Introduction: Heartburn Is More Than Just a Nuisance

You’ve likely felt it—a burning sensation in your chest, a bitter taste in your throat, maybe even a chronic cough or hoarseness. These are classic symptoms of heartburn, also known as acid reflux or GERD (gastroesophageal reflux disease).

Most people treat it with antacids or proton pump inhibitors (PPIs), but here’s the truth: heartburn is a symptom, not the root problem.

In functional medicine, we view heartburn as a signal that something deeper is going wrong in your digestive system. In this article, we’ll explore what heartburn symptoms really mean, the most common root causes, and how to fix it naturally and sustainably.

What Exactly Is Heartburn?

Heartburn occurs when stomach acid flows backward into the esophagus. The esophagus isn’t equipped to handle this acid, which causes a burning or painful sensation.

Common heartburn symptoms:

• Burning in the chest (especially after meals or lying down)
• Regurgitation or sour taste in the mouth
• Chronic cough or throat clearing
• Hoarseness or sore throat
• Bloating or belching
• Feeling like food is “stuck” after swallowing

Occasional heartburn is common, but frequent symptoms may signal a deeper dysfunction.

What Heartburn Symptoms Might Really Mean

Let’s explore what your heartburn might be telling you—beyond just “too much acid.”

1. Low Stomach Acid (Hypochlorhydria)

One of the biggest misconceptions is that heartburn is caused by too much stomach acid. In reality, many people have too little.

Stomach acid plays an essential role in:

• Breaking down protein
• Absorbing nutrients (B12, calcium, iron, zinc)
• Killing pathogens and bacteria
• Triggering the closure of the lower esophageal sphincter (LES)

When stomach acid is too low, food sits in the stomach too long and ferments, creating gas and pressure that forces acid up into the esophagus.

Signs of low stomach acid:

• Bloating or fullness after small meals
• Belching or gas
• Poor digestion of protein (meat feels heavy)
• Nutrient deficiencies
• Reflux symptoms that worsen after taking antacids

✅ Functional tip: Try the betaine HCl test with professional guidance to assess low acid levels.

2. Impaired Function of the Lower Esophageal Sphincter (LES)

The LES is a muscular ring that opens to let food into the stomach and closes to prevent acid from flowing back up. If it becomes weak or too relaxed, acid reflux occurs.

What can weaken the LES:

• Obesity or excess abdominal pressure
• Hiatal hernia
• Smoking
• Caffeine or alcohol
• Certain medications (e.g., NSAIDs, muscle relaxants)
• Chronic inflammation from poor diet

When the LES malfunctions, even normal levels of acid can cause reflux.

✅ Functional tip: Losing abdominal weight, avoiding trigger foods, and eating smaller meals can help reduce LES dysfunction.

3. H. pylori Infection

Helicobacter pylori is a common bacterial infection that affects the stomach lining and is linked to ulcers, gastritis, and chronic reflux.

H. pylori disrupts acid production and leads to:

• Inflammation of the stomach lining
• Decreased digestive enzyme output
• Increased risk of gastritis and ulcers
• Acid imbalance and reflux symptoms

Up to 50% of the global population is estimated to carry H. pylori, often unknowingly.

✅ Functional tip: Get tested for H. pylori via stool antigen, breath test, or biopsy. Natural eradication options include mastic gum, DGL, berberine, and zinc carnosine.

4. Food Sensitivities and Gut Dysbiosis

Food sensitivities (not allergies) can contribute to gut inflammation, bloating, and reflux.

Common food triggers:

• Gluten
• Dairy
• Spicy foods
• Citrus
• Nightshades (tomatoes, peppers)
• Processed foods and preservatives

Dysbiosis (imbalanced gut bacteria) can also contribute to gas production and LES pressure.

✅ Functional tip: Try an elimination diet for 3–4 weeks to uncover potential food triggers and calm gut inflammation.

5. Stress and the Gut-Brain Axis

Chronic stress impacts digestion dramatically by:

• Suppressing stomach acid production
• Slowing motility (leading to delayed emptying)
• Increasing inflammation and gut permeability
• Disrupting the vagus nerve-gut connection

Stress-induced heartburn is very common, especially in high-pressure lifestyles.

✅ Functional tip: Incorporate stress-reducing practices like deep breathing, vagus nerve stimulation, yoga, or mindful eating (chewing thoroughly, eating slowly without screens).

Why Antacids and PPIs May Make Things Worse

While antacids and PPIs (like omeprazole) offer short-term relief, they don’t address the root cause—and long-term use comes with significant risks.

Side effects of long-term acid suppression:

• B12, magnesium, calcium, and iron deficiencies
• Increased risk of osteoporosis
• Greater susceptibility to infections like C. difficile and SIBO
• Rebound acid hypersecretion when stopping PPIs
• Poor protein digestion

Instead of suppressing symptoms, functional medicine aims to correct the underlying imbalance.

Natural Solutions for Heartburn Relief

Here’s how we help patients in our practice eliminate reflux symptoms and rebuild digestive health:

1. Test, Don’t Guess

• Stool test (GI-MAP or similar) to look for H. pylori, dysbiosis, and inflammation
• Food sensitivity testing (or guided elimination diet)
• SIBO breath testing
• Betaine HCl trial (under supervision)

2. Repair and Rebalance the Gut

• L-glutamine, zinc carnosine, and DGL for healing the gut lining
• Digestive bitters or HCl for low acid
• High-quality probiotics to restore microbial balance

3. Optimize Eating Habits

• Eat slowly, chew thoroughly, and avoid overeating
• Sit upright after meals
• Avoid eating late at night
• Drink most fluids away from meals

4. Manage Stress and the Nervous System

• Meditation, breathwork, grounding
• Support the vagus nerve with cold exposure, gargling, or humming
• Sleep hygiene to support digestion and healing

Final Thoughts: Listen to What Your Heartburn Is Saying

Heartburn is not just an annoyance—it’s a message from your body. Rather than suppressing the symptoms, ask why they’re happening.

By uncovering and addressing the root causes—like low stomach acid, gut infections, food sensitivities, and stress—you can heal your digestion, eliminate reflux, and feel better long term.
