There are three main types of stomach infections, also known as gastrointestinal infections.
Types of Stomach Infections
Gastrointestinal infections, affecting the stomach and intestines, can be broadly categorized into three primary types based on their causative agents:
-
Bacterial Infections: These infections are caused by bacteria like E. coli, Salmonella, and Campylobacter. They can lead to symptoms such as diarrhea, vomiting, abdominal pain, and fever.
- Example: Food poisoning from contaminated food.
-
Viral Infections: Viruses, such as norovirus and rotavirus, are common causes of stomach infections. They typically result in symptoms similar to bacterial infections but may also include body aches.
- Example: The "stomach flu."
-
Parasitic Infections: These infections are caused by parasites, like Giardia and Cryptosporidium, that enter the body through contaminated food or water. They can result in prolonged diarrhea, nausea, and other gastrointestinal issues.
- Example: Traveler’s diarrhea due to contaminated water.
Common Symptoms of Stomach Infections
While the specific symptoms can vary based on the type of infection, some common symptoms include:
- Nausea

How Infections are Transmitted
These infections are often spread through:
- Consuming contaminated food or water
- Direct contact with an infected person
- Poor hygiene practices
