Severe or worsening pain, a rigid abdomen, fainting, bleeding or persistent vomiting are warning signs.

Sudden severe pain, worsening pain, marked tenderness or rigidity, fainting, breathlessness, blood in vomit or stool, high fever and persistent vomiting require urgent assessment. Pain location alone cannot establish a diagnosis, and self-medicating with painkillers may delay seeking care.
Medical principle
Many digestive symptoms are temporary, but their intensity, duration, pattern and accompanying signs determine whether self-care is enough. Broadly eliminating foods without a diagnosis can cause nutritional deficiencies.
Practical steps that may help
- Record symptoms, foods, medicines and bowel patterns for several days to help identify connections.
- Eat slowly, increase fibre gradually and drink adequate fluids.
- Do not use over-the-counter digestive medicines long term without investigating the cause.
When should you seek medical care?
Bleeding, black stools, persistent vomiting, fever, weight loss, severe or worsening pain, a rigid abdomen, inability to pass gas or dehydration need prompt assessment.
