Nausea is a feeling of queasiness or an upset stomach that often precedes vomiting. It can be caused by various factors, including motion sickness, food poisoning, and certain medications. When nausea persists without vomiting, it can be extremely uncomfortable and debilitating.
- Feeling queasy or sick
- Upset stomach
- Loss of appetite
- Dizziness and lightheadedness
- Cold sweats
- Increased salivation
- Pale complexion
- Motion sickness: Caused by repeated movement, such as in a car, boat, or airplane.

- Underlying medical conditions: Nausea can be a symptom of conditions such as gastrointestinal disorders, liver disease, and pregnancy.

In some cases, despite feeling nauseous, you may be unable to vomit. This can be due to:
- Empty stomach: If your stomach is empty, there is nothing to vomit.
- Blockage in the digestive tract: A blockage, such as a tumor or scar tissue, can prevent vomit from passing through.
- Medication: Certain medications, such as antiemetics, can suppress the urge to vomit.
- Underlying medical conditions: Conditions that affect the nervous system, such as migraines or strokes, can interfere with the vomiting reflex.
- Hydrate: Drink plenty of fluids, such as water or clear broths, to prevent dehydration.
- Eat bland foods: Focus on eating easily digestible foods, such as crackers, rice, or plain yogurt.
- Ginger: Consuming ginger in tea, candy, or supplements can help alleviate nausea.
- Acupressure: Applying pressure to specific points on the body, such as the P6 acupressure point on the wrist, can help reduce nausea.
- Over-the-counter medications: Anti-nausea medications, such as meclizine or bismuth subsalicylate, can help suppress nausea.
- If nausea is severe or persistent.
- If vomiting lasts for more than 24 hours.
- If you have a fever or other symptoms of dehydration.
- If you are unable to keep down any liquids.
