Research Centre: Faculty of Health and Medical Sciences – The University of Adelaide
Location: Corner of North Terrace and George Street, Adelaide, SA, 5005, Australia
Lead Researcher: Professor Karen Jones
Ethics Committee: This study has been reviewed and approved by the Central Adelaide Local Health Network Human Research Ethics Committee


An excessive drop in blood pressure after a meal, known as postprandial hypotension (PPH), is common among older people and people with diabetes. Currently, there is no satisfactory treatment for this condition. 

This study aims to investigate  the effects of a gut hormone, glucose-dependent insulinotropic polypeptide (GIP), on the rate of stomach emptying, changes in blood pressure, blood sugar levels, blood flow to the gut and oral sugar absorption in healthy older adults. Understanding the role of GIP in PPH will allow researchers to introduce better therapies for this condition. 

Interested participants must be between the ages of 65 to 80 years old. They must be generally healthy. Participants must comply with all the study requirements for over approximately 5-6 weeks.
