The Clinical Evaluation of Probiotics Product in Patients With Various Functional Bowel Disorders and Helicobacter Pylori Infection

People nowadays tend to have irregular diet and routine due to the stress at work. This condition may cause intestinal microflora imbalance, and in the long term may lead to constipation, diarrhea, gastroenteritis, gastric ulcer and other gastrointestinal diseases. Helicobacter pylori infection, which can trigger gastrointestinal inflammation and ulcer, is commonly treated by antibiotics. This treatment, however, can reduce the diversity of the intestinal microflora, causing diarrhea, flatulence and nausea. Clinical trials showed that probiotics and prebiotics supplementation could regulate gastrointestinal function, including alleviating constipation, ameliorating antibiotic-associated diarrhea and flatulence, enhancing the effect of H. pylori treatment, and restoring the balance of intestinal microflora. This Probiotics product is a supplement containing several types of probiotics and prebiotics which has been marketed for years. This project aims to observe the effectiveness of Probiotics product consumption by H. pylori-infected patients in relieving the gastrointestinal symptoms and restoring their intestinal microflora.
