Not to be pedantic, but the article refers to microbiology in the gut, not the stomach. You are unlikely to find bacteria in the stomach unless it is Helicobacter pylori.

Interesting! I wonder if any of this had to do with gastric motility--digestion slows way down in pregnancy...leaving food in the gastrointestinal tract for longer which may be beneficial for the bacteria seen in metabolic disorder (difference in nutrient availability and pH can result in different growth rates for one bacteria vs. another)

well, it is a 7 lb. parasite growing in your body. it makes sense your immune system is going to have something to say about it.

charles it isn't that you always say "mean" things about women, it's that you weirdly focus on the negative (or the sexual).
"diseased" guts of women = negative. it somehow fits your pattern.
but your clip IS interesting. the lengths the pregnant body goes to to keep on accepting that foreign fetus...by beating that immune system into submission.
however i wonder if the effect is only immune system related. digestion gets all the heck messed up during pregnancy, and it isn't just due to microbes.

Pregnant women are smug
And there's something wrong
with their stomach bug.....

I wonder if this relates to the strange phenomenon of gestational diabetes.

@1: thank you for clarifying. That was bothering me, too.
Also, it could have "something" to do with the immune system, but it could also have something to do with the change in carbohydrates in the gut during pregnancy, a known phenomenon. Microbes latch on to the intestinal mucosa by grabbing onto carbohydrate chains. Pregnancy is known to alter the production of those carbohydrates, which in turn changes the makeup of the gut microbiota. There's evidence this same change is happening throughout a woman's regular hormone cycles, not just during pregnancy. While all this affects infection and disease, it's not really "immunology" in the strict sense.
