Jejunal Ketogenesis and Type 2 Diabetes

NCT05767177 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 12

No results posted yet for this study

Summary

The goal of this cross-over study in obese subjects is to learn about the common co-morbidity type 2 diabetes and the local formation of ketone bodies. The type of study is an exploratory trial with the participants as own controls. The main questions it aims to answer are: 1. Does food intake-induced ketogenesis exist in the small intestine of obese individuals? 2. Are insulin resistance, the incretin GLP-1 release and the glucose transporter SGLT1 affected in obese individuals without type 2 diabetes in the same way as those with type 2 diabetes?

  • Incretins

Interventions

OTHER

Glucemia following Mixed Meal Test

On day 12 of each diet, a venous catheter is placed in one arm for blood sampling and the research person must answer questions about any gastrointestinal complaints in connection with the current diet. At approximately 09:00, the research subject may eat a brunch for approximately 15 minutes (sandwich, juice, fried egg and sausage; 550-600kcal). Venous blood samples are taken before and 15, 30, 45, 60, 90 and 120 minutes after the meal.

OTHER

Enteroscopy - mucosal ketogenic activity as well as glucose transport

On day 14 of each diet period, an enteroscopy is performed. This step is performed to obtain samples (biopsy) of the mucosa of the small intestine (duodenum and jejunum) and is performed at the Gastro-endoscopic departments SU-Sahlgrenska, or SU-Eastern hospital. Endoscopy is experienced by some individuals as unpleasant, which is why local anesthesia and sometimes sedation (midazolam + pethidine or rapifen) can be offered according to standard routine in the endoscopy department.
