🤢 Vet’s 2025 Guide to Vomiting vs. Regurgitation in Dogs and Cats: What Pet Parents Should Know 🐾
By Dr Duncan Houston, BVSc
Few things are as alarming—or messy—as when your pet suddenly brings something up. But not all “throwing up” is the same. Your vet will want to know whether your pet is vomiting or regurgitating. While they may look similar, they are very different medically. 🧠
This 2025 guide explains how to tell the difference between vomiting and regurgitation, what causes each, and when to call your veterinarian. 🐶🐱
🔍 Vomiting vs. Regurgitation: Key Differences
Vomiting is an active process. Your pet uses abdominal muscles to expel contents from the stomach or upper intestine. It’s often preceded by nausea and retching. 🤢
Regurgitation is passive. Food, liquid, or mucus is brought up from the esophagus without effort. It often happens quickly after eating. 😮💨
Here’s How to Tell the Difference:
| Feature | Vomiting | Regurgitation |
|---|---|---|
| Effort | Active—heaving and retching | Passive—no effort or heaving |
| Timing | Varies—before or after eating | Usually soon after eating or drinking |
| Appearance | Partially digested food, bile, foam | Undigested food, mucus—often tubular |
| pH | Acidic | Usually neutral unless stomach contents present |
| Bile present? | Often | Rarely |
🎥 What It Looks Like
Vomiting: Pets often drool, look nauseated, and show abdominal contractions. Watch for signs like lip-smacking or swallowing excessively. 🌀
Regurgitation: Sudden, quiet. Food may spill from the mouth without warning. It may appear like a gentle “burp” with a surprise. 🫢
💡 Why Does the Difference Matter?
Each process has different underlying causes—and different diagnostic paths. 🩺
Common Vomiting Causes:
- 🦴 Dietary indiscretion (“garbage gut”)
- 💊 Medication reactions
- 🧫 Infections (parvo, pancreatitis, parasites)
- 🧠 Motion sickness or toxins
- 🦠 Organ disease (kidney, liver)
Common Regurgitation Causes:
- 🧬 Congenital issues (megaesophagus)
- 🎯 Obstructions or esophageal strictures
- 🧠 Nerve damage
- 🦠 Muscle disease or myasthenia gravis
🧪 What to Tell Your Vet
Your observations can help your vet diagnose correctly. Try to note:
- 🕒 Time since eating
- 🔄 Frequency and duration of episodes
- 🎨 Appearance of the expelled material (bile, blood, shape)
- 📽️ A video (if possible) of the event
🩺 What Tests May Be Needed?
For Vomiting:
- 🧪 Bloodwork (CBC, chemistry panel)
- 📸 Abdominal X-rays or ultrasound
- 🔬 Stool test for parasites
For Regurgitation:
- 📸 Chest X-rays (for megaesophagus)
- 🧫 Esophageal endoscopy
- 🧬 Nerve/muscle function tests
📛 When to Be Concerned
Call your vet if you notice:
- 🚨 Blood in vomit or regurgitated material
- ⏱️ Vomiting or regurgitation that lasts more than 24 hours
- ⚖️ Weight loss or poor appetite
