Sucrase-Isomaltase (SI) Genes and Meal Load

Condition(s) studied

Investigational drug(s) / intervention(s)

Meal load: Meal load during 15 minutes

Study summary

The goal of this interventional study is to examine whether those patients with irritable bowel syndrome (IBS) and a reduced abitility do degrade starch and sugar (lowe levels of enzymes) have lower raise in blood glucose after a meal than those with normal expression of enzymes. We also want to examine whether those IBS patients with reduced enzyme levels have increased bowel symptom in relation to this meal.

The main questions it aims to answer are:

Does reduced ability to degrade starch and sugar due to less enzyme activity lead to lower increase in blood glucose after a meal? Does reduced ability to degrade starch and sugar due to less enzyme activity lead to increased bowel symptoms after a meal?

Eligibility

Primary outcome measure(s)

• Changes of blood glucose after a meal intake — 2 hours
  We will measure blood glucose levels in plasma through a plastic tube. Two samples will be collected before the meal start. One sample 10 minutes before the meal intake and one immediately prior the meal intake. The meal consists of a sugar-rich breakfast, which must be ingested within 15 minutes. Blood samples will then be collected at 10, 20, 30, 45, 60, 90, and 120 minutes afterwards. Blood glucose will be measured at the Department of Clinical Chemistry at the hospital, according to clinical routines.
