Summary

The study aim is to investigate the Bio-electrical Impedance (BIA) parameters in general, and phase angle (PhA) in particular in Irritable bowel syndrome (IBS) patients and to compare these with values from healthy controls, while assessing the relationship with other confounding parameters in IBS: psychological parameters, physical activity, dietary pattern (with special interest in FODMAP intake). In a second phase, the evolution of the BIA parameters will be analyzed according to response to therapy.

Conditions

  • Irritable Bowel Syndrome

Interventions

DEVICE

Bio-electrical impedance analysis

Bio-electrical Impedance Analysis will be performed by trained personnel. BIA will be performed after fasting for at least 6 hours. Subjects should refrain from intensive physical activity the day be-fore the measurement. For women, measurements will be performed outside menstruating periods. Subjects will lay down on an examination couch with bare feet. Any jewelry will be removed. Reactance and resistance will be obtained. Phase angle will be calculated according to the formula: PhA (°) = (reactance/ resistance° x (180°/π). Body composition, including muscle mass and percentage body fat will be calculated.
