Miscarriage: A Comprehensive Guide


Miscarriage is the loss of a pregnancy before the 20th week of gestation. It is a common experience, affecting up to 20% of pregnancies. Most miscarriages occur during the first trimester (before 12 weeks of pregnancy).

Causes of Miscarriage

The causes of miscarriage are often unknown. However, certain factors can increase the risk of miscarriage, including:

  • Chromosomal abnormalities: These are errors in the number or structure of chromosomes in the fertilized egg. Chromosomal abnormalities are the most common cause of miscarriage in the first trimester.
  • Hormonal imbalances: Progesterone is a hormone that helps to maintain a pregnancy. Low levels of progesterone can lead to miscarriage.
  • Uterine abnormalities: Uterine abnormalities, such as fibroids or polyps, can interfere with the implantation or growth of the embryo.
  • Immune disorders: Some immune disorders can attack the pregnancy, leading to miscarriage.
  • Infections: Infections, such as rubella or toxoplasmosis, can cause miscarriage.
  • Maternal age: The risk of miscarriage increases with maternal age, especially after age 35.
  • Environmental factors: Exposure to certain environmental toxins, such as lead or mercury, can increase the risk of miscarriage.
  • Lifestyle factors: Smoking, drinking alcohol, and using illegal drugs can increase the risk of miscarriage.

Symptoms of Miscarriage

The symptoms of miscarriage can vary depending on the stage of the pregnancy.

Early miscarriage (before 12 weeks):

  • Vaginal bleeding or spotting
  • Cramping or abdominal pain
  • Loss of pregnancy symptoms, such as nausea or breast tenderness

Late miscarriage (12-20 weeks):

  • Heavy vaginal bleeding or clots
  • Severe abdominal pain
  • Back pain
  • Fever or chills

Diagnosis of Miscarriage

Miscarriage is diagnosed based on a combination of symptoms and a physical examination. Your doctor may perform a pelvic exam to check for cervical dilation or effacement. They may also order an ultrasound to confirm the miscarriage.

Treatment for Miscarriage

There is no specific treatment for miscarriage. However, your doctor may recommend:

  • Pain medication to relieve discomfort
  • Anti-inflammatory drugs to reduce swelling
  • Hormonal therapy to stop bleeding
  • Surgery to remove any retained tissue

Emotional Impact of Miscarriage

Miscarriage can be a devastating experience. It can lead to feelings of grief, loss, and sadness. It is important to allow yourself time to grieve and to seek support from family and friends.

Preventing Miscarriage

There is no sure way to prevent miscarriage. However, there are certain things you can do to reduce the risk, including:

  • Eating a healthy diet
  • Getting regular exercise
  • Maintaining a healthy weight
  • Avoiding smoking, alcohol, and illegal drugs
  • Getting vaccinated against rubella and toxoplasmosis
  • Managing chronic health conditions
  • Seeing a doctor regularly for prenatal care

When to Call a Doctor

Call your doctor immediately if you experience any symptoms of miscarriage, such as vaginal bleeding or severe abdominal pain.


Miscarriage is a common experience, but it can be a devastating one. It is important to understand the causes, symptoms, and treatment options for miscarriage. If you experience a miscarriage, it is important to allow yourself time to grieve and to seek support from family and friends.
