What is vomiting?
Vomiting can happen for many different reasons. It may be caused by a viral infection. Food poisoning can also cause vomiting. These often cause diarrhoea as well. Vomiting can also be caused by an illness or pregnancy.
Vomiting in adults is usually not a sign of anything serious and usually improves within 48 hours (two days) and may have completely gone within three days.
It can occasionally be a sign of something more serious.
Visit your doctor if:
- The vomiting lasts for more than 2 days
- You have had bouts of nausea and vomiting over the last month
- You are losing a lot of weight
- You think you may be getting dehydrated.
Vomiting can be unpleasant and you may find you feel unwell for a few days after you have been sick.
