Gastric Alimetry is an FDA-cleared system that combines gastric electrophysiology with real-time symptom profiling, providing a clear phenotype to help guide diagnosis.

Non-invasive, radiation-free Body Surface Gastric Mapping.

Layered insights with recorded gastric electrophysiology, real-time symptom profiling, and Gut-Brain Wellbeing data.

A comprehensive automated report on gastric function, symptom burden, and clinical phenotype, to help guide clinical decisions.

Indicated for:
Gastroparesis
Reflux
Chronic Nausea & Vomiting Syndromes
Functional Dyspepsia
Abdominal pain
Cyclical Vomiting Syndrome
Chronic bloating
Foregut surgical evaluation
Postprandial discomfort
How it works

A comprehensive diagnostic report.

Gastric Alimetry reports are automatically delivered within 30 minutes of the test. Resources are available to quickly upskill on report interpretation. The report includes:

Gastric function: whether electrophysiology is normal or abnormal, against validated normative values.

Symptom correlation: how symptoms track with physiological activity, pointing toward motility vs. sensory pathways.

Gut-Brain Wellbeing: additional mental health context.

Gastric Alimetry Phenotypes

Phenotypes to guide clinical planning.

Classify patients into clinically meaningful phenotypes that point to the root cause of symptoms.

Abnormal gastric function

Points towards a motility-based care pathway.

Normal Gastric Function

'Normal' doesn't mean no answer. It helps eliminate motility causes and points towards a sensory-based care pathway.

Disclaimer: Phenotype information is provided for use in aiding the diagnosis of  various gastric disorders.
Clinical Evidence

Grounded in evidence.

Backed by 50+ peer-reviewed publications in leading gastroenterology journals worldwide.

Gastric Alimetry in CNVS

This study evaluated 43 adults with nausea and vomiting syndromes (NVS) and 43 healthy controls using Gastric Alimetry Body Surface Gastric Mapping (BSGM). NVS patients showed an impaired response to meals, and two subgroups emerged despite overlapping symptom profiles: most (62%) recorded normal BSGM alongside higher psychological scores, while a smaller group (31%) recorded abnormal BSGM that correlated with symptom severity. These findings suggest BSGM may add objective physiological information to the clinical assessment of gastric symptoms. Refer article for full COI

Gastric Alimetry Reference Ranges

This study established normative reference intervals for the Gastric Alimetry spectral metrics using results from 110 healthy adults. It defined normal reference ranges for Principal Gastric Frequency (2.65–3.35 cpm), Gastric Alimetry Rhythm Index (≥0.25), BMI-Adjusted Amplitude (22–70 µV), and Fed:Fasted Amplitude Ratio (≥1.08). These normative reference intervals can be used to aid in the assesment of various gastric disorders. Refer article for full COI

Alimetry Patient Profiling

In this multicenter prospective study, body surface gastric mapping (BSGM) with Gastric Alimetry was used to develop and apply a standardized classification scheme in 210 patients with functional dyspepsia and chronic nausea and vomiting syndromes. Most patients (83%) could be classified, and 37.6% showed a spectral abnormality. The identified groups correlated with symptom severity, quality of life, and psychological measures, supporting BSGM as an objective, mechanism-based aid to classifying and diagnosing gastric disorders.

FAQs

Answers to common questions about Gastric Alimetry, testing, and bringing it into your practice.

What is Gastric Alimetry and how does it work?

Gastric Alimetry is 'like an ECG for the stomach'. It is a non-invasive diagnostic tool that measures gastric myoelectrical activity using a wearable device and advanced analytics. It consists of a disposable adhesive patch (Array) containing 64 electrodes placed on the abdomen, a reader to capture data, and a validated app to record patient-reported symptoms. The test integrates this data to generate a comprehensive report on gastric function, which can help clinicians diagnose chronic gastric disorders.

How is Gastric Alimetry different from other gastric tests?

Gastric Alimetry provides unique insights undetected by other diagnostics:

  • It evaluates gastric electrophysiological function.
  • It is non-radioactive and non-invasive.
  • It integrates real-time symptom profiling and gut-brain wellbeing data, offering a holistic view of the patient's condition.
  • It provides FDA-cleared phenotypes to differentiate between a motility vs sensory issue.

Is Gastric Alimetry FDA cleared?

Yes. Gastric Alimetry has been cleared for use in the US since 2022. Gastric Alimetry is also available for use in the UK, New Zealand, and Australia.

Is the test reimbursable through insurance?

Gastric Alimetry has the CPT III code 0868T in the US. Outside the US, coding and reimbursement pathways vary by country. Our market access team works directly with your billing or reimbursement department to support a smooth process wherever you are located.

‍

Are there any considerations or contraindications?

Gastric Alimetry should not be used in patients who:

  • Have life-threatening conditions that could result in immediate danger.
  • Are unable to remain seated comfortably for the duration of the test.
  • Have open wounds, abrasions, or inflamed areas on the abdomen.
  • Have fragile skin prone to tearing, as removing the adhesive array could cause irritation or tearing.

Which patients are appropriate for testing?

The test is ideal for patients 12 years and over who are experiencing persistent symptoms and multiple therapy failures. Those with chronic nausea and vomiting, with or without an existing diagnosis of gastroparesis, severe functional dyspepsia, or other vomiting diagnoses (including cyclical vomiting syndrome). It is also ideal for evaluation of other chronic gastric symptoms such as bloating, abdominal pain, reflux, and postprandial discomfort. It can be used early in the diagnostic pathway to determine whether gastric function is normal or abnormal, guiding subsequent care decisions.

How do I bring Gastric Alimetry into my practice?

Get in touch using the form and a member of our team will be in contact to walk you through the process.

My patient has a PEG tube/other invasive nutritional support. Can they still have a Gastric Alimetry test?

Yes, you can run the Gastric Alimetry test on a patient with a percutaneous enteral feeding (PEG/PEGJ/PEJ) tube. If the patient has a gastric feeding tube, the Array can be carefully cut to allow accurate placement around the tube. The Alimetry team are available to support you with this if needed.
