Name of Study:
Gut Hormones in Addiction (GHADD)
What does the study involve?
We are investigating the effects certain gut hormones (hormones that are produced in the stomach and intestine) have on eating and addictive behaviours in people who are overweight, or have recently stopped smoking or drinking alcohol (or planning to do so in the near future). Previous studies have shown that these gut hormones not only control our appetite and food intake, but may also alter the craving for alcohol and drugs.
We are interested in how these hormones affect brain functioning in people that have recently given up alcohol or cigarettes. This could give us important information about how the hormones affect relapse to alcohol and cigarettes, and have the additional benefits of preventing weight gain.
We will investigate the effects of these hormones through their infusion via a cannula in your arm while you undergo an MRI scan and do some simple computer tasks. You will also complete some questionnaires and have blood taken.These hormones have been used in many medical research studies before and are safe.
The GHADD study is funded by the Medical Research Council (MRC) of the United Kingdom and will take place at the Hammersmith Hospital at Imperial College London. The GHADD study has been ethically approved by the London-Central Research Ethics Committee: 15/LO/1041.
You will receive payment for your time and travel expenses if you are eligible and decide to participate in the GHADD study.
