Your gut problems might not be from what you’re eating — they could be from what you’re taking.
Some medications can quietly disrupt your gut microbiome — lowering good bacteria, encouraging overgrowth, and increasing inflammation.
Here are the ones I see most often in clinic:
💊 Antibiotics — Can reduce gut diversity for up to 16 months, sometimes wiping out species completely.
💊 PPIs (acid blockers) — Lower stomach acid, allowing overgrowth of unwanted bacteria, and reduce butyrate-producing microbes that protect your gut lining.
💊 NSAIDs (painkillers) — Increase harmful bacteria, reduce protective bugs like Lactobacillus and Bifidobacteria, and raise ulcer risk.
💊 Laxatives — Alter gut motility and microbiome balance, especially with overuse, leading to dependency and symptom cycles.
💊 Steroids — Suppress immune function in the gut, promote harmful bacteria, and slow microbiome recovery.
This isn’t about stopping your medication — it’s about understanding the side effects and supporting your gut while you’re on them.
