BACKGROUND & AIMS: Patients with irritable bowel syndrome constipation (IBS-C) and patients functional (FC) have similar symptoms, these disorders overlap in their diagnostic features. Little is known about physiology or the involvement of serotonin signaling. We investigated relationships between platelet-depleted plasma concentrations serotonin, gastrointestinal motor-sensory function FC IBS-C compared healthy volunteers (controls). METHODS: We measured fasting fed individuals (n =...
