GI Physiology

The gastrointestinal physiology unit is located within the Endoscopy department on LG1 at Royal Stoke University Hospital.  The unit is led by an independent practitioner who uses the most up-to-date, highly technical equipment to provide a range of diagnostic procedures on the upper and lower intestinal tract. We also offer a biofeedback service for people with bowel disorders.  

We see in excess of 1000 patients each year, who may be referred because they suffer from any of the following conditions:

  • Difficulty swallowing (dysphagia)
  • Unexplained chest pain
  • Heartburn, indigestion (gastro oesophageal reflux disease)
  • Cough
  • Excessive belching or burping
  • Malabsorption due to small bowel bacterial overgrowth or lactose intolerance
  • Faecal incontinence
  • Constipation
  • Feeling of incomplete rectal emptying
  • Rectal prolapse

The physiology team work as part of a multidisciplinary team which includes Gastroenterologists, Upper GI and Colorectal Surgeons, Radiographers and other healthcare professional,s all of whom discuss patient test results and the care pathway.

Gastrointestinal tests include:

  • Oesophageal high resolution manometry
  • 24 hr ambulatory pH and Impedance monitoring
  • Anorectal high resolution manometry
  • Biofeedback therapy
  • Breath tests to detect for small bowel bacterial overgrowths and lactose intolerance
