#40 The Hidden Gut Effects of Omeprazole: What It’s Really Doing to Your Pet’s Microbiome

Omeprazole is one of the most commonly prescribed medications in veterinary medicine, and it often is for good intent. It can be helpful in the right situations. But what happens when it’s used long-term or without a clear reason?

In this episode, I break down what omeprazole is actually doing inside your pet’s body beyond just “reducing stomach acid.” We talk about how it shifts the gut environment, alters the microbiome, and why that matters for overall health.

I also dive into one of the lesser-known downstream effects: how acid suppression can reduce beneficial bacteria like Peptoclostridium hiranonis, which plays a key role in bile acid conversion and gut protection. When that balance is disrupted, it can open the door to dysbiosis and opportunistic overgrowth.

This is not about fear, it’s about awareness. Because when we understand the full picture, we can make more intentional, informed decisions for our pets.

If your pet has ever been on omeprazole (or is currently on it), this is an episode you don’t want to miss.

What You’ll Learn:
• What omeprazole is 
• Why stomach acid is essential for digestion and protection

• How reduced bile acid conversion can contribute to dysbiosis
• The potential long-term ripple effects on gut health and immunity
• Why omeprazole is often overused in pets
• How to start thinking more intentionally about gut health and medications
