From Sweden – Bipolar women are much more likely to have pregnancy and birth complications, according to a report published in the British Medical Journal. Researchers compared over 800 pregnant women with bipolar disorder to over 300,000 without the condition who were giving birth between 2005 and 2009. 320 of the bipolar patients were treated for their condition, while the remainder were untreated.

Results showed that both treated and untreated mothers were more likely to have a c-section, instrumental delivery, and were also at a 50% increased risk of preterm birth. As well, bipolar women were at raised risk of giving birth to a baby with a small head and one with episodes of low blood sugar levels.
