1. Spontaneous abortion or miscarriages - is a type of abortion that occur without medical or other intervention. About 25% of all pregnancies result in miscarriages, women older than 35 or younger than 17 years old and couples who have difficulty in achieving pregnancy; and women who have had at least two miscarriages has a higher chance of experiencing miscarriage. About 90% of miscarriages occur during the first trimester (first three months, or 12 weeks of pregnancy). Some cases of miscarriages happen even before a woman realizes that she is pregnant, and she even may not realize that she has aborted.Threatened abortion
2. Threatened abortion is a condition of pregnancy, occurring before the 20th week of gestation, the patient usually experiences vaginal bleeding with or without some cramps, and the cervix is closed. Bed rest is usually the only treatment needed. In a few cases the symptoms disappear and the rest of the pregnancy is normal.
3. Inevitable abortion is when the bleeding continues and becomes heavy, it usually means that the cervix is dilating and the contents of the uterus are being expelled. Pregnant women will experience lower abdominal cramping and bleeding.
4. Complete abortion is when all the contents are expelled. There is no treatment other than rest is usually needed. All of the tissues that came out should be saved for examination by a doctor to make sure that the abortion is complete. The laboratory examination of the saved tissue may determine the cause of abortion.
5. Incomplete abortion is a name given to abortion where the uterus retains part or all of the placenta. Bleeding may occur because part of the placenta may adhere to the uterine wall and the uterus does not contract to seal the large blood vessels that feed the placenta. The usual treatment is a drug that induces labor by stimulating uterine contractions, a surgical procedure called curettage can also be done to remove the remaining material from the uterus, the goal of this treatment is to prevent prolonged bleeding or infection.
6. Missed abortion - is a case in which an intrauterine pregnancy is present but is no longer developing normally. Before widespread use of ultrasonography, the term missed abortion was applied to pregnancies with no uterine growth over a prolonged period of time, typically 6 weeks after its (fetus) death. A missed abortion is usually indicated by the disappearance of the signs of pregnancy except for the continued absence of menstrual periods. Missed abortions are usually treated by induction of labor by dilation (or dilatation) and curettage (D & C).
7. Induced abortion - this type of abortion uses drugs or instruments to stop the normal course of pregnancy. This type of abortion is prohibited by the UAE and Dubai law.
