Causes and Treatment of Diarrhoea:
Acute diarrhoea is often caused by gastroenteritis due to either a viral or bacterial infection. Other causes may include food intolerances, stress or side effects from certain medications.1 Diarrhoea can be inconvenient and disruptive, making symptom relief important so that you can get back to your life with as little interruption as possible.
Treat acute diarrhoea at the first sign of symptoms: Gastro-Stop is the #1 selling brand in Australia for diarrhoea relief2 with two effective solutions that can be tailored towards the sufferer's symptoms.
