How is gastroenteritis treated?
Depending on the cause, most cases of gastroenteritis are not treated at all, with the main advice being to stay at home and rest until symptoms pass. Taking small sips of clear fluid, if tolerated, throughout the day is recommended. In cases of severe dehydration, hospitalisation is required. Medications are only prescribed in certain situations, depending on the cause. Parasites are treated by anti-parasitic drugs. Some forms of bacteria are treated by antibiotics. In cases of severe vomiting, drugs are sometimes prescribed to stop this (antiemetics). Doctors don't advise taking over-the-counter medications for gastro, as these can make you much worse by keeping infection inside your body.
