How to cure Norovirus flu

The very first thing to do when suffering from this flu is to avoid dehydration caused by diarrhea and vomiting. It is therefore essential to drink plenty of water, perhaps in small sips but without ever neglecting this aspect. Medical treatments vary from person to person and can only be prescribed by the attending physician.

These will be associated with rest, the consumption of light foods and, if prescribed, the use of drinks capable of replenishing the lost mineral salts. Based on the extent of the vomiting episodes, the doctor may subsequently decide to prescribe lactic ferments to help the body recover and to safeguard the microbiota.

In general, therefore, it is important to stay at home, drink a lot and obviously only natural water, light teas and, for those who feel like it, some light broths. As far as food is concerned, the consumption of lean meat, complex cereals such as rice or toasted bread, potatoes and Parmesan is recommended.
