Spontaneous abortion.
Spontaneous loss of a pregnancy before 24 weeks of gestation.
A situation in which an unborn baby leaves the uterus before the end of the pregnancy, especially during the first seven months of pregnancy.
The loss of a fetus before the 28th week of gestation; an involuntary termination of a pregnancy, often medically called a spontaneous abortion. (Death of a fetus at a later stage is called a stillbirth.) Miscarriage is extremely common, affecting at least 10 percent of all pregnancies, and perhaps as many as 30 percent, since many of these spontaneous abortions occur in the first 10 weeks, often without the woman even being aware that she is pregnant.
Spontaneous abortion; loss of a pregnancy before the fetus is developed enough to survive outside the uterus, or before approximately 20 weeks of gestation. Fifteen to 20 percent of all pregnancies result in miscarriage. It is more common in women older than 35 years of age and in pregnancies with more than one fetus. A miscarriage often resembles an especially heavy menstrual period.
The spontaneous (without outside efforts) termination of a pregnancy before the middle of the pregnancy, the middle of the second trimester.
Lay term for termination of pregnancy at any time before the fetus has attained the potential for extrauterine viability.
The expulsion of a dead zygote, blastocyst, embryo, or fetus from the uterus.
The loss of a pregnancy or expulsion of a fetus before it has developed sufficiently to survive outside the mother’s body. It is also called a spontaneous abortion or natural abortion.
The termination of a pregnancy prior to the 24th week or before the point of viability (the ability to survive independently outside the uterus without artificial assistance) is referred to as a miscarriage. Medically, this is termed “spontaneous abortion.” Most miscarriages happen during the initial 12 weeks of pregnancy and can sometimes be misconstrued as a delayed menstrual cycle.
Miscarriages can transpire due to chromosomal irregularities or developmental flaws in the fetus, as well as from serious maternal illness, exposure to harmful substances, or maternal autoimmune disorders. Instances of miscarriages happening in later stages of pregnancy might be attributed to genetic disorders, cervical insufficiency, uterine abnormalities, or the presence of sizable noncancerous uterine fibroids.
The indications involve substantial vaginal bleeding coupled with cramps. A minor amount of blood loss combined with intense pain can signify either a potential miscarriage or an ectopic pregnancy (the embryo developing outside the uterus).
Medically, miscarriages are categorized as various forms of abortion. A threatened abortion involves a living fetus within the uterus. An inevitable abortion signifies the demise of the fetus, which is subsequently expelled from the uterus. In the case of a missed abortion, the fetus has passed away but remains within the uterus.
To evaluate the pregnancy, a pelvic examination and ultrasound scan might be conducted. If all uterine contents have been expelled, additional treatment might not be needed. However, if remnants remain, a dilation and curettage (D and C) procedure could be performed. For cases of missed abortion, a D and C or induction of labor is determined based on the pregnancy’s duration. Rh-negative women receive anti-D (Rho) immunoglobulin to avert complications associated with Rhesus incompatibility in subsequent pregnancies.
