What is nausea?

Nausea is the feeling you get when you’re about to be sick (as in vomit). Sometimes it leads to vomiting, but not always. The best way to describe it is as an uncomfortable feeling in your throat and stomach, where you feel an urge to vomit.

It can be caused by a range of things, like migraines, food poisoning, viruses, being pregnant, and some people get it when they travel by boat, car or air (travel or motion sickness). Nausea can also be a side effect of treatment like chemotherapy.

Who gets nausea?

Anyone can get nausea, and most people will get it at least once. Sometimes we know the cause and other times it can happen unexpectedly.

If you have migraines with ‘aura’, nausea can be a symptom. You might get nausea during the first few weeks of being pregnant (this is called morning sickness). Nausea can also happen if you get ‘travel sick’ when in a moving car or boat (this is also called motion sickness).

How common is nausea?

It’s common to get it occasionally, particularly in situations that can trigger it; for example being on a moving boat, or having a virus or a stomach bug. Because it can be caused by so many different things, and can often be transient, it’s not really possible to estimate how often it happens. (A lot of the time people will get it, it will pass, and they won’t need to tell a doctor about it.)

It’s very common to get morning sickness (which causes nausea and vomiting) during the early stages of pregnancy. Estimates of how common it is vary, from 50%^[1] to 70%. ^[2]

Nausea is more common in people taking certain treatments or with specific medical conditions. For example, if you’re having chemotherapy then you’re more likely to have nausea as a side effect. Some medicines for pain relief like ibuprofen and paracetamol can also cause nausea.

How we source info.

When we present you with stats, data, opinion or a consensus, we’ll tell you where this came from. And we’ll only present data as clinically reliable if it’s come from a reputable source, such as a state or government-funded health body, a peer-reviewed medical journal, or a recognised analytics or data body. Read more in our editorial policy.

What medications are there for nausea?

There are a lot of different types of anti-nausea medication, including antihistamines and anticholinergic agents. They work in a broadly similar way to treat nausea, but contain different ingredients. Nausea treatment usually works by interrupting the passage of nausea signals, or your brain’s interpretations of them. These drugs usually work on receptors in the vomiting sector of the brain, making them less sensitive to chemical messages. This helps to stop the chemical transmission which causes the uncomfortable feeling, relieving symptoms of nausea. There are other treatments for nausea that work in the gut to help food move through it faster. If you use these, you’ll normally only take them short term, and they’re better for nausea being caused by digestive issues or migraine.

Is there a ‘best’ treatment for nausea?

Not as such. There are a few different treatments available for nausea. The type that will work best depends on a number of factors, like how severe your nausea is and what’s causing it. Dopamine blocking treatments can help to treat nausea caused by medication, morning sickness or vertigo. Antihistamines can be helpful for nausea caused by travel sickness. Anticholinergics are useful for nausea caused by problems in the gut. If you’re not sure which treatment is best for you, we can help you find the right option.

Does nausea always need treatment?

Not always. Avoiding triggers can help to reduce nausea. For example, if you know you suffer from motion sickness, then it can help not to read while in a moving car. If you get nausea associated with migraine, taking steps to limit the risk of migraine can help. It depends on what your migraine triggers are, but this might be making sure you get enough sleep, or avoiding specific foods that you know cause them. But nausea treatment can help if your symptoms are brought on by something unavoidable, like travelling, morning sickness or a certain type of medication. You should get medical advice if you continually get nausea with no obvious cause.

FAQ: Nausea

Have something specific you want to know? Search our info below, or ask our experts a question if you can’t find what you’re looking for.

How long does nausea last for?

Answer:

It can depend pretty heavily on what’s causing it. For mild cases, it might subside within a few hours. But for more severe cases, like when it’s caused by food poisoning or certain medical conditions, it could last for several days. If your nausea persists or worsens, let your doctor know.

Can I prevent nausea from happening?

Answer:

While you can’t always prevent nausea, there are steps you can take to reduce your risk:

Avoid triggers: Sounds simple, but if you know certain foods or situations trigger your nausea, try to minimise your exposure to them.

Eat small, frequent meals: This can help prevent indigestion and other stomach-related issues.

Stay hydrated: Dehydration can exacerbate nausea. Drink plenty of fluids, especially water.

Manage stress: Stress can contribute to nausea, practice relaxation techniques like meditation or deep breathing.

Get enough sleep: Good sleep can help regulate your body’s functions, including digestion.

What natural remedies can help with nausea?

Answer:

While natural remedies might work for some people, you should speak to a doctor before trying any of them, especially if you’re pregnant or have underlying health problems. Some common natural remedies include:

Ginger: Ginger has shown to be effective in reducing nausea, especially for motion sickness.^[1]

Peppermint: Peppermint can soothe an upset stomach and reduce nausea.^[2]

Acupuncture: There’s a little evidence to show that acupuncture can be helpful for managing nausea, particularly postoperative nausea and vomiting.^[3]

Are there different types of nausea?

Answer:

The feeling of nausea itself is quite distinct, but there are different causes. For example, food poisoning tends to lead to both nausea and vomiting. This type of nausea can come on suddenly and be quite severe.

Nausea you get with a migraine might not lead to vomiting, but persist for a while. Travel sickness can cause nausea but this might come on more slowly, and not result in vomiting.

Can you get side effects from nausea treatment?

Answer:

Nausea treatment can cause side effects. Drowsiness is a common side effect that you can get with several different types. Others might cause headaches, constipation or insomnia. Most of the time, side effects pass fairly quickly and aren’t harmful. But if you do get side effects when using nausea treatment, it’s important to let the person who prescribed medication for you know.

If you’re concerned about side effects or have had them before when using nausea treatment, we can help you find a solution that works for you.

I did not know that increasing the dose also increased the price. Too bad.
