 This is scientific American sixty seconds science. I'm Ian Chant. Got a minute?

 
Having a kid changes everything from your sleep schedule to the statues of that formerly1 spare room. The stable of bacteria that living in women's gut2 is also transformed when their host becomes pregnant. So finds research in the Journal Cell.
 
The study looked at women in Finland. The women's microbe makeup3 changed dramatically between the first and third trimesters. The array of microbes in the gut went from looking normal in the first three month of a pregnancy4 to resembling what's found in patients suffering from metabolic5 disease in last three. But some of the symptoms of that condition, like weight gain and slower sugar metabolism6 can be beneficial to pregnant women, supporting energy storage that helps a fetus7 develop. Other symptoms, like inflammation, demonstrate that the immune system is functioning properly as a pregnancy comes to term. Scientists don't yet fully8 understand what brings about the changes in gut bacteria. Immune function is a suspect, but factors like hormonal9 signals aren't ruled out. The research suggests that other change to the body, like puberty or old age, could also bring about microbial make-overs.
