What type of disorders does gastrointestinal illness encompass?

Gastrointestinal illness specifically refers to a range of conditions that affect the digestive system. This includes any diseases or disorders that impact the functioning of organs such as the stomach, intestines, and other related structures involved in digestion. These illnesses may manifest in various forms, including infections caused by viruses, bacteria, or parasites, as well as inflammatory conditions like gastritis or inflammatory bowel diseases.

The focus on the digestive system is critical because gastrointestinal disorders often present symptoms such as nausea, vomiting, diarrhea, abdominal pain, and changes in appetite, all of which directly relate to how the body processes and absorbs food and nutrients. Understanding these conditions helps health professionals diagnose, prevent, and treat gastrointestinal diseases more effectively, making it essential knowledge for professionals in the field of environmental health and beyond.
