What Gastric Alimetry?

Gastric Alimetry, also known as body surface gastric mapping, is a breakthrough, non-invasive test used to diagnose functional gastric disorders. Available at our clinics in Manchester, Cambridge and London, the test gives healthcare professionals a more accurate picture of what’s happening in the stomach. This can allow certain causes to be ruled out in favour of others.

How it works

A sticky patch is applied to the surface of your abdomen, where it senses and collects signals for 30 minutes while your stomach is empty.

You'll be given a light meal, then we have 4-hours of post-meal recordings to see how your stomach responds to food. You'll sit comfortably in a recliner chair, free to read, watch a movie, use a device or get out of the chair for a comfort break.

You'll be prompted every 15 minutes to update your symptoms on the app. This will provide real-time symptom changes for your clinician to interpret.

The report will be sent to both you and your referring consultant/doctor, who will explain the results to you in a follow-up consultation.
