Did Chromosomes Cause Your Loss?

This is what most women hear after miscarriage. Doctors treat by soothing worries, suggesting that no real medical problem exists. They’re often wrong. To provide meaningful treatment, doctors should test for the cause of miscarriage.

Chromosome abnormalities are the most common cause of loss, accounting for at least half of all losses. But every woman does not have a 50% chance that her loss was caused by these irregularities. The odds change according to the mother’s age, and the pregnancy’s time of demise.

Mother’s age
Older women face a higher risk of fetal chromosome abnormalities than younger women. In a study of women who had miscarried, 36% of 24-year-old patients had fetal chromosome abnormalities, but for 35-year-old patients, the number increased to 68%.

The pregnancy’s time of demise
Earlier losses are more likely to have chromosome abnormalities than later losses.
