Brief summary: In this study, we will evaluate the efficacy of prebiotics combined with quadruple probiotics in the treatment of functional constipation through an open RCT study. The experimental group received lifestyle guidance and combined intervention of prebiotics and quadruple probiotics at the same time. The patients took the combination of prebiotics and probiotics twice a day during the treatment period. The control group received only lifestyle instruction. At the same time, to evaluate the safety of probiotics combined with quadruple probiotics in the treatment of functional constipation, and provide a new treatment plan for clinical treatment of functional constipation.

Detailed description: The purpose of this study is to analyze the intestinal microecology of patients with functional constipation before and after treatment through intestinal microecological intervention, mainly using the combination of probiotics and prebiotics. We will record the patient's stool diary, including bowel movements, stool quality, bowel time, defecation difficulty, emptying sensation, manual operation and medication. At the same time, we will use the Bristol Fecal Traits Scale (BSFS) and the Constipation Patient Self-Rating Scale (PAC-SYM) and Constipation Patient Quality of Life Scale (PAC-QOL) scores completed weekly. In addition, we will monitor indicators of inflammation (IL-1β, IL-6, TNF-alpha) and intestinal barrier function (LPS), neurotransmitter (serotonin, acetylcholine)) to assess constipation improvement in patients with functional constipation.
