Nausea is a feeling of queasiness and discomfort in your stomach often with the urge to vomit. Nausea is not a disease itself, but an indication that something is wrong. It is a symptom of a wide range of conditions or may be the result of an unhealthy action.

Some potential causes of nausea include:

• Gastroenteritis (stomach flu)
• Food poisoning
• Medication
• Overeating or eating too much greasy, spicy, or sugary food
• Excessive amounts of alcohol
• Concussion
• Dehydration
• Heart attack
• Reaction to strong smells
• Appendicitis
• Migraine
• Early stages of pregnancy (morning sickness)
• Motion sickness
• Ulcer

Nausea itself is usually harmless, however, it can be a symptom of a more serious issue. If your nausea is accompanied by a severe headache, severe stomach pain, difficulty breathing, a stiff neck, or confusion you should seek prompt medical attention. You should get medical help if you suspect you’ve ingested a poisonous substance or are severely dehydrated.
