There are many possible causes of miscarriage, and in many cases the underlying cause is unknown. Some known causes include:
-Chromosomal abnormalities: Most miscarriages are caused by abnormal chromosomes in the embryo. This can be due to a problem with the egg, sperm, or the fertilization process itself.
-Hormonal problems: Hormonal imbalances can interfere with the development of the embryo, and may be a contributing factor in some cases of miscarriage.
-Infection: Infections such as toxoplasmosis or cytomegalovirus can cause miscarriage.
-Physical problems: Physical problems with the uterus or cervix can occasionally lead to miscarriage.
-Exposure to toxins: Exposure to certain toxins, such as lead or mercury, can increase the risk of miscarrying.
-Maternal health problems: Certain health conditions, such as diabetes or autoimmune diseases, can increase the risk of miscarrying.
-Stress: While the exact role of stress in miscarriage is not clear, it is thought to be a contributing factor in some cases.
