Gastrointestinal Infections
Overview
Gastrointestinal infections affect the digestive tract and are commonly caused by bacteria, viruses, parasites, or contaminated food and water. These infections may range from mild digestive upset to more serious illness requiring medical treatment or monitoring.
Symptoms often develop suddenly and may affect hydration, nutrition, and overall wellbeing. While many infections improve with supportive care, persistent symptoms or severe dehydration should be assessed early.
The goal of care is to identify the cause of infection, support recovery, and reduce complications.
Symptoms
Symptoms can vary depending on the type and severity of infection. You may experience:
- Diarrhoea or loose stools
- Abdominal pain or cramping
- Nausea or vomiting
- Fever or chills
- Bloating or digestive discomfort
- Weakness or dehydration
Some people may also experience loss of appetite or fatigue.
