Miscarriage, also known as spontaneous abortion, refers to the loss of a pregnancy before the 20th week. It is a relatively common occurrence, affecting about 10-20% of known pregnancies.
Causes of Miscarriage
- Chromosomal Abnormalities: Most miscarriages occur due to genetic problems in the embryo that prevent it from developing normally.
- Maternal Health Factors:
- Hormonal Imbalances: Issues with hormones such as progesterone can affect pregnancy viability.
- Chronic Conditions: Uncontrolled diabetes, thyroid disorders, and autoimmune diseases can increase miscarriage risk.
- Uterine Problems: Conditions like fibroids or structural abnormalities in the uterus.
- Infections: Certain infections, such as rubella, cytomegalovirus (CMV), or bacterial infections, can lead to miscarriage.
- Cervical Issues: Weakness of the cervix (cervical insufficiency) can cause miscarriage, especially in the second trimester.
- Lifestyle Factors:
- Smoking: Increases the risk of miscarriage and pregnancy complications.
- Alcohol and Drug Use: Excessive alcohol consumption and illicit drug use are associated with higher miscarriage rates.
- Environmental Exposures: Exposure to toxins, chemicals, radiation, and certain medications can contribute to miscarriage risk.
- Age: Advanced maternal age (over 35) increases the likelihood of chromosomal abnormalities and miscarriage.
- Physical Trauma: Injury or trauma to the abdomen or pelvic area.
- Unknown Causes: In many cases, the cause of miscarriage remains unidentified despite thorough evaluation.
Symptoms of Miscarriage
- Vaginal Bleeding: Light spotting to heavy bleeding, often accompanied by abdominal pain or cramping.
- Abdominal Pain: Cramping, which may be mild to severe, similar to menstrual cramps.
- Passage of Tissue: Passing blood clots or tissue from the vagina.
- Back Pain: Persistent or severe pain in the lower back.
- Loss of Pregnancy Symptoms: Sudden decrease in pregnancy signs such as breast tenderness or nausea.
Diagnosis
- Physical Examination: A pelvic exam to check for signs of bleeding or abnormalities.
- Ultrasound: Imaging to visualize the fetus and confirm the heartbeat. The absence of fetal heartbeat or developmental abnormalities may indicate miscarriage.
- Blood Tests: Measurement of hCG (human chorionic gonadotropin) levels. A decrease in hCG levels over time may indicate a miscarriage.
- Tissue Analysis: If pregnancy tissue is passed, it may be collected and analyzed to determine the cause, particularly for recurrent miscarriages.
- Genetic Testing: Chromosomal analysis of the fetus or pregnancy tissue to identify genetic abnormalities.
Treatment Options
- Expectant Management: Allowing the miscarriage to progress naturally without medical intervention. This approach may be suitable if there are no signs of infection or excessive bleeding.
- Medication: Use of medications, such as misoprostol, to help expel pregnancy tissue and complete the miscarriage.
- Surgical Procedures:
- Dilation and Curettage (D&C): Surgical removal of pregnancy tissue from the uterus.
- Dilation and Evacuation (D&E): Similar to D&C but performed later in pregnancy if necessary.
Conclusion
Miscarriage is a challenging and often traumatic experience, but it is a relatively common part of the reproductive process. Understanding the potential causes and recognizing the symptoms early can help in seeking timely medical care.
FAQs
Q1: Can I have a healthy pregnancy after a miscarriage?
Yes, many women go on to have healthy pregnancies after a miscarriage. It is advisable to discuss any concerns with your healthcare provider and consider any necessary medical evaluations.

Q3: What are the emotional effects of miscarriage?
Miscarriage can lead to grief, sadness, guilt, anxiety, and depression. It is essential to seek support from loved ones and healthcare professionals to cope with these emotions.
Q4: What should I do if I experience symptoms of miscarriage?
If you have vaginal bleeding, abdominal pain, or other concerning symptoms during pregnancy, contact your healthcare provider immediately for evaluation and guidance.
