NCT02879955

Brief Summary

To investigate the secretion of gut hormones, in particular glucagon-like peptide 1 (GLP-1), after ingestion of glucose and fructose as separate monosaccharides or combined in the disaccharides sucrose and isomaltulose and the effect of acarbose in gastric bypass operated subjects and BMI-matched controls.

Outcome Measures

Primary Outcomes (1)

  • Within group difference in GLP-1 secretion (evaluated by iAUC).

    Comparison of the GLP-1 responses (evaluated by iAUC) induced by the different carbohydrate loads.

    0-240 min following carbohydrate ingestion

Secondary Outcomes (11)

  • Between group comparison of GLP-1 secretion (evaluated by iAUC).

    0-240 min following carbohydrate ingestion

  • Between group comparison of differences in GLP-1 secretion (evaluated by iAUC).

    0-240 min following carbohydrate ingestion

  • Responses (evaluated by iAUC) of glucose within and between groups.

    0-240 min following carbohydrate ingestion

  • Responses (evaluated by iAUC) of insulin within and between groups.

    0-240 min following carbohydrate ingestion

  • Responses (evaluated by iAUC) of C-Peptide within and between groups.

    0-240 min following carbohydrate ingestion

  • +6 more secondary outcomes

Study Arms (2)

10 gastric bypass operated patients

EXPERIMENTAL

4 different carbohydrate loads ingested at separate study days will be tested against each others ability to induce GLP-1 secretion.

Other: Glucose + FructoseOther: SucroseOther: IsomaltuloseOther: Sucrose + Acarbose

10 healthy control subjects

EXPERIMENTAL

4 different carbohydrate loads ingested at separate study days will be tested against each others ability to induce GLP-1 secretion.

Other: Glucose + FructoseOther: SucroseOther: IsomaltuloseOther: Sucrose + Acarbose

Interventions

Ingestion of the separate monosaccharides glucose (25 g) and fructose (25 g) dissolved in 200 mL of water. The load provides 0.1385 mol glucose and 0.1385 mol fructose.

10 gastric bypass operated patients10 healthy control subjects
SucroseOTHER

Ingestion of the disaccharide sucrose (47.5 g) dissolved in 200 mL of water. The load provides 0.1385 mol glucose and 0.1385 mol fructose.

10 gastric bypass operated patients10 healthy control subjects

Ingestion of the slowly digestable disaccharide isomaltulose (47.5 g) dissolved in 200 mL of water. The load provides 0.1385 mol glucose and 0.1385 mol fructose.

10 gastric bypass operated patients10 healthy control subjects

Ingestion of the disaccharide sucrose (47.5 g) and the alpha glucosidase inhibitor acarbose dissolved in 200 mL of water. The load provides 0.1385 mol glucose and 0.1385 mol fructose.
