A Pharmacy-based Study to Learn More About How Well Iberogast Works, How it Affects the Body, How it is Used, and User Satisfaction in Patients With Functional and Motility-related (Stomach and Bowel Movement-related) Gastrointestinal Diseases, Including Irritable Bowel Syndrome

Study Overview
=================
Brief Summary
-----------------
Researchers want to learn more about the day-to-day use of Iberogast in people who have functional and motility-related gastrointestinal (stomach and bowel) diseases. Functional and motility-related stomach and bowel diseases are conditions in which the functionality of the gut, mainly the gut muscles or the gut/brain axis is disturbed. Functional and motility related stomach and bowel diseases cause symptoms like heartburn, cramps and u pain of the upper and middle part of the belly, also known as functional dyspepsia (FD), and irritable bowel syndrome (IBS). IBS affects predominantly the lower digestive system and causes symptoms like pain of the belly, cramps, bloating, diarrhea, and constipation. In this study, the researchers want to learn more about Iberogast, a plant-based treatment. Iberogast is available to treat stomach and bowel diseases such as FD and IBS. Earlier studies with Iberogast have shown how well it works and how it affects the body. But, little is known about the day-to-day use of Iberogast and how satisfied patients are who take it. So in this study, the researchers want to learn more about Iberogast including: how well it works in day-to-day use how it affects the body, also referred to as tolerability how it is used day-to-day how safe it is how satisfied patients are who take it To answer these questions, the researchers will collect information from pharmacies in Germany. Patients who get Iberogast from these pharmacies to help treat their gastrointestinal disease will complete a questionnaire before, during and after taking Iberogast. The researchers will use the results from the questionnaires to learn more about: the disease details of the patients who are taking Iberogast the patients' symptoms while taking Iberogast if the patients' symptoms change after taking Iberogast how satisfied patients are with Iberogast if the patients had adverse events An adverse event is any medical problem that a participant has during a study. This study will include patients in Germany who: have functional stomach and bowel symptoms or disorders like FD or IBS take Iberogast to treat symptoms of their stomach and bowel disease are able to complete the questionnaire There will be no required tests or visits with a study doctor in this study. No treatments will be given as part of this study. The researchers will review information collected from patients who have decided for their own or by recommendation of their doctors or pharmacist to take Iberogast. The researchers will collect the results from the patient questionnaires from November 2017 to March 2018.
