The Effect of Sugar Load in IBS Patients Depending on Sucrase-isomaltase Genes
Comparison of Sugar Load Between Normal and Functional Variants of Sucrase-isomaltase Genes in IBS
Study Overview
Status
Intervention / Treatment
Detailed Description
The investigators have in a previous study included IBS patients for treatment with a starch- and sucrose reduced diet (SSRD). The investigators found a great improvement of symptoms. The investigators gene-tested those patients, and now have the full identification of all functional variants encoding sucrase-isomaltase enzymes.
The investigators will invite patients from this previous study with normal genes and functional variants of genes. The patients will come fasting over night to the department of clinical research. The participants will ingest 75 g sugar dissolved in 0.8 dl water and flavored with lemon, to ingest during 5 minutes. After that, glucose will determined repeatedly up to 2 hours afterwards. At the same time, the participants have to assess their gastrointestinal sympotms on visual analogue scales (VAS).
The investigators will compare the raise in b-glucose and symptoms between the groups of patients, divided into gene expression.

Measure Description |
Time Frame |
---|---|---|
Changes from baseline of blood glucose levels
Time Frame: From distribution repeatedly up to 2 hours
|
Measurement of glucose levels in blood drawn from an intravenous needle and analyzed at the Department of Clinical Chemostry
|
From distribution repeatedly up to 2 hours
|
Change from baseline of gastrointestinal symptoms
Time Frame: From baseline and up to 2 hours, at the same time points as blood glucose is measured
|
Measurment of gastrointestinal symptoms on a visual analog scale measuring symptoms, range 0-100 mm, repeatedly at the same time points as blood glucose is measured.
The higher scores, the worse symptoms.
