Miscarriage refers to the loss of a pregnancy before the 20th week. It is a relatively common occurrence, affecting around 10-20% of known pregnancies. The emotional toll of a miscarriage can be profound, affecting both partners and their families. Understanding the causes, treatment options, and prevention strategies is essential for both healthcare professionals and individuals hoping to conceive. This blog explores the major factors behind miscarriage, treatments, and ways to minimize the risk of its occurrence. Scroll till the end to read what our expert gynaecologist in Patiala has to share regarding miscarriages and miscarriage prevention tips.
Causes of Miscarriage
Several factors contribute to miscarriage, which can be broadly classified into genetic, maternal, lifestyle, and environmental factors. Here is a list of major causes of miscarriage:
1. Genetic Abnormalities
Genetic causes are the most common reason for miscarriage, especially in the first 3 months. Chromosomal abnormalities occur when the fetus receives too many or too few chromosomes, preventing normal development. Conditions like trisomy an extra chromosome or monosomy missing a chromosome often result in pregnancy loss. These abnormalities are usually random and not linked to parental genetics. However, some parents carry genetic conditions, such as balanced translocations, which may increase their risk of miscarriage.
2. Maternal Health Conditions
Several maternal health conditions can predispose a woman to miscarriage:
Hormonal Imbalances: Conditions like polycystic ovary syndrome (PCOS) or thyroid disorders (both hyperthyroidism and hypothyroidism) can lead to pregnancy loss due to disrupted hormone levels. Other health conditions may also include:
-
Autoimmune Disorders
-
Uncontrolled Chronic Diseases
-
Infections
3. Lifestyle Factors
Lifestyle choices and habits can also significantly impact pregnancy outcomes:
-
Smoking: Tobacco use is a well-established risk factor for miscarriage. The chemicals in cigarettes can impair the placenta and restrict oxygen supply to the fetus, leading to pregnancy loss.
-
Alcohol Consumption: Alcohol interferes with fetal development and can cause a range of problems, from miscarriage to fetal alcohol syndrome. The risk of miscarriage increases with the amount of alcohol consumed.
-
Drug Use: Illicit drugs such as cocaine, heroin, and marijuana, as well as certain prescription medications taken without medical supervision, can negatively affect pregnancy outcomes.
-
Caffeine: Excessive caffeine consumption of more than 200 mg per day has been linked to an increased risk of miscarriage, though the exact relationship remains a topic of debate.
4. Environmental and Occupational Hazards
Exposure to harmful environmental agents, such as radiation, toxic chemicals, and heavy metals, can increase the risk of miscarriage. Women working in certain industries, such as agriculture or manufacturing, may be more susceptible to these risks. Prolonged exposure to secondhand smoke, air pollution, and certain cleaning agents may also contribute to miscarriage.
5. Anatomical Abnormalities
Structural abnormalities in the uterus, such as uterine fibroids, adhesions, or an abnormally shaped uterus, can impede the successful implantation and growth of the embryo. Cervical insufficiency, where the cervix opens prematurely, is another anatomical cause of miscarriage.
6. Advanced Maternal Age
The risk of miscarriage increases significantly with age, particularly after age 35. This is largely due to the increased likelihood of chromosomal abnormalities in the eggs. Women over 40 have a 50% chance of miscarriage, while women under 35 have about a 15-20% chance.

Treatment of Miscarriage
Treatment for miscarriage is tailored based on the stage of pregnancy and the woman’s overall health. The primary goal is to ensure the complete removal of pregnancy tissue and manage any complications.
1. Expectant Management
In some cases, no immediate intervention is necessary. The body may expel the fetal tissue naturally over time. This approach is called expectant management. It is often considered when the miscarriage occurs early in pregnancy and the woman is in good health. However, close monitoring is essential to prevent complications like infection or incomplete miscarriage.
2. Medical Management
Medications like misoprostol may be prescribed to speed up the process of expelling fetal tissue. This method is effective for early miscarriages and can be done at home under a doctor’s supervision. Pain management is crucial during this process, as cramping can be severe.
3. Surgical Management
If the miscarriage is incomplete, or if there are signs of infection, surgical intervention may be necessary. Procedures like dilation and curettage (D&C) involve removing the pregnancy tissue from the uterus. This is typically performed under anaesthesia and carries a low risk of complications. Surgical management is also preferred in cases of later-term miscarriage.
4. Emotional and Psychological Support
Miscarriage can have a significant emotional impact, and grief, anxiety, and depression are common reactions. Counseling or therapy, as well as support groups, can be helpful for both women and their partners. Healthcare providers should offer compassionate care and support during this difficult time.

Prevention Strategies
While not all miscarriages can be prevented, certain strategies can reduce the risk of occurrence. Miscarriage prevention measures target both modifiable and non-modifiable factors.
1. Preconception Care
Women planning to conceive should schedule a preconception visit with their healthcare provider. During this visit, potential risk factors such as chronic health conditions, medications, and lifestyle habits can be evaluated and addressed. Vaccination against infections like rubella can also help prevent miscarriage.
2. Lifestyle Modifications
-
Quit Smoking and Alcohol: Women who smoke or consume alcohol should quit before becoming pregnant. This greatly reduces the risk of miscarriage and other pregnancy complications.
-
Limit Caffeine: Limiting caffeine intake to 200 mg or less per day can help reduce the risk of miscarriage.
-
Exercise Moderately: Regular, moderate exercise is beneficial, but strenuous or high-impact activities should be avoided, especially in high-risk pregnancies.
3. Managing Chronic Conditions
Conditions such as diabetes, hypertension, and thyroid disorders should be managed carefully. Blood sugar levels, blood pressure, and thyroid hormone levels should be kept within normal ranges to minimize the risk of complications. Regular checkups and medication adjustments may be necessary.
4. Early Prenatal Care
Regular prenatal visits are essential to monitor the health of both mother and baby. Early detection of potential issues, such as infections or cervical insufficiency, allows for timely intervention and reduces the risk of miscarriage.
5. Genetic Counseling
Couples with a history of recurrent miscarriages or known genetic disorders should consider genetic counselling. Tests such as karyotyping can help identify chromosomal abnormalities in the parents. In some cases, assisted reproductive technologies like in-vitro fertilization (IVF) with preimplantation genetic testing (PGT) can be considered to select healthy embryos for implantation.
6. Preventing Infections
Practising good hygiene, avoiding unpasteurized foods, and staying away from individuals with infectious illnesses can help reduce the risk of contracting infections that could lead to miscarriage.
Conclusion
Miscarriage is a complex and multifactorial condition, with causes ranging from genetic abnormalities to lifestyle and environmental factors. While some risk factors are beyond control, many can be managed through proper healthcare, lifestyle modifications, and early intervention. With the appropriate treatment and support, many women can go on to have successful pregnancies after miscarriage. Ongoing research and improvements in reproductive medicine continue to enhance the understanding of miscarriage, offering hope for more effective prevention and treatment strategies in the future.
