Heidelberg pH capsule test for stomach acid and gastric function in Los Angeles

Heidelberg pH Testing for Gastric Function Assessment

The Heidelberg test measures your stomach acid production non-invasively. Using a tiny wireless pH capsule, we assess whether you produce adequate acid for digestion, identify acid reflux patterns, and evaluate gastric healing.

This test provides crucial information guiding personalized treatment of reflux, ulcers, and digestive dysfunction.

Why Stomach Acid Matters

Adequate stomach acid is essential for:
– Protein digestion
– Mineral absorption
– Pathogen elimination
– Nutrient bioavailability
– Digestive signaling

Many people have insufficient acid production (hypochlorhydria), causing malabsorption and digestive dysfunction. Conversely, others have excessive acid causing reflux and ulcers.

How the Heidelberg Test Works

  • Swallow wireless pH capsule with bicarbonate tablet
  • Capsule measures stomach pH continuously for 24 hours
  • Data transmitted wirelessly to recording device
  • Capsule dissolves and passes naturally
  • Data analyzed for acid production patterns and reflux timing

What the Test Reveals

  • Stomach acid production level
  • Acid recovery time after buffer
  • Reflux episodes and timing
  • Acid suppression medication effectiveness
  • Gastric emptying patterns
  • Whether acid suppression therapy is needed or excessive

Conditions Evaluated

  • GERD and chronic reflux
  • Hypochlorhydria (low acid)
  • Ulcers and gastritis
  • Malabsorption patterns
  • Medication effectiveness monitoring

Preparation

  • Stop acid-suppressing medications 3-5 days before (discuss timing with our office)
  • Fast 12 hours before test
  • Avoid certain medications (discuss with physician)
  • Continue other medications as normal

Treatment Based on Results

If acid is insufficient, we implement:
– Bitters and digestive support
– Betaine HCl supplementation
– Dietary modifications supporting digestion
– Healing protocols

If acid is excessive, we implement:
– Dietary modifications
– Natural acid reducers
– Stress management
– Healing protocols

Frequently Asked Questions

Is it safe to stop acid-suppressing medications before the test?

For the 3-5 days before testing, yes, stopping is safe for most people. We’ll provide specific guidance based on your situation. If you have severe reflux, we may use alternative protocols to minimize symptoms during this period.

What if I have low stomach acid?

Low acid can be treated through supplementation (betaine HCl), bitters to stimulate acid production, dietary modifications, and treating underlying causes. Many people improve significantly with targeted interventions.

What if I have high stomach acid?

High acid requires identifying the root cause—often stress, dysbiosis, or food sensitivities. We address root causes rather than just suppressing acid long-term, which can cause nutritional deficiencies.

How long do I wear the capsule?

The wireless capsule records for 24 hours. You wear the recording device (about the size of a pager) clipped to your belt or carried in your pocket. After 24 hours, the capsule dissolves naturally.

When will I get results?

Data is analyzed and reviewed by your physician within 3-5 business days. We schedule a follow-up appointment to discuss findings and treatment recommendations.

Can I eat during the test?

Yes. The test is designed to measure your stomach’s response to normal eating. You’ll eat and drink normally during the 24-hour recording period. This provides valuable real-world pH data.
