Gastroparesis

What is Gastroparesis?

Gastroparesis is a chronic condition in which the stomach empties slowly in the absence of a physical blockage. Delayed emptying is confirmed by testing, and symptoms are generally present for at least three months.^[1]

Common symptoms

The main symptoms are nausea, vomiting, bloating, feeling full after a few bites (early satiety) and upper abdominal pain.^[1] Some people also lose weight or become dehydrated when vomiting or poor intake continues, and symptoms often overlap with functional dyspepsia.^[1]

Causes and risk factors

Most cases are idiopathic, meaning no cause is found, but diabetes is the best-known identified cause.^[1] A meta-analysis estimated that about 9 percent of people with diabetes have gastroparesis, although the authors noted high variability between studies.^[2] Other recognized contributors include abdominal surgery and some medications such as opioids.^{[1, 3]}

The stomach's emptying depends on nerves, pacemaker cells and smooth muscle working together, and damage to any of these can slow it.^[1] Research on stomach tissue also points to oxidative stress and inflammation as part of the cause.^[3]

How it is diagnosed and treated conventionally

Diagnosis needs a gastric emptying test, usually a timed scan after a meal, because symptoms alone cannot separate gastroparesis from other conditions.^{[1, 4]} Your doctor may also rule out a blockage or other causes of similar symptoms.

Treatment starts with changes in what and how you eat, then medicines for nausea and to speed emptying. Treatment is often limited by side effects and by medicines that lose effect over time, and newer endoscopic procedures are used in some people.^{[1, 4]} Nutritional measures include smaller meals, changing the texture of foods and, when needed, liquid meals or tube feeding.^[5]

Why Gastroparesis calls for a whole-person approach

Gastroparesis rarely has a single cause. Nerves, muscle, blood sugar, medicines and the gut's immune activity can each play a part, so symptom control often needs more than one kind of support.^[1]

Complementary care cannot treat the underlying disease. It can be one part of a plan that also covers nutrition, blood sugar and symptom relief.

The vagus nerve and stomach pacemaker cells

The stomach's contractions are coordinated by the nervous system and by pacemaker cells in the stomach wall.^{[1, 3]} Many acupuncture studies are built around the idea that stimulating certain points influences this nerve control, which is discussed below.

Blood sugar

In diabetic gastroparesis, unpredictable emptying makes blood sugar harder to manage, and the two problems can feed each other. A review of dietary trials in diabetic gastroparesis suggested that personalized diet care may help both emptying and blood sugar, though the evidence was limited.^[6]

Inflammation and oxidative stress

Biopsies from people with gastroparesis show increased inflammatory immune cells and signs of oxidative stress in the stomach wall.^[3] In a 2025 study of diabetic rats, electroacupuncture reduced inflammatory infiltration in the stomach muscle, but this has not been shown in people.^[7]

Nutrition and medicines

Poor intake raises the risk of malnutrition, and food texture, fat content and meal size all matter.^[5] Some medicines, opioids among them, can slow the stomach.^[1] Your prescriber should review these.

Acupuncture for Gastroparesis

What the research shows

Acupuncture may reduce symptoms of gastroparesis, but the evidence is weak. A Cochrane review of 32 trials with 2,601 participants, almost all in diabetic gastroparesis, found very low-certainty evidence that more people improved with acupuncture than with prokinetic drugs, and that acupuncture added to usual treatment helped more than usual treatment alone. The review warned about bias, publication bias and incomplete reporting of harms.^[8] Its one sham-controlled trial with a validated symptom scale found low-certainty evidence of no difference between real and sham acupuncture.^[8]

Other meta-analyses point the same way and carry the same limits. One found a higher response rate and better dyspeptic symptoms than controls, but no difference in solid-food emptying.^[9] A review of 59 trials of acupuncture, moxibustion and acupoint massage in diabetic gastroparesis found better effective rates, with low quality and high risk of bias.^[10] An overview of ten systematic reviews rated their methods as low or extremely low quality and concluded the findings cannot be considered reliable.^[11]

For gastroparesis after surgery, a meta-analysis of 15 trials found benefit when acupuncture was added to drug treatment after abdominal surgery, but not after chest surgery, where only one trial was available.^[12]

Small controlled studies exist. In a crossover study, 21 patients with diabetic gastroparesis who completed treatment had greater reductions in stomach retention and symptom scores after one week of real acupuncture than after sham.^[13] A three-center trial of 99 patients found that which points were used affected symptom scores.^[14]

How acupuncture may work

Researchers propose that stimulating points such as ST36 on the lower leg acts through the vagus nerve to improve stomach contractions. In diabetic rats, electroacupuncture improved the stomach's electrical rhythm and emptying, and the effect appeared to depend on vagal pathways.^[15] A 2025 rat study found that the benefit was lost when the vagus nerve was cut.^[7] These are animal findings and proposed explanations, not proof of how it works in people.

What treatment involves

Treatment uses fine, sterile, single-use needles, usually at points on the abdomen, wrist and lower leg, left in place for about 20 to 40 minutes. The three-center trial gave 30-minute sessions on 5 days a week for three weeks.^[14] We reassess after a short course of visits.

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.^[16] Tell the practitioner first if you have a bleeding disorder, take blood thinners, are pregnant, or have a pacemaker or implanted gastric stimulator (relevant to electroacupuncture).

Ayurvedic medicine for Gastroparesis

The Ayurvedic view

Ayurveda does not have an exact equivalent of gastroparesis. Slow digestion with fullness, nausea and bloating is traditionally described as weak digestive fire (mandagni) with a build-up of undigested material (ama), often linked to a disturbed Vata that governs movement in the gut. These are traditional frameworks, not biomedical diagnoses.

Therapies that may be used

Care is chosen for the individual and traditionally combines:

• Small, warm, easily digested meals at regular times, in line with the diet advice your physician or dietitian gives, since meal size and texture matter in gastroparesis^[5]
• Gentle digestive spices and teas in food, chosen with attention to your medicines
• Abdominal oil massage and stress-reducing routines such as breathing practice
• Herbal preparations prescribed individually, from tested sources because some Ayurvedic products contain heavy metals^[17]

Panchakarma procedures, especially emetic or purgative therapies, are not appropriate for people with gastroparesis, who may already be malnourished, dehydrated or on several medicines. They are also not appropriate in pregnancy, acute illness or frailty.

What the research shows

We found no clinical trials of Ayurvedic treatment for gastroparesis in PubMed. Searches on turmeric, ginger, triphala and amla with gastroparesis found animal studies but no clinical trials, so these cannot be presented as treatments. What we offer under this heading is supportive care for general symptoms such as stress and poor appetite, and it is not a treatment for delayed emptying.

Herbal medicine for Gastroparesis

Herbs and formulas that have been studied

Most research is on Chinese herbal formulas, especially Xiangsha Liujunzi decoction, used in trials for diabetic gastroparesis.^[18]

What the research shows

The evidence is limited. A systematic review of 10 trials with 867 patients found Xiangsha Liujunzi decoction outperformed prokinetic drugs on a clinical effective rate. The authors rated the trials' methodological quality as generally low, called the evidence weak, and noted that only two trials reported adverse events.^[18] A review of complementary treatments for diabetic gastroparesis likewise said that the mechanisms were rarely investigated and randomized trials were needed.^[19]

In that review every control group received a prokinetic drug rather than a placebo, and the trials were of low quality, so the results do not show that an herb works as well as or better than standard treatment.^[18]

Safety and herb-drug interactions

Herbs can interact with medicines. Case reports describe bleeding when warfarin was combined with herbs including dan shen, dang gui, ginger and Boswellia.^[20] People with diabetes should also have any herb reviewed against their glucose-lowering medicines, and anyone taking metoclopramide, erythromycin, antidepressants or immunosuppressants should have a prescriber review it first.

About one fifth of Ayurvedic products bought online contained detectable lead, mercury or arsenic.^[17] Herbs should come from tested sources and be prescribed individually. Tell us if you are pregnant or breastfeeding, have liver or kidney disease, or have surgery planned.

Translating traditional medicine into modern biological language

This is interpretation, not equivalence. Chinese medicine often describes gastroparesis-type symptoms as weak spleen and stomach qi, with stomach qi failing to descend, so that food is retained and nausea and vomiting follow. Researchers studying acupuncture look at things that loosely parallel this picture: vagal nerve activity, gastric slow-wave rhythm and pacemaker cell function.^{[7, 15]}

Ayurveda's weak agni and ama describe slow, incomplete digestion with fullness and nausea. No study has shown that these concepts correspond to a specific biological process.

How this care fits with your medical care

Integrative care for gastroparesis is complementary. For a condition like this, we ask that you are under a physician's care for it and that your treating team knows you are receiving complementary care. Do not stop or change prescribed medicines or your diet plan without your prescriber or dietitian.

We do not diagnose gastroparesis or its cause, and new or changing symptoms should be medically evaluated. Please bring your diagnosis, gastric emptying results, a full list of medicines and supplements, and your recent blood sugar records if you have diabetes.

When to seek urgent medical care

Persistent vomiting and poor intake can lead to dehydration and serious complications, so these symptoms need medical attention.^[1]

• Vomiting that you cannot stop, or inability to keep down liquids or medicines
• Signs of dehydration such as dizziness, very dark urine or little urine
• Severe or worsening abdominal pain or a swollen, hard abdomen
• Vomiting blood or material that looks like coffee grounds, or black stools
• Unplanned weight loss, or blood sugar that is very high or very low in a person with diabetes

If any of these occur, call 911 or go to the nearest emergency department.
