This guide is general education, not a diagnosis or an individual treatment plan. Urgent, severe or worsening symptoms belong with the local emergency service or a qualified clinician.
Acute and persistent diarrhoea, hydration and red flags. This source-reviewed orientation page separates stable record-the-onset-pattern-stool-or-vomit-features-food-fluid-medicine-and-associated-symptoms principles from decisions that depend on examination, hydration status, pregnancy, age, immune status, bleeding, obstruction signs, endoscopy, laboratory or physiological testing, exact diagnosis, local prescribing and direct professional assessment.
The named editions, URLs and reuse limits were checked on 2026-09-10. It remains outside search indexes pending a second-person clinical editorial review and localisation.
Start with the description that most closely matches your question about Acute and persistent diarrhoea, hydration and red flags. Use the evidence section to understand what is known, then use the boundary section to decide when self-education should stop and clinical care should begin.
The page keeps the main question, its evidence base and its limits together in one canonical place. That makes it useful as a quick orientation and avoids splitting a broad subject into shallow pages before each narrower answer has enough verified material of its own.
These concise notes are independently written from the source set below. In an emergency, use the local emergency number and follow the dispatcher rather than relying on a static page.
Record start time, frequency, blood or mucus, fever, pain, vomiting, urine, travel, shared meals, antibiotics, new medicines and affected contacts. Many short episodes are infectious, while repeated or chronic diarrhoea has a broader differential and needs an assessment before it is labelled functional. Soap-and-water hand hygiene and avoiding food preparation reduce spread.

Take frequent small drinks and ask a pharmacist about oral rehydration when dehydration risk is higher. Inability to keep fluid down, reduced or dark urine, confusion, bloody stool, severe sudden abdominal pain, green or bloody vomit, or a vulnerable infant, older adult or immune-suppressed person needs prompt local advice. Anti-diarrhoeal medicine is not suitable for every age or cause.
