Miscarriage

Miscarriage is the spontaneous loss of a pregnancy before the fetus can survive outside the uterus, most commonly occurring within the first 20 weeks of pregnancy. The majority of miscarriages happen during the first trimester, often before a person even knows they are pregnant.

Miscarriage is relatively common and usually occurs due to factors beyond anyone’s control. While it can be physically and emotionally distressing, many people go on to have healthy pregnancies in the future.

Symptoms

Symptoms of miscarriage can vary in intensity and may develop suddenly or gradually.

Common symptoms include:

• Vaginal bleeding, which may be light spotting or heavy bleeding

• Abdominal or lower back pain

• Cramping similar to menstrual cramps

• Passage of tissue or clots from the vagina

• Sudden decrease in pregnancy symptoms such as nausea or breast tenderness

Not all bleeding during pregnancy leads to miscarriage, but medical evaluation is important when symptoms occur.

Causes

Miscarriage most often occurs because the pregnancy is not developing normally.

Common causes include:

• Chromosomal abnormalities in the fetus

• Problems with embryo implantation

• Infections during pregnancy

• Hormonal imbalances

• Structural abnormalities of the uterus or cervix

• Chronic medical conditions such as diabetes or thyroid disorders

• Severe trauma or injury

In many cases, the exact cause cannot be identified.

Risk Factors

Certain factors increase the likelihood of miscarriage, although it can happen to anyone.

Key risk factors include:

• Advanced maternal age

• Previous miscarriages

• Smoking, alcohol use, or drug use

• Obesity or being underweight

• Poorly controlled chronic illnesses

• Exposure to environmental toxins

• Severe stress or physical trauma

Having one miscarriage does not necessarily increase the risk of future pregnancy loss.

Complications

While most people recover physically after a miscarriage, complications can sometimes occur.

Possible complications include:

• Heavy bleeding or infection

• Incomplete miscarriage requiring medical treatment

• Emotional distress, grief, anxiety, or depression

• Fear or stress related to future pregnancies

Emotional support and follow-up care are important parts of recovery.

Prevention

Not all miscarriages can be prevented, especially those caused by chromosomal abnormalities. However, certain steps may help reduce risk.

Preventive measures include:

• Receiving regular prenatal care

• Managing chronic medical conditions

• Avoiding smoking, alcohol, and illicit drugs

• Maintaining a healthy weight

• Eating a balanced, nutritious diet

• Reducing exposure to harmful substances

• Following medical advice during pregnancy

Early prenatal care and healthy lifestyle choices support the best possible outcomes for pregnancy.
