Constipation | A Study to Evaluate the Effects of a Natural Supplement in Adults With Chronic Functional Constipation
Constipation research study
What is the primary objective of this study?
Constipation is common in the general population, especially in women and in the elderly. Hard stool is a complaint often associated with constipation, which suggests that stool softening would provide a major benefit in the strategy of treatment. This investigative fibre product is primarily a soluble dietary fibre with added probiotics and a prebiotic. It is not digested in the small intestine and partly remains undigested by bacteria in the gut. Also, as probiotics are believed to help restore a healthy gut flora, reduce pH, assist with digestion of food and reduce gaseous by-products they may aid the improvement of intestinal motility. The objective of this study is to assess if this investigative, fibre product effects the number of bowel movements per week and if this in turn impacts quality of life and symptoms of constipation.
