When does Nausea occur?
Causes
- Motion sickness or seasickness
- Early stages of pregnancy (nausea occurs in approximately 50%-90% of all pregnancies; vomiting in 25%-55%)
- Medication-induced vomiting
- Intense pain
- Emotional stress (such as fear)
- Gallbladder disease
- Food poisoning
- Infections (such as the “stomach flu”)
- Overeating
- A reaction to certain smells or odors
- Heart attack

The timing of the nausea or vomiting can indicate the cause. When appearing shortly after a meal, nausea or vomiting may be caused by food poisoning, gastritis (inflammation of the stomach lining), an ulcer, or bulimia. Nausea or vomiting one to eight hours after a meal may also indicate food poisoning. However, certain food- borne bacteria, such as salmonella, can take longer to produce symptoms.
