Why Antibiotics?
Whats a bacterial stomach infection?
When bacteria like nontyphoidal Salmonella, Shigella, certain E.coli strains, or Clostridioidesdifficile invade the gut, they can cause fever, cramps, and watery or bloody stools. Unlike a viral cold, these bugs thrive on nutrients that antibiotics can deny them.
Common bacterial culprits
- Salmonella often from undercooked eggs or poultry.
- Shigella spreads via contaminated water or close contact.
- Campylobacter found in raw or undercooked poultry.
- C.difficile can follow a course of broadspectrum antibiotics.
When do antibiotics actually help?
Guidelines from the and the World Health Organization recommend antibiotics only for confirmed bacterial gastroenteritis, severe cases with high fever, or when the child is at risk of dehydration. This careful approach protects your kids gut flora and slows the rise of antibiotic resistance.

Risks & Benefits
Common gastrointestinal upset
Its normal for a child on antibiotics to experience a bit of tummy turmoil. Research shows 13 out of 4 kids develop mild diarrhea or loose stools during treatment. Its usually shortlived, but keeping them hydrated is key.
Serious adverse events
Allergic reactions (hives, swelling, trouble breathing) are rare but require immediate medical care. In very rare cases, antibiotics can trigger a C.difficile infection, which presents as watery, foulsmelling diarrhea. If you notice blood, persistent fever, or severe pain, call your doctor right away.
Minimising guthealth impact
Probiotics are a friendly ally. Strains like Lactobacillus rhamnosus GG or Saccharomyces boulardii have evidence for reducing antibioticassociated diarrhea. Give them a few billion CFUs daily, preferably spaced a couple of hours from the antibiotic dose.
Sample probiotic dosing chart
| Age | Probiotic strain | Daily dose |
|---|---|---|
| 612mo | Lactobacillus rhamnosus GG | 5billion CFU |
| 13yr | Saccharomyces boulardii | 510billion CFU |
| 412yr | Lactobacillus rhamnosus GG | 10billion CFU |
How to Give
