Birth of baby girl may mean worsening of asthma among pregnant womenPregnant women carrying a girl child and suffering from asthma are at an increased risk of experiencing worsening asthma symptoms than pregnant women carrying a boy child, as per a study presented at the American Thoracic Society International Conference in Orlando on May 25.

Lead researcher Peter G. Gibson, M.D., said that while the reason behind this difference is still unknown, it may be because the female fetus can produce a substance in response to asthmatic mother’s airway inflammation leading to worsening of asthma.

Dr. Gibson, Professor in the Department of Respiratory and Sleep Medicine at Hunter Medical Research Institute at John Hunter Hospital in Newcastle, Australia, remarked that the good news is that asthma among pregnant women can be controlled with asthma treatment.
