Fat Metabolites and Gut Hormones
24 juli 2017 uppdaterad av: Christoffer Martinussen, Hvidovre University Hospital
Effects of Fat Metabolites on Gut Hormone Secretion After Gastric Bypass Surgery
To investigate the effects of different fat metabolites on gut hormone secretion in gastric bypass operated subjects and BMI-matched controls.
Studieöversikt
Status
Okänd
Intervention / Behandling
Detaljerad beskrivning
Dietary triglycerides are hydrolyzed during digestion to two fatty acids and one 2-monoacyl glycerol.
The study will investigate the effects of these different fat components on gut hormone secretion in gastric bypass operated patients and non-operated BMI-matched controls.
