Enrollment: 20
Study Start Date: November 2012
Study Completion Date: June 2013
Primary Completion Date: June 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Colesevelam Drug: Colesevelam
Colesevelam 3750 mg dissolved in 100 ml saline, administered in a feeding tube at time = 0.
Experimental: Chenodeoxycholic acid Drug: Chenodeoxycholic Acid
1.250 mg dissolved in 100 ml saline, administered in a feeding tube at time = 0.
Experimental: Colesevelam + chenodeoxycholic acid Drug: Colesevelam 3750 mg + chenodeoxycholic acid 1250 mg
Colesevelam and chenodeoxycholic acid dissolved in 100 ml saline, administered in a duodenal tube at time = 0.
Experimental: Placebo Other: saline
100 ml saline

Detailed Description:
The investigators hypothesize that even modest increments in endogenous GLP-1 secretion will elicit important antidiabetic effects of GLP-1. To evaluate whether bile acids have such effects, the investigators plan to perform intraduodenal infusion of two different bile acids and placebo.
