๐ Quick Summary
Food poisoning is caused by contaminated food, while gastroenteritis is a broader infection of the stomach and intestines, often caused by viruses or bacteria.
1๏ธโฃ Introduction
Food poisoning and gastroenteritis are often confused because they affect the stomach and cause similar symptoms.
However, they are not exactly the same.
Food poisoning usually comes from contaminated food, while gastroenteritis refers to inflammation of the stomach and intestines caused by infection.
Understanding the difference helps you identify the cause and manage symptoms properly.
2๏ธโฃ How the conditions develop
Food poisoning
Occurs when contaminated food introduces harmful bacteria, viruses, or toxins into the body.
Gastroenteritis
Occurs when the stomach and intestines become inflamed due to infection, often viral (such as norovirus) or bacterial.
It can spread from person to person or through contaminated food and water.
