But several other factors can also be the culprit, including thyroid disorders, diabetes, immunological disorders, drug abuse, and more.
Up to 70 percent of first trimester miscarriages and 20 percent of second trimester miscarriages occur because of a glitch in the fetus's genes, according to the March of Dimes. During fertilization, the sperm and egg each bring 23 chromosomes together to create perfectly matched pairs. This is a complex process, and a minor glitch can result in a genetic or chromosomal abnormality. While some chromosomal abnormalities are compatible with life such as trisomy 21, the most common type of Down syndrome , other chromosomal disorders are simply not.
Miscarriages caused by chromosomal abnormalities happen more often in women older than The frequency of miscarriage in women below age 20 is around 12 to 15 percent and doubles as the woman approaches age There is nothing that can be done to prevent miscarriage due to a chromosomal abnormality and once a miscarriage has begun there is nothing one can do to stop it.
Whether it be hypothyroidism too low or hyperthyroidism too high , thyroid disorders can lead to problems with infertility or cause recurrent miscarriages. The Malpani Infertility Clinic's website explains that in cases where a woman's thyroid function is low, her body will try to compensate by producing hormones that can actually suppress ovulation.
Conversely, a thyroid that is producing too many hormones can interfere with estrogen's ability to do its job, and it may make the uterus unfavorable for implantation or lead to abnormal uterine bleeding.
