Just got handed a prescription for antibiotics, and part of you is already bracing for the stomach trouble that tends to follow. Fair instinct. Antibiotics can't tell the difference between the bacteria making you sick and the ones running your digestion, so they knock out both at once. You can protect your gut while you take the medicine and help it bounce back faster once you're done.
While you're taking itStart a
probiotic the same day you start your antibiotic. Look for Lactobacillus rhamnosus GG or Saccharomyces boulardii, both tied to fewer antibiotic-related stomach problems. Take it about two hours apart from your antibiotic dose, closer and the antibiotic can kill it off first.
The week or two afterKeep taking that probiotic for another one to two weeks after your last pill. This window matters most for rebuilding what got cleared out.
OngoingEat a wide range of plants, different vegetables, fruits, beans, whole grains, rather than the same three foods out of habit. Add a
fermented food daily, yogurt, kefir, sauerkraut, or kimchi. Go easy on alcohol and added sugar for a couple of weeks, since both tend to feed the less helpful bacteria that gained ground while the antibiotic was clearing everything else out.
How long recovery takes
Many people notice digestion settling down within four to eight weeks. Some bacterial species can take longer to fully return, so gradual improvement over that stretch is normal. Don't worry if week three still feels a little off. For a fuller week-by-week picture of what's normal along the way, use that timeline alongside this plan.
Call your doctor if, after two months:
You're still dealing with ongoing diarrhea, cramping that won't ease up, or bloating that keeps getting worse instead of better. Our guide to
recovering from a course of antibiotics covers what a longer recovery can look like.
What to do with this
The smallest move today: pick up a container of plain yogurt or kefir with your next grocery run. Everything else on this list can follow from there.
