Experiencing Recurrent Pregnancy Loss: Here is What Could Be Causing It

Around 15% of pregnancies end in miscarriage, yet for so many couples in Mountain View, California, who experience it, the cause is a mystery. It’s thus essential to explore some possible causes of recurrent pregnancy loss (RPL), including chromosomal abnormalities, uterine abnormalities, and hormonal imbalances. If you have experienced multiple miscarriages, it is essential to consult with your specialist in Recurrent Pregnancy Loss in Mountain View to determine the root cause and seek treatment.

Thyroid Problems

The thyroid gland, located in the front of your neck, produces many hormones. Among them are T3 and T4, which regulate your metabolic rate. When you have an underactive thyroid (hypothyroidism), you may gain weight quickly despite eating normally because your metabolism isn’t working efficiently.

Similarly, your metabolism may become less efficient when overactive thyroid (hyperthyroidism). Some women with hyperthyroidism are diagnosed with Graves’ disease, also known as thyrotoxicosis. The symptoms of hyperthyroidism can include fatigue, weight loss despite regular eating habits, irritability, and muscle weakness. 

If you have underlying thyroid problems, it can affect your fertility. Women with an underactive thyroid may not ovulate regularly and thus struggle to conceive, while those with hyperthyroidism can trigger early menopause. It is estimated that 5%-15% of women who seek infertility treatment will have a thyroid disorder.

Uterine Problems

Endometriosis is one endometrial problem that may cause repeated miscarriages. It occurs when the type of tissue that forms the lining of your uterus (endometrium) grows in other areas, like your ovaries or fallopian tubes. The displaced tissue can interfere with normal reproductive function and implantation, leading to miscarriage.

Another possible cause of RPL is Asherman’s syndrome, caused by scar tissue growth within your uterus. This can impede implantation and reduce the size and shape of your uterine cavity, thus making it difficult for a fertilized egg to develop appropriately.

Genetic Causes

Chromosomal abnormalities cause an estimated 50%-75% of miscarriages, either from an inherited anomaly or a random occurrence. Chromosomes contain the genetic material that determines your unique physical and mental attributes, including sex and eye color. They also play a role in deciding whether you will experience miscarriage or not.

When genetic abnormalities are involved, you can have a baby later in life when the effects of these abnormalities have been diminished through natural selection. Sometimes, no cause can be identified, which is estimated to occur in up to 50% of RPL cases.

Blood Clotting Disorders

Hormonal imbalances are not the only potential cause of repeated miscarriages. Thrombophilia is a blood disorder caused by clotting problems and can lead to clots in your uterus, cervix, or placenta. These clots impede normal reproductive function and implantation and can thus cause miscarriage.

Perinatal Infections

Infections such as cytomegalovirus (CMV), human immunodeficiency virus (HIV), and parvovirus B19 can cause miscarriage when passed from a pregnant woman to her fetus. CMV is the most common congenital infection and can cause serious side effects in newborns, such as mental retardation and deafness.

If you have experienced multiple miscarriages, it is essential to consult with your doctor to determine the root cause and seek treatment. Thyroid problems, uterine problems, genetic causes, blood clotting disorders, and perinatal infections are the most common reasons for recurrent pregnancy loss. Don’t despair if you haven’t been able to conceive yet, as fertility specialists can help.
