What percentage of women with bipolar I disorder experience recurrences during pregnancy?

The best understanding of the recurrence of bipolar I disorder during pregnancy indicates that a significant proportion of women with this diagnosis experience mental health challenges during this period. Research shows that approximately 70% of women with bipolar I disorder will experience recurrences of their symptoms when they are pregnant. This rate of recurrence underscores the importance of monitoring and supporting women's mental health throughout their perinatal period, as pregnancy can substantially affect the course of bipolar disorder.

In pregnant individuals with bipolar I disorder, hormonal changes, the physical stress of pregnancy, and the psychosocial adjustments expected during this time can all contribute to symptom exacerbation. It's crucial for healthcare providers to recognize this high recurrence rate and to plan accordingly for the care and management of these patients to reduce risks to both the mother and the developing baby.
