Rh incompatibility is exposure from an Rh-negative mother by Rh-positive fetal blood during pregnancy or delivery.
Rh Incompatibility in Pregnancy
Problems can occur when the mother is Rh- and the baby is Rh+. This mismatch in blood type is often referred to as Rh incompatibility. This mismatch doesn't cause any problems for the first pregnancy. But it can lead to problems in later pregnancies.
Treatment for Rh-negative factor
Rh immune globulin injections can be given to keep your body from producing Rh antibodies. If you discover that you have Rh incompatibility problems, you'll need to receive these injections every time you have an Rh-positive baby.
The Rh-negative blood type can pose risks during pregnancy, including increasing the risk of miscarriage or stillbirth in the second or third trimester. Nowadays, women with a negative blood group are preventively given the Rho GAM injection, to reduce the risk involved.
Do I need a RhoGAM shot after a miscarriage or chemical pregnancy? The RhoGAM shot is a good preventative measure to take any time your baby's' blood comes into contact with yours, which can happen if you have a miscarriage or ectopic pregnancy. You won't, however, need a RhoGAM shot after a chemical pregnancy.
The symptoms of antiphospholipid syndrome (APS) are related primarily to abnormal blood clotting, miscarriage, or stillbirth.
If the mother is Rh-negative, her immune system treats Rh-positive fetal cells as if they were a foreign substance. The mother's body makes antibodies against the fetal blood cells. These antibodies may cross back through the placenta into the developing baby. They destroy the baby's circulating red blood cells.
If he's Rh-negative too, the baby has no chance of having Rh-positive blood. Thus, there's no risk of Rh incompatibility. However, if the baby's father is Rh-positive, the baby has a 50 percent or more chance of having Rh-positive blood. As a result, you're at high risk of developing Rh incompatibility.
Severe cases, in which the effects of Rh incompatibility aren't prevented, can result in severe complications. These complications may include: brain damage to the baby, which is known as kernicterus. fluid buildup or swelling in the baby.
For example, if someone's Rh factors are both positive, it is not possible for his or her child to have a negative blood type. Only people with at least one Rh-negative factors will have a negative blood type, which is why the occurrence of Rh-negative blood is less common than Rh-positive blood.
Except in very rare cases, it doesn't matter if you're a different blood group to your baby's dad. What does matter is the rhesus factor, whether you're rhesus-positive (RhD-positive) or rhesus-negative (RhD-negative). People who are RhD-positive have a protein on their red blood cells called D antigen.
A yellow coloring of amniotic fluid. This color may be because of bilirubin. This is a substance that is released when blood cells break down.
Some of them are: Rh factor: Miscarriage can be caused because of the incompatibility of the mother's blood and the blood of the unborn foetus commonly known as Rh factor incompatibility. This type of miscarriage occur when the blood type of mother is Rh negative, and the foetus blood type is Rh positive.
Recurrent early miscarriages (within the first trimester) are most commonly due to genetic or chromosomal problems of the embryo, with 50-80% of spontaneous losses having abnormal chromosomal number. Structural problems of the uterus can also play a role in early miscarriage.
About 50 percent of miscarriages are associated with extra or missing chromosomes. Most often, chromosome problems result from errors that occur by chance as the embryo divides and grows — not problems inherited from the parents.
