Nausea is that feeling you get once you think you would possibly throw up. Vomiting is once you actually throw up. These 2 symptoms can happen together. But sometimes people feel nauseous without throwing up, and a few people throw up without feeling nauseous first.

The most common causes include:

  • Food poisoning – this could happen if you eat food that has gone bad. It’s basically an infection in your stomach. Infections like these often also cause diarrhea. Different kinds of infections that affect the stomach or intestines may cause nausea and vomiting.
  • Dizziness or motion sickness – this could happen if you’re on a ship or in a car, or something else that moves. It may happen if there’s something wrong inside your ears that affects your balance.
  • Medicines – Many different medicines can cause nausea or vomiting. Some examples are antidepressants, antibiotics, vitamins, contraception pills, and pain medicines. People who are on chemotherapy for cancer treatment or who are under anaesthesia also often have nausea or vomiting. Sometimes, those who use cannabis (marijuana) over a long time have repeated episodes of vomiting.
  • Pregnancy – many ladies who are pregnant have nausea or vomiting. People sometimes call this “morning sickness,” but it can happen at any time of day.
  • Gastroesophageal reflux disease (GERD) – GERD is a condition that causes the juices that are within the stomach to leak back up into the esophagus, the tube that connects the throat to the stomach. It can sometimes cause nausea.
  • Problems with the stomach or intestines – In some people, the stomach or intestines don’t move food along the way that they are supposed to. In others, the intestines can get blocked. Both of these problems can cause nausea or vomiting.
  • Migraine headaches – Some who get migraine headaches have nausea during their headaches.
  • Alcohol – Drinking too much alcohol can cause nausea and vomiting.

Foods that are high in carbohydrates (“carbs”), like bread or saltine crackers, can help settle your stomach. Some people also find that ginger helps with nausea. you must avoid foods that have lots of fat in them. they’ll make nausea worse. Call your doctor if your symptoms come back once you attempt to eat.
    • Avoid strong smells, like the smell of perfume
