Chronic Indigestion (Dyspepsia)

What is Chronic Indigestion?

Chronic indigestion, or dyspepsia, is recurring discomfort in the upper abdomen, such as pain, burning, fullness after eating or feeling full too soon. When imaging and endoscopy show no structural disease, the condition is called functional dyspepsia, which is one of the most common functional digestive disorders.^[1]

Common symptoms

Functional dyspepsia is defined by one or more of epigastric pain, burning, early satiety and postprandial fullness.^[1] It has two main patterns: epigastric pain syndrome, where pain or burning dominates, and postprandial distress syndrome, where meal-related fullness and early satiety dominate.^[2]

• Bloating and belching
• Nausea, which is usually occasional
• Heartburn, which is infrequent in functional dyspepsia^[1]

Causes and risk factors

Several mechanisms are linked to functional dyspepsia, including altered stomach and duodenal movement, a more sensitive gut, low-grade inflammation, past gut infection, disturbed gut-brain signaling and psychological factors.^[2] Other conditions can cause similar symptoms, including stomach inflammation, acid reflux, peptic ulcers, gallbladder problems and medicines such as anti-inflammatory painkillers, which is why evaluation by a physician matters.^[1]

How it is diagnosed and treated conventionally

Diagnosis uses Rome IV criteria and the absence of structural disease on imaging or endoscopy.^[1] Alarm symptoms such as weight loss, trouble swallowing or vomiting call for endoscopy.^[1] Testing is otherwise kept to a minimum because repeat investigations rarely help when there are no alarm features.^[2]

People should be tested and treated for Helicobacter pylori if it is present. Further treatment relies on acid-lowering medicines (proton pump inhibitors and H2 blockers), prokinetic drugs and antidepressants.^[1] Psychological and complementary approaches are also described in reviews.^[2]

Why Chronic Indigestion calls for a whole-person approach

Functional dyspepsia does not have one cause, and the same treatment does not work for everyone. Reviews describe several overlapping mechanisms in the stomach, nerves and brain, which gives a rationale for different treatment approaches.^[2]

Some patients use complementary care alongside medical treatment to address digestion, stress and eating habits together.

Stomach movement and sensitivity

Changes in how the stomach and duodenum move, and heightened sensitivity to stretch and acid, are among the mechanisms listed.^[2]

The gut-brain axis

Disturbed signaling along the brain-gut axis, and psychological factors, are linked to functional dyspepsia.^[2] A review of Chinese herbal trials also frames the condition as a disorder of gut-brain interaction.^[3]

Infection and low-grade inflammation

Past gut infection and micro-inflammation are described as contributors in some people.^[2] Helicobacter pylori testing is part of standard evaluation.^[1]

Diet and daily habits

A survey of 138 patients with non-ulcer dyspepsia in India found most reported frequent spicy, sour, heavy or oily foods, and many reported worry. A survey cannot show that these habits caused the condition.^[4]

Acupuncture for Chronic Indigestion

What the research shows

Acupuncture may relieve functional dyspepsia symptoms, but review-level evidence is low in certainty. In a trial at five hospitals in China, 278 adults with postprandial distress syndrome had 12 sessions over 4 weeks of real or sham acupuncture. At week 4 the estimated response rate was 83 percent with real acupuncture and 52 percent with sham, and the effect lasted through 12 weeks of follow-up. The authors noted limits including a high dropout rate and the inability to blind the acupuncturists.^[5]

A second trial in 200 people with refractory functional dyspepsia found that 20 sessions of real electroacupuncture over 4 weeks gave more adequate symptom relief than sham at 16 weeks (62 percent versus 22 percent). Complete absence of symptoms, the primary outcome, was reached by 17 percent with real and 6 percent with sham electroacupuncture.^[6]

Reviews are more cautious. A Cochrane review of seven trials (542 participants) rated all evidence as low or very low quality and could not reach a firm conclusion.^[7] A 2021 meta-analysis of 61 trials in functional gastrointestinal disorders found better symptom improvement than sham acupuncture or drugs, but rated the evidence as moderate or low.^[8] A 2025 meta-analysis of 29 trials reached a similar conclusion with very low to moderate certainty.^[9] A Bayesian analysis suggested acupuncture combined with Western medicine worked better than Western medicine alone.^[10]

Sham acupuncture itself produced sizable symptom improvements in a pooled analysis of trials, so placebo effects are strong in this condition.^[11]

How acupuncture may work

A systematic review of mechanism studies in people with functional dyspepsia found acupuncture was associated with changes in stomach movement, stomach relaxation after eating, digestive hormones, mood and autonomic nervous system function. The authors said better-designed studies are needed.^[12] These remain proposed explanations.

What treatment involves

Treatment uses fine, sterile, single-use needles placed on the abdomen, limbs and sometimes the back, usually left in place for about 20 to 40 minutes. The two main trials used 12 to 20 sessions over 4 weeks.^{[5, 6]} We reassess after a short course of visits.

In prospective studies, about 9 in 100 patients had a minor reaction such as bleeding, soreness 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 Chronic Indigestion

The Ayurvedic view

Ayurveda describes upper-digestive burning, sour belching and heaviness as Amlapitta, in which Pitta is said to be aggravated and agni, the digestive fire, disturbed. These are traditional categories used to individualize care, not biomedical diagnoses.

Therapies that may be used

Care is chosen for the individual and traditionally combines:

• Regular meal times and smaller meals, with attention to foods that trigger symptoms
• Cooling, less spicy and less oily foods, and rest after meals
• Herbs and formulas prescribed individually by a qualified practitioner
• Stress-reducing routines such as breathing practice and steady sleep hours

Panchakarma is not appropriate during pregnancy, acute illness or frailty, or before warning symptoms have been medically assessed.

What the research shows

The research on Ayurveda for dyspepsia is very limited. We found no placebo-controlled trials. A single-arm study of 30 patients with Rome IV dyspepsia given individualized herbo-mineral preparations for 28 days reported symptom improvement, but with no comparison group the results cannot show the treatment caused the change.^[14] The survey of 138 patients described above supports the traditional emphasis on diet and routine but is not evidence of treatment effect.^[4]

Herbal medicine for Chronic Indigestion

Herbs and formulas that have been studied

Studied Chinese formulas include Xiao Yao Pill and a modified Ban Xia Xie Xin decoction.^[15] Rikkunshito, a Japanese Kampo formula, has been widely studied.^[16] Curcumin, the main compound in turmeric, was tested against the acid-lowering drug omeprazole in a trial in Thailand.^[17]

What the research shows

The evidence is limited. A network meta-analysis of 15 placebo-controlled trials of 12 herbal formulas, rated mediocre quality, found herbal medicine better than placebo for global symptoms at 8 weeks, with no serious adverse events.^[15] A review of 11 trials of Chinese herbal medicine in people with functional dyspepsia and anxiety or depression reported better response rates than placebo or comparison drugs, with limits in study quantity and quality.^[3]

A meta-analysis of 52 trials found Rikkunshito outperformed Western medicine, and its authors called for higher-quality trials.^[16] In the Thai trial of 206 patients, curcumin and omeprazole had comparable effects on symptoms, with no added benefit from combining them.^[17]

Safety and herb-drug interactions

Herbs are active substances and can interact with medicines. Case reports describe bleeding when warfarin was combined with several herbs, including dang gui, dan shen, ginger and Boswellia.^[18] People taking blood thinners need a practitioner's review before using herbs.

In one study, about one fifth of Ayurvedic products bought online contained detectable lead, mercury or arsenic.^[19] Herbs should come from tested sources and be prescribed individually. Tell us if you are pregnant or breastfeeding, have liver or kidney disease, or take acid-lowering or other prescribed medicines.

Translating traditional medicine into modern biological language

The links drawn here are interpretation, not equivalence. Chinese medicine often describes this pattern as liver qi stagnation with spleen and stomach disharmony. Researchers studying acupuncture look at things that loosely parallel this picture, such as stomach movement and accommodation, digestive hormones and autonomic and brain function.^[12]

Ayurveda's aggravated Pitta and weak agni describe burning and poor digestion. No study has shown that a dosha or agni corresponds to a specific biological process.

How this care fits with your medical care

Integrative care for chronic indigestion is complementary. Keep your physician or gastroenterologist, and do not stop or change prescribed medicines, including acid-lowering drugs, without talking to your prescriber. We do not diagnose the cause of indigestion, so persistent or new symptoms should be medically evaluated first.

Please bring your diagnosis, any endoscopy or Helicobacter pylori test results, and a full list of medicines and supplements.

When to seek urgent medical care

Some symptoms with indigestion point to a more serious problem and need prompt medical evaluation.^[1]

• Unintended weight loss
• Trouble swallowing or food sticking
• Repeated vomiting
• Vomiting blood, or black or bloody stools
• Anemia or new symptoms after age 50
• Pain that is severe, constant or spreads to the chest, arm or jaw

If you have severe chest pain, vomit blood, or pass black stools, call 911 or go to the nearest emergency department.
