Does a GP consultation treat giardiasis?

Giardiasis is an intestinal infection that may cause watery diarrhoea, stomach cramps, bloating, nausea and tiredness. A GP will ask about your symptoms, recent travel, drinking water, food exposure and whether anyone close to you is unwell. A stool sample may be requested because several bowel conditions can cause similar symptoms. Treatment depends on the assessment and may include a prescription medicine that targets the parasite. The consultation also helps identify dehydration and people who may need closer monitoring.

Drink frequent small amounts of fluid and consider an oral rehydration solution if diarrhoea has been heavy. Wash hands carefully after using the toilet and before preparing food, and avoid preparing food for others while symptoms continue. Keep a note of how often you pass stool, any vomiting, and medicines you take. Take prescribed treatment exactly as directed, even if bowel symptoms improve. Ask the GP when it is safe to return to work, school or childcare, especially if you handle food or care for vulnerable people.

Seek urgent medical help for severe or worsening abdominal pain, fainting, confusion, inability to keep fluids down, very little urine, blood in the stool or marked weakness. Babies, older adults, pregnant people and anyone with a weakened immune system can become dehydrated more quickly and should seek advice promptly. If diarrhoea continues or returns after treatment, arrange a further review rather than repeating leftover medicine.

Ask whether a stool test is needed, which treatment is suitable, how to prevent passing the infection to household members, and when follow-up is needed.
