The majority of spontaneous abortions are caused by chromosomal abnormalities or excessive exposure to chemical substances in the life of the patient, as well as some kind of severe stimulation of the pregnant woman, especially excessive mental and psychological stress, which can lead to the phenomenon of abortion in pregnant women. In some cases, miscarriage may also occur due to a significant decrease in hormone secretion in the body. Some spontaneous miscarriages are complete, called complete miscarriages, and most patients do not need treatment. However, some patients have incomplete abortions, which may result in residual abortions, causing hemorrhage, hemorrhagic shock and other disorders, which require timely treatment in the Obstetrics and Gynecology Department of the local public hospital for removal of the uterus.
