Key points
- Unlike typical bacterial food poisoning, symptoms from this parasite tend to persist for weeks instead of resolving in days.
- A single dose of one antiparasitic agent or a short multi-day course of another can clear the infection effectively.
- Not everyone infected develops symptoms, and those who do often experience prolonged gut upset and tiredness.
Symptoms and what sets it apart
The infection typically causes persistent, greasy diarrhoea that floats, along with bloating, stomach cramps, nausea, and excessive wind. Fatigue is common. Unlike bacterial food poisoning, giardiasis tends to drag on for weeks rather than days, and some people carry the parasite without noticeable symptoms.
Clearing the infection
Giardiasis responds well to antiparasitic medicines. The most commonly used agents are tinidazole, which is often given as a single dose, and ornidazole, taken over a short course. Albendazole is a broader antiparasitic that is sometimes used where tinidazole-class medicines are unavailable. Staying well hydrated throughout treatment helps the gut recover, especially if diarrhoea has been prolonged.
Symptoms that do not improve after a full treatment course, or that include blood in the stool or a high fever, warrant prompt medical review.
