Signs and symptoms of IBC

Gastroenteritis is irritation and inflammation of the stomach and intestines, often causing a sudden change in bowel movements with nausea or vomiting. People with gastroenteritis may also have cramping, fever, tiredness, and little interest in food. The illness can spread between people, while contaminated food or water can be another source.

Fluid loss is the main concern, especially when vomiting and diarrhoea happen together. Dehydration may show as a dry mouth, dizziness, unusual sleepiness, or passing much less urine. Rotavirus infection is one possible cause, but symptoms do not identify the germ by themselves.

Take frequent small sips of water or an oral rehydration drink, particularly after loose stools or vomiting. Rest, eat small amounts when able, and wash hands carefully after using the toilet and before preparing food. Avoid preparing food for other people while unwell. A pharmacist or clinician can advise on suitable medicines, especially for children, older adults, pregnancy, or long-term conditions.

Seek urgent care for severe dehydration, fainting, confusion, blood in vomit or stool, severe abdominal pain, breathing difficulty, or an inability to keep fluids down. Prompt assessment is also needed for a very young child, a frail older person, or anyone with a condition that makes fluid loss more risky. Fever with worsening symptoms should not be ignored.

How can I replace fluids safely? Could a medicine or infection explain these symptoms? What signs show that dehydration is developing? When can I return to work, school, or food preparation?
