| '''Miscarriage''' or ''spontaneous abortion'' is the natural or spontaneous end of a [[pregnancy]] at a stage where the [[embryo]] or the [[fetus]] is incapable of surviving, generally defined in humans at a [[gestation]] of prior to 20 weeks. Miscarriage is the most common complication of early pregnancy.<!--

| In medical contexts, the word "[[abortion]]" refers to any process by which a pregnancy ends with the death and removal or expulsion of the fetus, regardless of whether it's spontaneous or intentionally induced. Many women who have had miscarriages, however, object to the term "abortion" in connection with their experience, as it is generally associated with induced abortions. In recent years there has been discussion in the medical community about avoiding the use of this term in favor of the less ambiguous term "miscarriage."<ref>{{cite journal |author=Hutchon D, Cooper S |title=Terminology for early pregnancy loss must be changed |journal=BMJ |volume=317 |issue=7165 |pages=1081 |year=1998 |pmid=9774309}}<br>

| Labour resulting in live birth before the 37th week of pregnancy is termed "[[premature birth]]," even if the infant dies shortly afterward. Although long-term survival has never been reported for infants born from pregnancy shorter than 21 weeks, infants born as early as the 16th week of pregnancy may cry and live a few minutes or hours.<!--

| A fetus that dies while in the uterus after about the 20th week of pregnancy is termed a "[[stillbirth]]". Premature births or stillbirths are not generally considered miscarriages, though usage of the terms and causes of these events may overlap.

| The clinical presentation of a ''threatened abortion'' describes any bleeding seen during pregnancy prior to viability, that has yet to be assessed further. At investigation it may be found that the fetus remains viable and the pregnancy continues without further problems. It has been suggested that bed rest improves the chances of the pregnancy continuing when a small subchorionic [[hematoma]] has been found on ultrasound scans.<!--

| Alternatively the following terms are used to describe pregnancies that do not continue:
| | ==[[Miscarriage epidemiology and demographics|Epidemiology and Demographics]]== |
| * An [[Anembryonic gestation|empty sac]] is a condition where the gestational sac develops normally, while the embryonal part of the pregnancy is either absent or stops growing very early. Other terms for this condition are ''blighted ovum'' and ''anembryonic pregnancy''.
| |
| * An ''inevitable abortion'' describes where the fetal heart beat is shown to have stopped and the cervix has already dilated open, but the fetus has yet to be expelled. This usually will progress to a complete abortion.
| |
| * A ''complete abortion'' is when all products of conception have been expelled. ''Products of conception'' may include the [[trophoblast]], [[chorionic villi]], [[gestational sac]], [[yolk sac]], and [[fetal pole]] ([[embryo]]); or later in pregnancy the [[fetus]], [[umbilical cord]], [[placenta]], amniotic fluid, and [[amniotic sac|amniotic membrane]].
| |
| * An ''incomplete abortion'' occurs when [[biological tissue|tissue]] has been passed, but some remains ''[[in utero]]''.<!--
| |
| --><ref name="MedlinePlus">{{cite web |author=MedlinePlus | authorlink =MedlinePlus | date = [[2004-10-25]] | url=http://www.nlm.nih.gov/medlineplus/ency/article/000904.htm | title =Abortion - incomplete | work =Medical Encyclopedia | accessdate =2006-05-24}}</ref>
| |
| * A ''missed abortion'' is when the embryo or fetus has died, but a miscarriage has not yet occurred. It is also referred to as ''delayed miscarriage''.
| |
|
| |
|
| The following two terms consider wider complications or implications of a miscarriage:
| | ==[[Miscarriage risk factors|Risk Factors]]== |
| * A ''septic abortion'' occurs when the tissue from a missed or incomplete abortion becomes infected. The infection of the womb carries risk of spreading infection ([[septicaemia]]) and is a grave risk to the life of the woman.
| |
| * ''[[Habitual abortion|Recurrent pregnancy loss]]'' (RPL) or ''recurrent miscarriage'' (medically termed ''habitual abortion'') is the occurrence of 3 consecutive miscarriages. A large majority (85%) of women who have had two miscarriages will conceive and carry normally afterwards, so statistically the occurrence of three abortions at 0.34% is regarded as "habitual".<!--

| Chromosomal abnormalities are found in more than half of embryos miscarried in the first 13 weeks. A pregnancy with a genetic problem has a 95% chance of ending in miscarriage. Most chromosomal problems happen by chance, have nothing to do with the parents, and are unlikely to recur.<!--

| [[PCOS|Polycystic ovary syndrome]] is a risk factor for miscarriage, with 30-50% of pregnancies in women with PCOS being miscarried in the first trimester. Two studies have shown treatment with the drug [[metformin]] to significantly lower the rate of miscarriage in women with PCOS (the metformin-treated groups experienced approximately one-third the miscarriage rates of the control groups).<ref>{{cite journal |author=Jakubowicz DJ, Iuorno MJ, Jakubowicz S, Roberts KA, Nestler JE |title=Effects of metformin on early pregnancy loss in the polycystic ovary syndrome |journal=J.

| |
| | |
| Severe cases of [[hypothyroidism]] increase the risk of miscarriage. The effect of milder cases of hypothyroidism on miscarriage rates has not been established. Certain immune conditions such as [[Autoimmunity|autoimmune disease]]s greatly increase the risk of miscarriage.<ref name="PDR Family Guide 1994" />

| |
| | |
| ==Prevalence==
| |
| Determining the [[prevalence]] of miscarriage is difficult. Many miscarriages happen very early in the pregnancy, before a woman may know she is pregnant. Treatment of women with miscarriage at home means medical statistics on miscarriage miss many cases.<!--

| The prevalence of miscarriage increases considerably with age of the parents. Pregnancies from men younger than twenty-five years are 40% less likely to end in miscarriage than pregnancies from men 25-29 years.

Of women who seek clinical treatment for bleeding during pregnancy, about half will go on to have a miscarriage.<ref name="bmj1997" /> Symptoms other than bleeding are not statistically related to miscarriage.<ref name="risk factors" />
| |
| | |
| Miscarriage may also be detected during an ultrasound exam, or through serial [[human chorionic gonadotropin]] (HCG) testing. Women pregnant from [[assisted reproductive technology|ART]] methods, and women with a history of miscarriage, may be monitored closely and so detect a miscarriage sooner than women without such monitoring.
| |
| | |
| Several medical options exist for managing documented nonviable pregnancies that have not been expelled naturally.
| |
| | |
| ==Management==
| |
| Blood loss during early pregnancy is the most common symptom of both miscarriage and of [[ectopic pregnancy]]. Pain does not strongly correlate with miscarriage, but is a common symptom of ectopic pregnancy.<ref name="risk factors" /> In the case of concerning blood loss, pain, or both, [[Obstetric ultrasonography|transvaginal ultrasound]] is performed. If a viable intrauterine pregnancy is not found with ultrasound, serial [[human chorionic gonadotropin|βHCG]] tests should be performed to rule out ectopic pregnancy, which is a life-threatening situation.<!--
| |
| --><ref name="diagnostic">{{cite journal | author = Yip S, Sahota D, Cheung L, Lam P, Haines C, Chung T | title = Accuracy of clinical diagnostic methods of threatened abortion | journal = Gynecol Obstet Invest | volume = 56 | issue = 1 | pages = 38-42 | year = 2003 | id = PMID 12876423}}</ref><!--

| |
| | |
| If the bleeding is light, making an appointment to see one's doctor is recommended. If bleeding is heavy, there is considerable pain, or there is a fever, then emergency medical attention should be sought.
| |
| | |
| No treatment is necessary for a diagnosis of complete abortion (as long as ectopic pregnancy is ruled out). In cases of an incomplete abortion, empty sac, or missed abortion there are three treatment options:
| |
| *With no treatment ([[watchful waiting]]), most of these cases (65-80%) will pass naturally within two to six weeks.<!--

| |
| *Medical management usually consists of using [[misoprostol]] (a [[prostaglandin]], brand name Cytotec) to encourage completion of the miscarriage. About 95% of cases treated with misoprostol will complete within a few days.<ref name="afp" />
| |
| *Surgical treatment (most commonly [[vacuum aspiration]], sometimes referred to as a D&C or D&E) is the fastest way to complete the miscarriage. It also shortens the duration and heaviness of bleeding, and is the best treatment for physical pain associated with the miscarriage.<ref name="afp" /> In cases of repeated miscarriage or later-term pregnancy loss, D&C is also the best way to obtain tissue samples for [[#Pathology|pathology examination]].
| |
| | |
| ==Pathology==
| |
| When looking for gross or microscopic [[pathology|pathologic]] symptoms of miscarriage, one looks for the products of [[conception]]. Microscopically, these include [[villi]], [[trophoblast]], fetal parts, and background gestational changes in the [[endometrium]]. Genetic tests may also be performed to look for abnormal [[chromosome]] arrangements.
| |
| | |
| ==Psychological aspects==
| |
| Although a woman physically recovers from a miscarriage quickly, psychological recovery for parents in general can take a long time. People differ a lot in this regard: some are 'over it' after a few months, others take more than a year. Still others may feel relief or other less negative emotions.
| |
| | |
| For those who do go through a process of [[grief]], it is often as if the baby had been born but died. How short a time the fetus lived in the womb may not matter for the feeling of loss. From the moment pregnancy is discovered, the parents can start to bond with the unborn child. When the child turns out not to be viable, dreams, fantasies and plans for the future are disturbed roughly.
| |
| | |
| Besides the feeling of loss, a lack of understanding by others is often important. People who have not experienced a miscarriage themselves may find it hard to [[empathy|empathize]] with what has occurred and how upsetting it may be. This may lead to unrealistic expectations of the parents' recovery. The pregnancy and miscarriage are hardly mentioned anymore in conversation, often too because the subject is too painful. This can make the woman feel particularly isolated.
| |
| | |
| Interaction with pregnant women and newborn children is often also painful for parents who have experienced miscarriage. Sometimes this makes interaction with friends, acquaintances and family very difficult.<!--
