Miscarriage
Overview of Miscarriage
Miscarriage refers to the loss of a pregnancy before the 20th week. It is also called spontaneous abortion. Some women may have a miscarriage before even realizing they are pregnant, while others may experience symptoms such as vaginal bleeding and cramping.
Prevalence of Miscarriage
Globally, miscarriages are fairly common and are the most common cause of pregnancy loss, with 26% of known pregnancies and 10% of clinically recognized pregnancies ending in miscarriage. The real statistics may be much higher because many miscarriages occur at the start of pregnancy.
Signs and Symptoms of Miscarriage
The symptoms of a miscarriage can vary depending on the stage of pregnancy and the individual woman. Some of the most common symptoms of a miscarriage include the following:
- Vaginal bleeding: The most common symptom of a miscarriage is vaginal bleeding, ranging from light spotting to heavy bleeding.
- Cramping: Cramping and abdominal pain can occur during a miscarriage as the uterus contracts to expel the fetal tissue.
- Tissue passing: Women may pass tissue or clots from the vagina during a miscarriage.
- Loss of pregnancy symptoms: Women may notice a sudden loss of pregnancy symptoms, such as nausea or breast tenderness when a miscarriage occurs.
- Back pain: Some women may experience lower back pain during a miscarriage.
It's important to note that some of these symptoms can also occur in healthy pregnancies, and not all women will experience symptoms of a miscarriage.
Types of Miscarriage
There are several types of miscarriage, including:
- Threatened Miscarriage: This occurs when a woman experiences vaginal bleeding, abdominal cramps, and back pain, which can be a sign of an impending miscarriage. However, the pregnancy may continue and develop normally.
- Inevitable Miscarriage: It occurs when the cervix begins to dilate, and the woman experiences vaginal bleeding and abdominal cramps. It’s hard to save pregnancy at this point.
- Incomplete Miscarriage: It occurs when some of the pregnancy tissue gets expelled, but some remain in the uterus. Women may experience vaginal bleeding and abdominal cramps. A medical procedure may remove the remaining tissue.
- Complete Miscarriage: It occurs when all the pregnancy tissue gets expelled from the uterus, and the woman may experience heavy bleeding and abdominal cramps. No further medical intervention is needed.
- Missed Miscarriage: It occurs when the pregnancy has ended, but the body has not yet expelled the tissue. Women may not experience any symptoms, and the loss may come to light during a routine ultrasound.
- Recurrent Miscarriage: It occurs when a woman experiences three or more consecutive miscarriages. It may be due to genetic, hormonal, or immune system factors or other underlying medical conditions.
It's important to note that the experience of miscarriage can be different for every woman and may involve many physical and emotional symptoms.
Causes of Miscarriage
Miscarriages are common and can happen due to many factors. Some of the most common causes of miscarriage include:
- Chromosomal abnormalities: The most common cause of miscarriage is a chromosomal abnormality in the developing fetus. These abnormalities can occur spontaneously or due to other problems with the parents' chromosomes.
- Hormonal imbalances: Hormonal imbalances, such as low progesterone levels, can cause a miscarriage. Progesterone is essential for maintaining a healthy pregnancy, and low levels can lead to a miscarriage.
- Infections: Infections, such as rubella, and toxoplasmosis, and sexually transmitted infections like chlamydia and gonorrhea, can increase the risk of miscarriage.
- Medical conditions: Women with certain medical conditions, such as polycystic ovary syndrome (PCOS), diabetes, and thyroid disorders, are at a higher risk of miscarriage.
- Lifestyle factors: Lifestyle factors, smoking, drinking alcohol, and using drugs can increase the risk of miscarriage.
- Physical trauma: Trauma to the abdomen or uterus, such as a car accident or fall, can cause a miscarriage.
- Maternal age: As women get older, the risk of miscarriage increases. It is because the quality of a woman's eggs decreases as she ages.
Many miscarriages occur for no known reason, and it's difficult to determine the exact cause.
Risk Factors of Miscarriage
Several factors can increase a woman's risk of having a miscarriage. Some of the most common risk factors include:
- Age: Women older than 35 are at a higher risk of miscarriage. The risk increases with age, with women over 40 having the highest.
- Previous miscarriage: Women who have had one or more previous miscarriages are at a higher risk of having another miscarriage.
- Medical conditions: Women with certain medical conditions, such as polycystic ovary syndrome (PCOS), diabetes, and thyroid disorders, are at a higher risk of miscarriage.
- Infections: Infections like rubella, toxoplasmosis, and sexually transmitted diseases like chlamydia and gonorrhea can increase the risk of miscarriage.
- Lifestyle factors: Lifestyle factors, smoking, drinking alcohol, and using drugs can increase the risk of miscarriage.
- Hormonal imbalances: Hormonal imbalances, such as low progesterone levels, can increase the risk of miscarriage.
- Uterine abnormalities: Abnormalities of the uterus, such as fibroids or a septum, can increase the risk of miscarriage.
It's important to note that many miscarriages occur for no known reason, and having one or more risk factors does not necessarily mean a woman will have a miscarriage.
Complications
A miscarriage can be a difficult and emotional experience for a woman and her partner. In addition to the emotional impact, physical complications may occur. Some of the most common complications of a miscarriage include the following:
- Infection: There is a risk of infection after a miscarriage, particularly if there was prolonged bleeding or retained tissue.
- Heavy bleeding: Heavy bleeding can occur during and after a miscarriage, leading to anemia and other complications.
- Need for medical intervention: In some cases, medical intervention may be necessary to complete the miscarriage or prevent complications.
- Emotional distress: A miscarriage can be emotionally distressing, and women may need support to cope with grief and loss.
- Fertility concerns: Depending on the cause of the miscarriage, there may be concerns about future fertility and the ability to carry a pregnancy to term.
Women who have experienced a miscarriage should receive medical care and support to manage complications and address their emotional needs.

Prevention
Unfortunately, in many cases, a miscarriage cannot be prevented. However, there are some steps that women can take to reduce their risk of miscarriage and promote a healthy pregnancy. Here are some tips:
- Maintain a healthy lifestyle: Eating a balanced diet, staying active, getting enough rest, and avoiding alcohol, smoking, and drugs can help reduce the risk of miscarriage.
- Manage medical conditions: Women with certain medical conditions, such as diabetes, thyroid disorders, or PCOS, should work with their healthcare provider to manage their condition before and during pregnancy to reduce the risk of miscarriage.
- Avoid certain infections: Avoiding certain infections, such as rubella, toxoplasmosis, and sexually transmitted infections, can reduce the risk of miscarriage. Women planning to conceive should ensure they are up to date on their vaccinations and take steps to prevent exposure to infections.
- Monitor medications and supplements: Certain medications and supplements can increase the risk of miscarriage. Women should talk to their healthcare provider about any medications or supplements they take or planning to take.
- Seek early prenatal care: Early prenatal care can help identify and manage potential issues that could increase the risk of miscarriage.
Diagnosis
A gynecologist makes a miscarriage diagnosis through several methods, including:
- Ultrasound: An ultrasound can detect the presence of a fetal heartbeat, which is usually detectable around six weeks of pregnancy. If there is no heartbeat or the embryo is not developing as expected, it may indicate a miscarriage.
- Blood tests: Blood tests can measure the levels of pregnancy hormones, such as human chorionic gonadotropin (hCG), progesterone, and estrogen. If these hormone levels are not increasing as expected, it may indicate a miscarriage.
- Physical exam: A healthcare provider may perform a pelvic exam to check for changes in the cervix that may indicate a miscarriage.
- Tissue analysis: If a woman experiences heavy bleeding or passes tissue, the tissue may be sent to a laboratory for analysis to confirm a miscarriage.
It is important to seek medical attention if you suspect you may be experiencing a miscarriage. Your healthcare provider can help diagnose the miscarriage and provide appropriate care and support.
Treatment of Miscarriage | When to Consult a Doctor
The treatment for a miscarriage depends on several factors, including the stage of pregnancy and the woman's overall health. Treatment options include:
- Expectant management: If the miscarriage occurs early in pregnancy and the woman is not experiencing any symptoms, her gynecologist may recommend waiting for the miscarriage to occur naturally.
- Medications: Medications like misoprostol or mifepristone, may help induce miscarriage and reduce the risk of infection.
- Surgery: In some cases, a surgical procedure called dilation and curettage (D&C) may be necessary to remove any remaining tissue from the uterus.
- Emotional support: Miscarriage can be emotionally challenging, and women may benefit from counseling or support groups to help them cope with their feelings.
It is essential for women to follow their healthcare provider's recommendations for treatment and to take care of themselves physically and emotionally during this time. It is also crucial to discuss any concerns or questions with your gynecologist.
