Causes of Miscarriage

A miscarriage is the loss of a pregnancy before 20 weeks, with causes often involving chromosomal abnormalities, maternal health issues, and lifestyle factors.

Overview

Miscarriage is the most common type of pregnancy loss, affecting about 10-20% of known pregnancies. Most occur in the first trimester. While often emotionally devastating, most women who miscarry go on to have successful pregnancies.

Causes

The most common cause is chromosomal abnormalities in the embryo. Other causes include maternal health conditions (diabetes, thyroid disorders, uterine problems), infections, trauma, and lifestyle factors like smoking or excessive alcohol consumption.

Symptoms

Symptoms include vaginal bleeding or spotting, abdominal cramping or pain, and the passing of tissue or fluid from the vagina.

Treatment

Treatment depends on the type of miscarriage. It may involve watchful waiting, medication to help expel the tissue, or a surgical procedure (dilation and curettage).

When to See a Doctor

Contact your healthcare provider immediately if you experience bleeding or cramping during pregnancy.
