Leaky Gut vs. IBS vs. SIBO: What’s the Difference?
Introduction: Understanding Your Gut Issues
Do you constantly deal with bloating, digestive discomfort, food intolerances, or fatigue—but no doctor seems to give you a clear answer?
Many people are misdiagnosed with Irritable Bowel Syndrome (IBS) when they actually have Leaky Gut or SIBO (Small Intestinal Bacterial Overgrowth).
📌 Why does this matter?
✔ Leaky Gut, IBS, and SIBO all have similar symptoms (bloating, gas, diarrhea, constipation).
✔ But they have different root causes & need different treatments.
✔ Misdiagnosis leads to the wrong treatment, making symptoms worse.
💡 This guide will help you understand the key differences and how to heal naturally.
1️⃣ What is Leaky Gut?
Leaky gut (intestinal permeability) occurs when the lining of your intestines becomes damaged, allowing toxins, bacteria, and undigested food particles to leak into your bloodstream.
Symptoms of Leaky Gut:
✔ Chronic bloating & gas
✔ Food sensitivities (gluten, dairy, nuts)
✔ Brain fog & fatigue
✔ Skin conditions (eczema, acne, rashes)
✔ Joint pain & inflammation
✔ Autoimmune diseases (thyroid, rheumatoid arthritis)
What Causes Leaky Gut?
🔹 Chronic inflammation (processed foods, sugar, alcohol)
🔹 Gut infections (candida, parasites, H. pylori)
🔹 Excess antibiotics & NSAIDs (damaging gut lining)
🔹 Dysbiosis (gut bacteria imbalance)
💡 Leaky gut is a root cause of autoimmune diseases, food intolerances, and chronic inflammation.
2️⃣ What is IBS (Irritable Bowel Syndrome)?
IBS is a functional gut disorder that causes abnormal bowel movements, bloating, and digestive distress without any visible disease.
Symptoms of IBS:
✔ Alternating diarrhea & constipation
✔ Abdominal pain & cramping
✔ Excess gas & bloating
✔ Urgency to use the bathroom after eating
✔ Mucus in stool
What Causes IBS?
🔹 Dysregulated gut-brain axis (stress, anxiety)
🔹 Food intolerances (gluten, dairy, high-FODMAP foods)
🔹 Gut infections (H. pylori, Candida, post-infectious IBS)
🔹 Slow digestion & bile dysfunction
📌 IBS is often diagnosed when doctors can’t find another cause for symptoms—but IBS is a symptom, NOT a root cause!
3️⃣ What is SIBO (Small Intestinal Bacterial Overgrowth)?
SIBO occurs when bacteria that should be in the large intestine overgrow in the small intestine, causing excessive fermentation and gas production.
Symptoms of SIBO:
✔ Severe bloating after eating
✔ Chronic diarrhea or constipation
✔ Belching, acid reflux, heartburn
✔ Nutrient deficiencies (B12, iron)
✔ Unexplained weight loss or weight gain
✔ Chronic fatigue
What Causes SIBO?
🔹 Slow gut motility (hypothyroidism, stress, fasting too long)
🔹 Low stomach acid (H. pylori, PPI medications, aging)
🔹 Chronic constipation (traps bacteria in the small intestine)
🔹 Poor bile flow (gallbladder issues, liver congestion)
📌 SIBO is often misdiagnosed as IBS—but IBS treatments won’t fix SIBO!
4️⃣ Key Differences Between Leaky Gut, IBS, and SIBO

💡 If you have bloating after meals, IBS-like symptoms, and worsening food sensitivities, you might have more than just IBS!
5️⃣ Natural Healing Approach for Each Condition
How to Heal Leaky Gut Naturally
✔ Remove inflammatory foods (gluten, dairy, sugar, alcohol)
✔ Repair the gut lining (bone broth, L-glutamine, aloe vera, licorice root)
✔ Support digestion (ginger, digestive bitters, apple cider vinegar)
How to Heal IBS Naturally
✔ Manage stress & gut-brain connection (meditation, yoga, vagus nerve exercises)
✔ Identify trigger foods (keep a food journal, test for intolerances)
✔ Optimize digestion (bitter foods, digestive enzymes, fermented foods)
How to Heal SIBO Naturally
✔ Follow a low-FODMAP diet temporarily
✔ Use natural antimicrobials (oregano oil, neem, berberine)
✔ Improve motility with prokinetics (ginger, Triphala, magnesium citrate)
📌 Each condition requires a different healing protocol—so proper diagnosis is key!
6️⃣ Final Thoughts: Which One Do You Have?
If you’ve been struggling with gut issues for years and standard IBS treatments haven’t worked, it’s time to go deeper.
💡 The right diagnosis = the right treatment = real healing.
