Recurrent Pregnancy Loss
Pregnancy loss can occur at various times in gestation. Often it occurs as early as a few days after the missed period. Other times miscarriage does not occur until after the pregnancy can be visualized by ultrasound or even after the fetal heart beat can be heard.
Pregnancy Loss Support
For further support through this difficult time, Virtua hospital offers families who have experience the loss of a pregnancy or infant to join their Perinatal Bereavement Program.
Causes of a Miscarriage
It is important to know that rarely does an inadvertent action on the part of the woman causes the loss of a pregnancy. However, it is easy for a woman to falsely blame herself for the miscarriage. Learn some of the more common causes of a miscarriage below.
• Having a medical illness such as diabetes or lupus can increase a woman’s risk for miscarriage
• Studies indicate that approximately 70% of pregnancy losses are due to chromosomal imbalances in the fetus
•The presence of a fibroid, septum or scar tissue inside the uterus can interfere with the proper fetal growth
•Cervical incompetence can cause a miscarriage, due to the cervix’s lack of strength to hold the pregnancy in place
•A thyroid gland that is either under-active or over-active can cause miscarriage
Recurrent Pregnancy Loss Treatment
There are treatment options that can help women who have experienced prior pregnancy losses. It is important to be evaluated by a specialist in Reproductive Endocrinology if you have had two or more miscarriages, or if it has been determined that a pregnancy loss has been caused by an issue such as a cervical or uterine abnormality. Please contact us today for more information on our treatment options.
• Blood tests can be done to determine if there is a thyroid gland disorder, and a supplemental thyroid hormone medication will help the under or over-active thyroid.
•Abnormalities requiring surgery such as fibroids, septum or scar tissues or can be removed by a procedure called a hysteroscopy (similar to a D&C), thus allowing the woman to go on and have a normal pregnancy in the future.
•The use of a cervical stitch called a cerclage is sometimes used to decrease the risk of pregnancy loss in women who have experienced cervical incompetence.
•Another simple blood test called anticardiolipin antibody with anticoagulants (ACA) assay that should be offered is to check for certain antibodies that can lead to the clotting of blood vessels to the placenta which nourishes the fetus, which is Antiphospholipid Syndrome (APS).
Other Factors to Consider with Recurrent Pregnancy Loss
Checking the chromosomes of the woman and her partner is another test that is frequently offered to patients who have had recurrent miscarriages. It can detect cases where the man or woman have chromosomes that increase the chance for the fetus to inherit an unbalanced set of chromosomes – a situation which is usually not compatible with continued fetal growth.
Some woman do not reliably ovulate (release an egg) each month. These women often have PCOS (Polycystic Ovarian Syndrome). When these women do ovulate, the egg is often not fully ripened – leading to an embryo that is more likely to stop growing. The adequacy of ovulation can be tested by either a blood test for progesterone a week after ovulation or by a biopsy of the endometrium (the lining of the uterus).
In at least half of the couples who undergo an evaluation for recurrent miscarriages, there is no identifiable cause. The good news is that these couples have an excellent chance for having a normal baby with their next pregnancy. Their chance for a normal pregnancy is very similar to that of a couple who has never had a miscarriage. So our advice for such couples is to try again and not to lose hope. Sometimes it is helpful for the couple to seek counseling to help cope with the grief they are experiencing. It is safe to try to conceive again 2 or 3 months after a miscarriage (sometimes even sooner if the loss was very early). Future pregnancies can be monitored closely with hormone assays and early sonograms. If another miscarriage occurs, we recommend that any miscarriage tissue (passed spontaneously or obtained at the time of a D&C) be examined for a chromosomal imbalance. A positive finding of an imbalance will give the couple the answer they are often looking for, “What went wrong this time?”
What else can a woman do to help avoid another miscarriage? She should avoid smoking cigarettes and limit her caffeine intake to no more than 2 caffeinated beverages per day. Even before a woman wants to try to conceive she should take folate (a vitamin) which is critical for the early growth of the embryo. One milligram should be taken every day. Your physician will tell you if you need other special medication like progesterone or baby aspirin. Most treatment is individualized depending on the specifics of the case.
Though miscarriage can be emotional devastating, it is a common occurrence, and there is a very high chance that the next pregnancy will be normal. Your concerns can often be alleviated by asking your doctor. Therapy is sometimes recommended and is usually successful.
