Clinical trials and research studies in oral and gastrointestinal

What are the oral and gastrointestinal systems?

The gastrointestinal system, or the digestive system, is essential for providing the body with the nutrients and energy it needs to stay healthy, and processing and discarding waste. The digestive system breaks down the nutrients in foods and drinks, which are then absorbed by the body for use. The digestive system comprises the Gastrointestinal Tract (GIT) and the liver, pancreas and gallbladder. The (GIT) runs uninterrupted from the mouth all the way through the body to the anus, and includes the oesophagus, stomach, and small and large intestine.

There are many diseases and conditions that can affect the digestive system, some of these last a short time (acute), while others are longer lasting and are considered to be chronic conditions. One condition that affects the digestive system is inflammatory bowel disease (IBD), which is an autoimmune condition which involves inflammation of the digestive tract. There are two types of IBD: Crohn’s Disease, which can affect any area of the GIT, and Ulcerative Colitis which affects the large intestine and rectum. Irritable Bowel Syndrome (IBS) is different to IBD, and is a common condition that affects many people around the world. IBS causes gastrointestinal symptoms such as bloating, diarrhoea, constipation, and abdominal pain, and is not very well understood or diagnosed. Other diseases and conditions of the digestive system can include diseases of the liver (such as hepatitis and fatty liver disease), diverticulitis, haemorrhoids, and reflux.

Where is oral and gastrointestinal research now?

There are many research studies conducted around the world in regards to different areas of the gastrointestinal system, including helping to understand and prevent the development of these diseases and conditions, to predict the later consequences of these diseases and conditions and also to better manage and even treat symptoms. Some of the latest research is investigating methods to reverse damage done to the digestive tract as a result of these diseases and conditions and new therapies to mitigate inflammation, a major component of many digestive system diseases and conditions.

How can I get involved in oral and gastrointestinal research?

Getting involved in research and clinical trials studying the digestive system may be a part of your recovery plan, or it may help pave the way in developing new management interventions or therapies that will benefit others. There are a large number of clinical trials and research studies undertaken each year to understand, manage and treat diseases and conditions of the gastrointestinal system.
