Nausea is a very unpleasant feeling in the pit of the stomach. Intense nausea often leads to vomiting, which forces stomach contents up the oesophagus and out of the mouth. Nausea and vomiting may be caused by:
- Viral stomach flu or food poisoning;
- Stress or nervousness;
- Head injury.
If vomiting is severe and persistent, stop all food for several hours or until you are felling better. Take frequent small slips of water or a rehydration drink;
- If vomiting lasts longer than 24 hours, sip a rehydration drink to restore lost fluids and nutrients;
- Rest in bed until you feel better.
