Bloating is one of the most common digestive complaints I see — and it’s also one of the most misunderstood.

For some people, it’s a mild “puffy” feeling after meals. For others, it’s visible distension, pressure under the ribs, painful gas, reflux, constipation, or a belly that gets bigger as the day goes on. The key naturopathic perspective is this:

Bloating is rarely random.
It’s usually a sign that digestion, motility, microbes, hormones, or the nervous system need support — often in combination.

Below are 10 evidence-informed, naturopathic root causes of bloating, written in a way you can use for your JIVANA Journal blog (and for client education).

---

First: What is bloating?

“Bloating” can refer to:

• Gas production (fermentation)
• Fluid shifts in the bowel (osmotic effects)
• Slowed motility (gas + stool not moving)
• Visceral hypersensitivity (you feel normal gas more strongly)
• Inflammation and gut barrier disruption

Often, several are happening at once.

---

1) Low Digestive Enzymes (Poor Breakdown → Fermentation)

If digestive enzymes are low, food isn’t broken down efficiently — particularly proteins and fats. Undigested food becomes fuel for fermentation further down the tract, increasing gas and distension.

This can be seen with:

• chronic stress (digestive secretions reduce)
• gut inflammation
• pancreatic insufficiency (less common, but important to rule out if there’s oily stools or weight loss)

Clinical clue: heaviness after protein-rich meals, feeling “full” quickly, lots of post-meal gas.

---

2) “Too Much” Acid / Hyperacidity (Irritation + Reactive Bloating)

While low stomach acid is common, some people experience excessive acidity or mucosal irritation that can feel like bloating, burning, reflux, nausea, or upper abdominal pressure.

Gastric physiology is complex, and acid balance matters for both digestion and microbial control. PubMed

Clinical clue: burning, reflux, upper stomach discomfort (often worse with coffee, alcohol, spicy food, or stress).

---

3) Low Stomach Acid (Hypochlorhydria) — a Big One

Adequate stomach acid helps:

• begin protein digestion
• activate enzymes (like pepsin)
• act as a first line of defence against microbes entering from food PubMed

Research links low-acid environments with changes in upper-GI microbes and dysbiosis risk. PubMed

Clinical clue: reflux that doesn’t always improve long-term, bloating after meals, feeling heavy after meat, frequent burping, and sometimes nutrient issues (iron/B12).

---

4) Dysbiosis, SIBO (Small Intestinal Bacterial Overgrowth) & “IMO/LIBO”

When bacteria (or methanogens) are living where they shouldn’t — especially the small intestine — fermentation happens quickly and intensely.

SIBO is known for symptoms like bloating, distension, gas, abdominal discomfort, diarrhoea or constipation. PubMed+1

Clinical clue: bloating within 20–60 minutes of eating, and worse with carbs, fibre, or “healthy foods” like legumes.

---

5) Impaired Bile Flow (Liver/Gallbladder Support) — Fat Digestion Matters

Bile isn’t just for cholesterol — it’s critical for:

• emulsifying fats
• supporting motility
• shaping microbial balance

When bile flow is sluggish, fats can sit longer in the gut and contribute to fullness, nausea, and bloating after rich meals. Bile-acid related disorders can also present with abdominal symptoms and excessive gas/flatulence. PMC+1

Clinical clue: bloating after fatty meals, nausea, pale stools, or a “heavy” upper-right abdomen sensation.

---

6) Constipation + Slow Transit (Gas Gets Trapped)

If stool transit slows, gas builds up behind it — and the abdomen distends. Slow-transit constipation is a recognised functional disorder, and constipation itself commonly creates bloating and pressure. PubMed

Clinical clue: bloating that worsens through the day, relief after bowel motions, incomplete evacuation, or going less than daily.

---

7) Gut Barrier Disruption + Low-Grade Inflammation

A sensitive, inflamed gut can feel bloated even when gas volume isn’t dramatically higher — because the gut becomes more reactive.

Increased intestinal permeability has been described across a range of gastrointestinal disorders, and the “gut barrier” is tightly linked to immune activation and inflammation. PubMed+1

Clinical clue: bloating plus food sensitivity patterns, IBS-like symptoms, or flares after alcohol, NSAIDs, stress, or processed foods.

---

8) Nervous System Dysregulation (The Brain–Gut Axis & Vagus Nerve)

Digestion is a parasympathetic process. If your body is living in “fight-or-flight,” your gut may downshift:

• enzyme secretion
• stomach acid output
• motility
• vagal tone

Low vagal tone is observed in functional digestive disorders, and the vagus nerve plays a major role in motility, sensitivity, and inflammation regulation. PubMed+1

Clinical clue: bloating that tracks with stress, deadlines, conflict, poor sleep, or burnout — even with “perfect” food.

---

9) FODMAP / Food Chemical Sensitivities (Osmosis + Fermentation)

Certain fermentable carbohydrates (FODMAPs) increase bloating via:

• pulling water into the bowel
• fermenting rapidly and producing gas

Controlled trials and reviews show low-FODMAP approaches can significantly improve IBS symptoms, especially bloating and pain. PubMed+2PubMed+2

Clinical clue: bloating after onions/garlic, wheat, apples, stone fruit, legumes, some dairy, or sugar alcohols.

---

10) Hormones (Cycle, Perimenopause, Pregnancy) Affect Motility + Fluid Balance

Hormones shift gut transit and sensitivity. Classic research demonstrates that GI transit time can be prolonged in the luteal phase when progesterone is higher. PubMed

Progesterone has been reviewed for its inhibitory effects on GI motility mechanisms. PubMed

Clinical clue: bloating peaks premenstrually, around ovulation, during pregnancy, or during perimenopause (often alongside constipation).

Where JIVANA Teas Fit In (Supportive Ritual + Botanical Calm)

Bloating is best addressed by finding your root cause — but gentle herbal support can be a beautiful part of the plan, especially when symptoms involve irritation, spasm, reflux, stress, or sluggish bowels.

JIVANA Digest-Ease Tea (soothing + antispasmodic support)

Your Digest-Ease Tea is formulated to support the irritated digestive tract and help calm digestive spasm (often felt as “tight,” “stuck,” or “burning” digestion). The ingredients include traditional soothing and carminative herbs like marshmallow, chamomile, fennel and licorice (plus your other clinically chosen botanicals). Jivana
There’s also human clinical evidence for fennel essential oil improving IBS symptom scores (including symptom domains like bloating/pain). PubMed
Licorice extract has also shown benefit in functional dyspepsia symptoms in a randomized placebo-controlled study. PubMed

JIVANA Cleanse Tea (short-term bowel support + post-indulgence reset)

Your Cleanse Tea is designed for short-term support when bloating is driven by sluggish elimination or “heavy food weekends,” using ingredients like senna, plus carminatives such as fennel/aniseed and warming spices. Jivana
Senna has evidence for improving bowel movement frequency and constipation outcomes in randomized trials. PubMed

Important note (aligned with your product guidance): senna should be used short-term and is not appropriate in pregnancy.

When bloating should be investigated (red flags)

If any of these are present, refer for medical evaluation:

• unexplained weight loss
• persistent vomiting
• blood in stool / black stools
• anaemia, persistent fever
• severe pain that’s new or worsening
• new bowel habit change lasting >4–6 weeks
