What it is
Your microbiome is the trillions of bacteria living in your gut, mouth, skin, and vagina. In pregnancy it changes on its own. Digestion also slows, so constipation and bloating are common. Your baby picks up a first set of bacteria at birth, from the birth canal, your skin, and your milk.
What's typical
Constipation touches up to 4 in 10 pregnant mothers. Fiber needs go up, and most mothers get less than half of what guidelines suggest. Probiotics are considered safe in pregnancy. The research on benefit is mixed and depends on the strain.
What's known
Studies link a diverse gut before and during pregnancy with lower rates of gestational diabetes and preeclampsia, though cause is not proven. Reviews of probiotic trials find some benefit for constipation and maybe for eczema in the baby. Korean kimchi, German sauerkraut, and Indian yogurt put fermented food on the table long before the word microbiome existed.
What helps
- Add one fiber food to each meal: beans, oats, berries, vegetables, chia or flax.
- Eat fermented foods you already like: yogurt, kefir, sauerkraut, kimchi, miso. A spoonful counts.
- Drink water with the fiber, or it can make constipation worse.
When to call someone
- Nowsevere belly pain, vomiting blood, or black or bloody stool.
- Todayno bowel movement for a week, or diarrhea for more than two days with signs of dehydration.
- At your next visityou want to try a probiotic, you have IBS or Crohn's, or constipation is taking over your life.
