What causes nausea and vomiting?

Nausea and vomiting can be caused by many different factors, but some of the most common ones are:

•  Food poisoning: Food poisoning occurs when you eat food that is spoiled, contaminated or toxic. This can cause nausea, vomiting, diarrhea, abdominal cramps and fever. Some of the common causes of food poisoning are salmonella, E. coli, campylobacter and norovirus. Food poisoning can be prevented by practicing good hygiene, cooking food thoroughly and storing food properly.

•  Motion sickness: Motion sickness is a condition that occurs when your brain receives conflicting signals from your eyes, ears and body about your movement and position. This can cause nausea, vomiting, dizziness and sweating. Motion sickness can be triggered by traveling in a car, boat, plane or amusement park ride. Motion sickness can be prevented by sitting in the front seat or near a window, looking at the horizon, avoiding reading or watching screens and taking medication before traveling.

Pregnancy-induced nausea and vomiting usually goes away by the second or third trimester.
