Why do I have heartburn every day despite medication?
Daily heartburn despite medication most often happens because the medicine is taken at the wrong time or inconsistently, the dose is too low, reflux triggers continue, or the symptoms are not caused by acid at all. Other common reasons include a hiatal hernia, non-acid or bile reflux, reflux hypersensitivity or functional heartburn, eosinophilic esophagitis, slow stomach emptying, and esophageal muscle disorders. Testing sorts out which applies.
Three broad reasons heartburn persists
- Medicine issuesWrong timing, missed doses or a dose that is too low for your reflux.
- Ongoing refluxHiatal hernia, late meals, weight or non-acid reflux that medicine cannot fully stop.
- Different causeHypersensitivity, eosinophilic esophagitis, motility problems or slow stomach emptying.
Am I taking my reflux medicine correctly?
Most proton pump inhibitors work best when taken 30 to 60 minutes before breakfast every day, followed by a meal, because they block acid pumps that switch on with food. Taking them at bedtime, after eating, or only when symptoms flare makes them much less effective. If night-time heartburn continues, your doctor may adjust the dose or timing or add a bedtime medicine.
Tip: Check timing before changing medicine
Before assuming a medicine has failed, take it every day for two weeks, 30 to 60 minutes before breakfast, and keep a heartburn log. Many people improve with timing alone.

What else can cause heartburn that medicine does not fix?
Heartburn that does not respond to acid-reducing medicine can come from non-acid or weakly acidic reflux, bile reflux, a large hiatal hernia, reflux hypersensitivity or functional heartburn, eosinophilic esophagitis (an allergic inflammation of the esophagus), esophageal spasm or achalasia, gastroparesis, and pill irritation of the esophagus. Some of these need entirely different treatment.
| Possible cause | Typical clues | How it is found |
|---|---|---|
| Ongoing acid reflux | Classic heartburn, worse at night | pH-impedance testing |
| Hiatal hernia | Regurgitation, worse lying down | Upper endoscopy or barium study |
| Reflux hypersensitivity | Heartburn with normal acid levels | pH-impedance with symptom matching |
| Eosinophilic esophagitis | Food sticking, allergies | Endoscopy with biopsies |
| Motility disorder | Trouble swallowing, chest pressure | Esophageal manometry |
| Gastroparesis | Early fullness, nausea, vomiting | Gastric emptying study |
What tests find the cause of persistent heartburn?
The main tests for persistent heartburn are an upper endoscopy (EGD) with biopsies to look for esophagitis, a hiatal hernia, Barrett’s esophagus or eosinophilic esophagitis; esophageal pH or pH-impedance monitoring to measure acid and non-acid reflux and match it to symptoms; and esophageal manometry to check how the esophageal muscle works. A gastric emptying study may be added for nausea or early fullness.
Your evaluation, step by step
- Review medicinesDr. Khan checks timing, dose and other medicines that irritate the esophagus.
- EndoscopyLooks at the esophagus and stomach and takes biopsies.
- Reflux testingpH or pH-impedance monitoring, and manometry when needed.
- Targeted planTreatment matched to the confirmed cause.
What treatments help when reflux medicine is not enough?
When standard reflux medicine is not enough, options include adjusting the timing or dose of a proton pump inhibitor, adding an alginate or a bedtime acid reducer, strengthening lifestyle measures such as weight loss and head-of-bed elevation, and treating any other cause found on testing. People with confirmed ongoing reflux, especially with a hiatal hernia, may be candidates for anti-reflux surgery or an endoscopic procedure. Hypersensitivity is often treated with medicines that calm esophageal nerves.

Key takeaways
- Heartburn every day despite medication often comes from medicine timing, dose or ongoing triggers.
- Proton pump inhibitors work best 30 to 60 minutes before breakfast, taken daily.
- Non-acid reflux, hiatal hernia, hypersensitivity and eosinophilic esophagitis are common hidden causes.
- Endoscopy, pH-impedance testing and manometry identify the cause.
- Treatment options include medicine changes, procedures or surgery, depending on the results.
Frequently asked questions
What if omeprazole is not working?
Check that you take it daily, 30 to 60 minutes before breakfast. If symptoms persist after several weeks, see a gastroenterologist for testing rather than simply adding more over-the-counter medicine.
Can you have heartburn without acid?
Yes. Non-acid reflux, bile reflux and hypersensitive esophageal nerves can all cause heartburn-like burning.
Should I switch to a different reflux medicine?
Sometimes a different medicine or dose helps, but it is best to find the cause first. Your doctor can guide any change.
When is surgery considered for GERD?
Surgery or an endoscopic procedure may be considered when testing confirms ongoing reflux that medicine does not control, especially with a hiatal hernia.
Do I need a referral to see a gastroenterologist in Katy or Cypress?
It depends on your insurance plan. Many PPO plans let you book a specialist directly, while some HMO plans require a referral from your primary care doctor. Call (346) 340-4414 and the team can help you check.
