The Alimetry System

Gastric electrophysiology. Insight that guides care.

An FDA-cleared system, Gastric Alimetry combines gastric electrophysiology with real-time symptom profiling to help guide your patient's care.

Non-invasive, radiation-free Body Surface Gastric Mapping. A patient-friendly solution for those aged 12 and over.

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

The ability to differentiate patients with a comprehensive report on gastric function and symptom burden.

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 detailed report of gastric function.

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: determine whether gastric activity falls within the normal range using validated adolescent normative intervals.

Symptom correlation: understand how reported symptoms align with physiological activity.

Gut-Brain Wellbeing: gain insight into psychological wellbeing, an important dimension often missed by conventional testing.

Phenotype Compass

Phenotypes to guide clinical planning for patients 12 and over.

Gastric Alimetry classifies patients aged 12+ into clinically meaningful phenotypes. This points you toward a motility or sensory-based pathway, so you can stop guessing and start treating.

Abnormal Gastric function

Points towards a motility-based care pathway.

Normal Gastric Function

'Normal' doesn't mean no answer. It helps eliminate motility issues and suggests a sensory cause.

Clinical Evidence

Grounded in evidence.

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

BSGM in Adolescents

In 25 adolescents with functional dyspepsia or gastroparesis, symptoms, quality of life, and psychological profiles overlapped substantially between the two diagnoses. Body surface gastric mapping (BSGM) using Gastric Alimetry distinguished three phenotypes - BSGM Normal, BSGM Delayed, and Low Stability/Low Amplitude - that symptoms alone did not separate, and these subgroups differed in symptom burden. The findings suggest BSGM can add an objective physiological layer as an aid in assessing gastric disorders. As a single-cohort study, the results warrant confirmation in larger cohorts.

Pediatric Pictograms

Children often struggle to express gastric symptoms in words, which makes accurate reporting complex. This study co-designed 10 symptom pictograms with children and young people, across three phases - cocreation, validation, and preference mapping. The pediatric sets demonstrated significantly superior face validity, content validity, and overall comprehension, particularly among children experiencing more severe gastric symptoms.

Youth Alimetry Gut-Brain Wellbeing Survey

The Alimetry® Gut-Brain Wellbeing Survey-Youth Version (AGBW-Y) is a validated, 10-item questionnaire designed to assess mental health in young people aged 12–17 with chronic stomach symptoms. Co-designed with youth and clinicians, this tool assesses depression, anxiety, and stress without confusing physical illness with psychological distress. Research confirms the survey is highly reliable, valid, and rated as easy for adolescents to complete and understand. The AGBW-Y offers healthcare providers a useful screening aid to help understand a young patient's mental wellbeing.

FAQs

Answers to common questions before you get started.

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.
