Nausea is the feeling that you might vomit (be sick). It is not a disease itself but a symptom of many different conditions. It can happen with or without vomiting.
Key facts
Yes, nausea is one of the most common symptoms people experience. Most people have it at some point in their lives.
Anyone can get nausea. It is more common in people with certain conditions like migraine, pregnancy, or digestive issues. It can affect all ages, from babies to older adults.
A doctor will ask about your symptoms, medical history, and any recent activities (like travel, food, or medicines). They may examine your stomach and check for signs of dehydration.
The doctor will try to find the underlying cause. They may ask you to keep a diary of your nausea and any triggers. You may be referred to a specialist (like a gastroenterologist) if the cause is not clear.
Treatment depends on the cause. For most nausea, simple self-care helps. If there is an underlying condition, that will be treated. Medicines to stop nausea (antiemetics) may be prescribed if needed.
If you have chronic nausea (lasting weeks or more), try to identify and avoid your triggers. Keep a diary of what you eat and do before nausea starts. Eat smaller meals more often. Keep plain crackers or water nearby.
Avoid heavy meals, fried foods, and very sweet foods. Eat small, frequent meals. Light exercise like walking can help digestion, but do not exercise if you feel very nauseous.
Constant nausea can be frustrating and tiring, and may lead to anxiety or depression. It is important to talk to your doctor about how you feel, not just the physical symptoms. Mental health support can help you cope.
Not all nausea can be prevented, but you can reduce your risk. Avoid known triggers, practice good hygiene to prevent stomach bugs, and take motion sickness medication before travel if you are prone to it.
There is no vaccine specifically for nausea, but vaccines for stomach infections (like rotavirus) can reduce a common cause in children.
There is no routine screening for nausea. If you have a condition that commonly causes nausea (like migraine), follow your doctor’s management plan.
For most people, nausea goes away once the cause is treated. With proper care, even chronic nausea can be managed well. Talk to your healthcare provider for a plan that works for you.

If symptoms are severe, worsening, or urgent, call your local emergency number or seek emergency care.
If nausea is severe or persistent, a doctor may recommend medications that help prevent vomiting. These are called antiemetics. They come as tablets, dissolving wafers, injections, or suppositories. Always follow your doctor’s advice on the right treatment for you.
Surgery is very rarely needed for nausea alone. It may be needed if the nausea is caused by a condition like a bowel obstruction or appendicitis, but those cases are handled separately.
