Antibiotics, Anxiety and Your Gut
Tuesday, 17 February, 2026
Did you know a single course of antibiotics is linked to a 25% higher risk of anxiety and depression?Because antibiotics don’t just target the infection, the bad bacteria — they can disrupt the good gut bacteria that help regulate your brain.Educational content reviewed by licensed APRN medical staff. Not personal medical advice.In the video, Dr Vikki Petersen explains why there's an increased risk of anxiety and depression after taking antibiotics.Antibiotics kill both good and bad bacteria alike. Fewer beneficial bacteria means less control over inflammation.Inflammation can disrupt serotonin, dopamine, and the circuits that determine whether your brain feels calm or anxious.If you already deal with reflux, bloating, or constipation — common in hiatal hernia — the impact can be bigger and recovery slower.The increased risk shows up mainly in the months after treatment and can persist for up to about a year or longer. Many species rebound in weeks to a few months.Some do not fully return, especially after repeated exposure of antibiotics.Short chain fatty acids (SCFAs) are produced as a result of an abundance and variety of good bacteria. They strengthen the gut barrier - preventing leaky gut. With less leak, fewer inflammatory signals reach circulation resulting in less stimulation of brain immune cells.Too much activation of brain immune cells is associated with anxiety, depression, cognitive changes, and neurodegeneration.How does Hiatal Hernia fit in?Many people with hiatal hernia already have motility issues and microbial imbalance.That environment makes infections more likely.More infections often mean more antibiotics. And each round can deepen the imbalance.Hiatal hernia commonly overlaps with:impaired gastric emptyingaltered pressure gradientsreflux of stomach and small intestinal contentschanges in motilityfrequent acid suppression.All of those influence which organisms survive and where they grow.When movement and clearance are off, microbes accumulate in places they shouldn’t.TIPSFermented foods - think of them as reseeding the garden after the antibiotic has wiped out the pretty flowers, not just the bad weeds. Variety is key with fiber - gradual increase.Insoluble fiber - feeds the good bacteria and inc SCFA production. E.g. nuts, seeds, legumes, dark green leafies, psyllium, chia, flax, raspberries.Sleep - repair timeMovement - Regular moderate activity is linked with: greater diversity, better SCFA production, improved motility.Hydration supports stool transit, motility and mucosal healthStress regulation: A stressed brain sends stressed signals to the gut.Probiotics: They can help in certain situations, but they are not magic. After antibiotics, recovery isn’t about replacing one bug. It’s about rebuilding an environment where healthy microbes can grow againReferences:1. Lurie I, et al.
