Miscarriage is a common yet emotionally challenging experience, affecting many couples during their fertility journey. While not all miscarriages can be prevented, understanding their causes and risk factors can empower individuals to take proactive steps toward a healthier life.

What Is a Miscarriage?

A miscarriage refers to the spontaneous loss of a pregnancy before the 20th week. It often occurs during the first trimester and may happen before a woman even realises she is pregnant.

Types of Miscarriage

  • Threatened Miscarriage
    Bleeding occurs, but the cervix remains closed and the pregnancy may continue.
  • Incomplete Miscarriage
    Some pregnancy tissue passes, but medical treatment may be needed to remove the rest.
  • Complete Miscarriage
    All pregnancy tissue is expelled, and the uterus is empty.

What Can Cause a Miscarriage?

While miscarriages can happen for reasons beyond one’s control, several contributing factors are known.

Chromosomal Abnormalities

Most first-trimester miscarriages are caused by irregularities in the embryo’s genetic material.

Maternal Health Conditions

Diseases such as diabetes, thyroid imbalances, or autoimmune disorders increase miscarriage risk.

Uterine and Cervical Abnormalities

Structural problems like a septate uterus or an incompetent cervix can lead to early pregnancy loss.

Infections

Syphilis, parvovirus B19, Zika virus, and cytomegalovirus infections can interfere with foetal development.

Lifestyle Factors

Smoking, alcohol use, substance abuse, and excessive caffeine intake are all known risks.

Maternal Age

Women over 35 have an increased risk due to declining egg quality and hormonal changes.

Previous Miscarriages

Having experienced miscarriage before raises the likelihood of future early pregnancy loss.



How to Prevent a Miscarriage: Proactive Steps

Although not all miscarriages are preventable, the risk can be significantly reduced through a combination of healthy lifestyle choices, proper medical care, and early intervention. Here is a structured guide to lowering your risk and supporting a healthy pregnancy.

Healthy Lifestyle Habits

  • Avoid Smoking
    Eliminating tobacco use improves oxygen supply to the uterus and supports healthy fetal development.
  • Avoid Alcohol and Recreational Drugs
    These substances increase the risk of miscarriage and can harm the developing baby.
  • Maintain a Healthy Weight
    Being underweight or overweight can lead to hormonal imbalances and increase pregnancy complications.
  • Eat a Balanced Diet
    Focus on nutrient-rich foods like fruits, vegetables, whole grains, and lean proteins to support maternal health and fetal growth.
  • Limit Caffeine Intake
    Keep caffeine consumption below 200 mg per day to reduce miscarriage risk.

Prenatal and Medical Care

  • Get Regular Prenatal Check-Ups
    Consistent visits help detect and manage complications early in pregnancy.
  • Follow Medical Advice
    Adhere to your doctor’s recommendations, including managing existing conditions and taking prescribed medications.
  • Take Folic Acid
    Daily folic acid supplementation helps prevent neural tube defects and supports early fetal development.

Infection Prevention

  • Avoid High-Risk Foods
    Avoid raw or undercooked meats, unpasteurised dairy, and foods prone to contamination.
  • Practise Good Hygiene
    Regular handwashing and avoiding contact with sick individuals can reduce your risk of infection.
  • Stay Up to Date with Vaccinations
    Protect yourself and your baby by ensuring you're vaccinated.

Managing Underlying Health Conditions

  • Control Diabetes and High Blood Pressure
    Effective management of these conditions before and during pregnancy reduces miscarriage risk.
  • Treat Thyroid Disorders
    Both overactive and underactive thyroids can interfere with a healthy pregnancy if left unmanaged.

Stress Reduction and Emotional Support

  • Practise Relaxation Techniques
    Incorporate yoga, meditation, or breathing exercises into your daily routine to reduce stress.
  • Maintain a Strong Support System
    Lean on family, friends, or support groups to help manage emotional challenges and reduce anxiety.

What to Do After a Miscarriage: Recovery and Support

Protect yourself and your baby by ensuring you're vaccinated. Understanding the next steps can aid recovery and future planning (Kaushal, 2023).

Medical Care and Follow-Up

  • Seek doctor’s advice
    A follow-up ensures your body is recovering well and rules out complications.

Emotional Support

  • Counselling
    Professional therapy can help manage grief, guilt, and anxiety.
  • Join a Support Group
    Connecting with others who have walked a similar path can gently ease the weight of grief.

Planning Future Pregnancies

  • Timing the Next Attempt
    The World Health Organisation (WHO) recommends waiting at least six months before trying to conceive again, allowing your body and mind time to heal and prepare for a healthy pregnancy.
  • Fertility Support
    Couples with recurrent losses may benefit from fertility assessments and assisted reproduction.
  • Lifestyle Adjustments
    Continue healthy practices even before conceiving again to prepare your body.
