what causes miscarriage for the first time? In the first instance Did you know that there are different types of a miscarriage?
To begin with lets look at the earliest type of miscarriage.
Bio chemical pregnancy is the earliest type of infant miscarriage.
It can occur before a woman even learns that she is pregnant. Besides a chemical pregnancy, an egg is fertilized, but dies shortly after implantation in the mothers womb so a heartbeat is never identified. What causes a miscarriage at this stage ? Its usually due to the developing egg. In general 1 in 4 pregnancies will end in a miscarriage.
Next is a threatened miscarriage Bleeding and cramping in pregnancy that does not result in a miscarriage. The pregnancy carries on until the birth of the baby.
Missed miscarriage (delayed or silent) the pregnancy has stopped developing but is still inside the mothers womb. The mum can go on to naturally expel the baby and the tissue. sometimes a d and c is offered. usually performed to prevent infections. This happens in a hospital as an operation.
Incomplete miscarriage: most of the contents of the pregnancy in the womb as naturally miscarried but there is still some tissue left inside, if not removed can cause infection to the mother.
Complete miscarriage: All of the pregnancy tissue including the growing baby has died and has been passed through the vagina .resulting in an empty uterus.
Recurrent miscarriage: When a woman loses three or more pregnancies before 23 completed weeks
what causes miscarriage before 12 weeks pregnant
In the event you have a miscarriage before 12 weeks pregnant it is usually due to the developing fetus.
what causes miscarriage at 18-20 weeks gestation a late miscarriage
Sadly for some women do experience many losses of their baby after 12 weeks. The baby may be born too premature to survive. Cervical incompetency or very early premature labour can be the cause of this late miscarriage.
Thus the cervix begins to dilate before the pregnancy has reached full term. Cervical incompetence may cause miscarriage or preterm birth during the second and third trimesters. By the way Cervical incompetence accounts for about 15 to 20 percent of all pregnancy losses during the second trimester.
when Infections cause miscarriages
In fact Some viral and bacterial infections increase the risk of a late miscarriage. Research found in some instances bacterial vaginosis infection occurred in pregnancy to first and second trimester miscarriages. S.T.D chlamydia might increase miscarriages. Along with Listeria and Salmonella infections by food related infections can also be what causes miscarriages.
Can Abdominal trauma be reason what causes miscarriage?
Yes , this may be in the form of a physical assault, a motor traffic accident, a domestic accident or an accident at work. A direct penetrating trauma to the uterus reduces the prospects for the fetus quite substantially.
Subsequently When a pregnant woman is injured it can result i a miscarriage.Especially if it is somewhere around the abdomen or pelvis, the ensuing anxiety becomes two-pronged. “Am I alright and is my baby alright?” This concern is readily understandable and explainable.
The natural maternal instinct is for the preservation of her child. However, it is also true that nature makes pregnancies fairly safe from considerable trauma. Furthermore even when this is directly inflicted on the abdomen or pelvis. Resulting in a fetal demise simply because of its severity.
As a result this may be in the form of direct trauma to the fetus itself. By the way perforation of the womb, can resultant in severe internal bleeding. Miscarriage or premature labour are not common consequences, even of a major trauma.
miscarriages due to birth defects and genetic problems
In this case Congenital birth defects, such as heart malformations in the baby can be the cause of a miscarriage placenta previa. Nemaline myopathy. Aeortic stenosis .CHD.GBS. or Velementous insertion.
beyond this If you have lost one baby to any of the above conditions consult your consultant for future pregnancies. You may need to be closely monitored have regular scans to pick up any problems early on. In conditions Such as an Incompetent cervix you can have a stitch put into your cervix to enable you to carry baby to full term or near to. Next the stitch is removed just before you give birth.
