What causes nausea and vomiting?

Some of the most common infections that cause nausea and vomiting are colds, flu, ear infections, strep throat, bronchitis and urinary tract infections. These infections can be transmitted through contact with infected people, animals or objects, or through contaminated food or water.
• 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.

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