- The main immediate risk with frequent diarrhoea is dehydration, especially in children, older adults and people who are already unwell.
- Blood in stool, severe abdominal pain, persistent vomiting, high fever or marked weakness needs medical review.
- TCM or food therapy should not delay investigation when symptoms are severe, persistent or recurring.
Count the practical things
Notice how often stools occur, whether they are watery, whether there is blood or black stool, and whether there is fever, vomiting, travel, sick contacts or recent antibiotics. These details are more useful than simply saying the stomach is “weak”.
Hydration comes first
Small frequent drinks may be easier to tolerate than large amounts at once. Oral rehydration solutions can be useful when fluid and salts are being lost. People with significant heart or kidney disease should follow personalised fluid advice.
Keep food simple without starving
When appetite returns, ordinary foods that are easy to tolerate are reasonable. There is usually no need to fast for long periods or use very restrictive “detox” diets. Avoid alcohol and foods that clearly worsen symptoms while the gut settles.
Be cautious with medicines
Some anti-diarrhoeal medicines are not suitable in certain infections or when there is blood in stool or high fever. Check with a pharmacist or doctor when unsure, especially for children, pregnancy, older adults or people with chronic illness.
TCM should stay complementary
A practitioner may discuss traditional digestive patterns, herbs or acupuncture. If diarrhoea is severe, recurring, associated with weight loss, bleeding or dehydration, medical diagnosis is more important than trying repeated symptom-control treatments.
Know dehydration and emergency warning signs
Seek medical review for very little urine, severe thirst, dizziness, persistent vomiting, blood or black stool, high fever, severe abdominal pain, marked weakness or symptoms that are not improving. Call 995 for life-threatening collapse or severe deterioration.
