Heartburn and Acid Reflux

What is Heartburn and Acid Reflux?

Heartburn is a burning feeling behind the breastbone, and acid reflux is the backward flow of stomach contents into the esophagus that most often causes it. Heartburn and regurgitation are the typical symptoms of gastroesophageal reflux disease (GERD), the chronic form of reflux.^{[1, 2]} Occasional heartburn is common, and the research on complementary care is mostly done in people with GERD.

Common symptoms

Heartburn, regurgitation and chest pain that does not come from the heart are the most common symptoms.^[1] Some people notice a sour or bitter taste, a sore throat, hoarseness or a cough that is worse at night. Because chest pain can come from the heart, any new or unexplained chest pain needs a physician's assessment first.

Causes and risk factors

Reflux happens when the valve at the bottom of the esophagus lets stomach contents through. In a meta-analysis of population studies, reflux symptoms were more common with age 50 or older, smoking, NSAID or aspirin use and obesity, although the associations were modest.^[3]

Many people report that large meals, fatty or spicy foods, chocolate, coffee or alcohol bring on symptoms. Late evening meals increase time with acid in the esophagus when lying down, and weight loss and quitting smoking are advised when they apply.^[4] Triggers differ from person to person.

How it is diagnosed and treated conventionally

Heartburn that happens often is usually diagnosed from the symptoms, and a physician may suggest a short trial of a proton pump inhibitor (PPI). Testing such as endoscopy and pH monitoring is used when symptoms do not respond or when warning signs are present.^{[1, 5]}

Treatment starts with meal and lifestyle changes, including avoiding late meals and raising the head of the bed.^[4] Antacids give short relief, alginates (which work by displacing the pocket of acid that collects after meals) relieved reflux symptoms more than placebo or antacids in a meta-analysis, and acid-reducing medicines are used when symptoms are frequent.^{[2, 6]} Up to half of people with suspected GERD do not benefit from acid suppression, which is one reason a physician may look for other explanations.^[5]

Why Heartburn and Acid Reflux calls for a whole-person approach

Heartburn does not depend on acid alone. Meal timing, body weight, stress, and how the esophagus and stomach move can all affect it, and some people keep having symptoms despite acid-reducing medicine.^{[5, 7]}

Complementary care is aimed at some of these other factors and is used together with medical advice and acid-reducing treatment.

Meals, weight and daily habits

Lifestyle changes have the best support among self-care steps. Weight loss in people who are overweight, stopping smoking, avoiding late meals and raising the head of the bed each have evidence in reviews of trials and cohort studies.^[4]

Stress, mood and the brain-gut link

A meta-analysis of 36 studies found anxiety and depressive symptoms were more common in people with GERD than in healthy controls, and the link appeared to go both ways.^[8] An expert review from the American Gastroenterological Association advises relaxation strategies and awareness of the brain-gut relationship for people with reflux symptoms.^[5]

How the esophagus and stomach move

Weak esophageal contractions and slow stomach relaxation after eating can contribute to reflux. In a 30-patient sham-controlled trial, 4 weeks of acupoint electrical stimulation through the skin improved these functions and reflux symptom scores.^[9]

Acupuncture for Heartburn and Acid Reflux

What the research shows

Acupuncture may help reflux symptoms, but the evidence is limited. A meta-analysis of 12 trials with 1,235 patients found better overall symptom improvement when acupuncture was added to Western medicine than with Western medicine alone, and less recurrence with acupuncture alone than with medication, while global symptom improvement with acupuncture alone was similar to medication. Its authors noted small samples and poor methods.^[10] A 2025 meta-analysis rated the certainty of its findings very low to low, found global symptom improvement was lower with acupuncture than with PPIs, and did not recommend manual acupuncture alone as the main treatment.^[11] A network meta-analysis found acupoint stimulation with Chinese medicine improved lower esophageal sphincter pressure and acid exposure, but not quality-of-life scores.^[12]

In one trial of 72 adults whose symptoms persisted on a daily PPI, acupuncture plus the standard dose gave a greater reduction in heartburn than a doubled PPI dose, while the doubled dose worked better for regurgitation and sleep disturbance. Total reflux scores did not differ between groups. The trial had no sham group.^[7]

How acupuncture may work

Researchers propose that acupoint stimulation may act through the vagus nerve to improve how the esophagus and stomach move. In a small sham-controlled trial, vagal activity increased with stimulation and was correlated with sphincter pressure and esophageal contractions.^[9] These are proposed mechanisms from small studies, not settled facts.

What treatment involves

Treatment uses fine, sterile, single-use needles at points on the abdomen, wrist and lower leg, usually left in place for about 20 to 40 minutes. The trials above lasted about four weeks or longer, and we reassess after a short course of visits.^[7]

Serious problems are rare. In prospective studies, about 9 in 100 patients had a minor reaction such as soreness, bleeding or redness at a needle site, and serious events occurred in about 1 in 10,000 patients.^[13] Tell the practitioner first if you have a bleeding disorder, take blood thinners, are pregnant, or have a pacemaker (relevant to electroacupuncture).

Ayurvedic medicine for Heartburn and Acid Reflux

The Ayurvedic view

In Ayurveda, heartburn with sour belching is described as Amlapitta, and the upward form as Urdhwaga Amlapitta. It is traditionally seen as an aggravation of Pitta, the principle linked to heat and digestion, tied to diet and lifestyle.^[14] These are traditional categories, not biomedical diagnoses.

Therapies that may be used

Care is chosen for the individual and traditionally combines:

• Regular, moderate meals with cooling, bland foods, and less very spicy, sour, fried or late-evening food, which matches the medical advice above^[4]
• Daily routine and relaxation practices such as slow breathing
• Herbs such as licorice root (Yashtimadhu), used traditionally for Amlapitta^[15]
• Individually prescribed formulas from tested sources, since some Ayurvedic products contain heavy metals^[16]

Panchakarma procedures, especially vomiting or purgation therapies, are not routinely suited to reflux. They are not appropriate in pregnancy, acute illness, frailty, or before warning symptoms have been medically assessed.

What the research shows

The research on Ayurveda for heartburn is very limited. Studies mostly concern Amlapitta or non-ulcer dyspepsia, not reflux confirmed by testing. A single-arm study of 30 patients given individualized herbo-mineral treatment for 28 days reported symptom relief, but had no control group.^[14] A 40-patient study of two licorice-type roots reported that burning in the chest and throat eased in both groups, without a placebo arm.^[15] Evidence for heartburn itself is uncertain.

Herbal medicine for Heartburn and Acid Reflux

Herbs and formulas that have been studied

Most research is on Chinese herbal formulas for GERD, including Jianpi (spleen-strengthening) and Ligan Hewei (liver-soothing, stomach-harmonizing) approaches and the formula Wu Zhu Yu Tang.^{[17, 18]}

What the research shows

The evidence is limited. A network meta-analysis of 17 trials with 1,441 participants suggested Jianpi and Ligan Hewei approaches, alone or with PPIs, may be useful complementary options, and called for better-designed trials.^[17] In a double-blind trial of 204 people with nonerosive reflux, a Jianpi Qinghua granule plus half-dose PPI gave more complete symptom resolution at 4 weeks than a standard-dose PPI, though sufficient relief did not differ.^[19] In a 90-patient double-blind trial (77 completed), Wu Zhu Yu Tang gave symptom scores similar to omeprazole, and the authors asked for larger studies.^[18] Nearly all of this work is from East Asia.

Safety and herb-drug interactions

Herbs can cause side effects. In the Jianpi Qinghua trial, three people in the herb-plus-PPI group developed liver dysfunction, two of them moderate to severe.^[19] Tell us if you have liver or kidney disease, are pregnant or breastfeeding, take blood thinners, or have surgery planned. Herbs should be checked against all your medicines.

Licorice, which is used traditionally for reflux, can raise blood pressure and lower potassium and needs caution in pregnancy.^[20] About one fifth of Ayurvedic products bought online contained detectable lead, mercury or arsenic.^[16] Herbs should come from tested sources and be prescribed individually.

Translating traditional medicine into modern biological language

This is interpretation, not equivalence. Chinese medicine often describes reflux as stomach qi rising when it should descend, sometimes with liver qi stagnation or spleen weakness. Researchers studying acupuncture measure things that loosely parallel this: vagal nerve activity, lower esophageal sphincter pressure and esophageal and stomach movement.^{[9, 12]}

Ayurveda's aggravated Pitta describes heat and burning in the upper digestive tract, linked to diet and lifestyle.^[14] No study has shown that a dosha corresponds to a specific biological process.

How this care fits with your medical care

Integrative care for heartburn is complementary. Do not stop, reduce or change a PPI, antacid or any prescribed medicine without your prescriber. Heartburn that is frequent, has lasted weeks, or is not controlled by medicine should be evaluated by a physician, because we do not diagnose the cause of reflux.

Please bring your diagnosis, any endoscopy or pH results, and a full list of medicines and supplements, including over-the-counter antacids.

When to seek urgent medical care

Some symptoms point to a complication or to a different, more serious problem such as a heart condition.^[1]

• Chest pain or pressure, especially with shortness of breath, sweating, or pain spreading to the arm or jaw
• Trouble or pain with swallowing, or food that feels stuck
• Vomiting blood, material that looks like coffee grounds, or black or bloody stools
• Persistent vomiting

If you have chest pain with these symptoms or any emergency, call 911 or go to the nearest emergency department. See your physician promptly for unplanned weight loss, or for heartburn that is frequent, getting worse, or not controlled by medicine.
