Share the article


Have you ever had this queasy feeling in the stomach, mostly while travelling or watching/reading something during travel? Or after having eaten that doesn’t agree with your body? The term that refers to all these is called “nausea”. A word for the queasy sensation in your stomach indicates you could vomit.

An uneasy feeling in the stomach called nausea frequently precedes vomiting. Vomiting forces stomach contents up through the mouth, voluntarily or involuntarily.

Why does Nausea occur?

Numerous factors can trigger Nausea. For example, some people have increased sensitivity to sounds, smells, tastes, medicines, and the impacts of certain medical disorders. These items can all make you feel queasy. Below are some of the most typical causes of Nausea.

Gastroesophageal reflux disease or heartburn (GERD)

When you eat, the food in your stomach may reflux back up into your oesophagus due to heartburn or gastroesophageal reflux disease (GERD). This produces a burning sensation that makes people feel sick.

Infection or virus

Viral or bacterial gastrointestinal problems can cause Nausea. Food poisoning is a condition brought on by foodborne germs. Additionally, viral infections might make you sick.

Seasickness and motion sickness

A bumpy trip in a car can cause motion sickness and seasickness. In addition, this movement may misalign the signals from the senses to the brain, which might produce Nausea, vertigo, or vomiting.


Foods that are hot or heavy in fat or when consumed in excess can upset the stomach and make you feel sick. Eating foods to which you are allergic might make you sick as well.


Symptoms of Nausea might be exacerbated by severe pain. This applies to severe illnesses, including pancreatitis, gallstones, and/or kidney stones.


The lining of the small intestine or the stomach may develop sores, or ulcers, which can cause Nausea. An ulcer might make you feel burning and nauseous just after eating.

Additionally, Nausea can be a sign of several different medical disorders, such as:

  • Benign paroxysmal positional vertigo (BPPV) (BPPV)
  • Hearing loss
  • Chest pain
  • Intestinal blockage
  • Liver disease or liver failure
  • Meningitis
  • Migraine

Symptoms and Signs of Nausea

You generally feel ill to your stomach when you have Nausea.

  • Weakness
  • Sweating
  • Saliva accumulating in your mouth
  • Urge to vomit

What Causes Off Nausea or Vomiting?

Vomiting and Nausea are symptoms of many different disorders, including:

  • Seasickness or motion sickness
  • Early stages of pregnancy (between 25% and 55% of pregnancies have vomiting, while between 50% and 90% experience nausea)
  • Vomiting caused by medication
  • Emotional stress (such as fear)
  • A gallbladder condition
  • Food poisoning
  • Infections (such as the “stomach flu”)
  • Overeating

  • Bulimia or other psychological conditions
  • Slow stomach emptying, often known as gastroparesis (a condition that can be seen in people with diabetes)
  • Intestine blockage
  • Appendicitis

How Is Vomiting Diagnosed?

Your doctor will assess your medical history, inquire about your symptoms, and perform a physical exam to ascertain what is causing your Nausea. In addition, they may do specific tests, such as blood, urine, and sometimes a pregnancy test, and search for indications of dehydration.

The prognosis for Nausea

Most of the time, Nausea is not dangerous and subsides within a day or two.

But Nausea can also signify a wide range of other diseases. Rarely, it may be a symptom of a serious or life-threatening medical condition.

Duration of Nausea

The reason will determine how long Nausea lasts.

Vomiting and Nausea brought on by stomach flu typically start to improve within a day. However, food poisoning-related nausea and vomiting can last up to 48 hours. If your Nausea persists for more than a week, call your doctor; you might also want to check to see if you could be pregnant. Likewise, contact your doctor if vomiting persists along with your Nausea for more than a day.

Treatment and medical options for Nausea

Self-care techniques that are low risk can frequently relieve Nausea. The following advice might be helpful:

  • Sit down and relax. Too much activity might worsen Nausea.
  • Stay hydrated. Try to drink short sips of cool, clear, carbonated, or sour liquids like water, ginger ale, lemonade, or soda. Additionally, mint tea may reduce Nausea. Dehydration may be avoided using oral rehydration products like Pedialyte.
  • Avoid smells with a strong scent. Smoke, perfume, and the scent of food can trigger.
  • Avoid more triggers. Other factors that might cause Nausea and vomiting include hot weather, humidity, flickering lights, and driving.
  • Eat bland meals. If you’ve been throwing up, wait until your body feels ready to ingest solid foods. Start with simple-to-digest items like rice, crackers, toast, applesauce, and bananas when you feel you can handle solids. If you have been vomiting or feel like you might start, try cereal, rice, fruit, and salty or high-protein, high-carbohydrate items when you can hold them down without throwing up.
  • Do not eat anything hot or greasy. These meals may worsen your Nausea.


  • Safe home remedies, advice, and techniques for preventing Nausea include the following.
  • Take frequent, smaller meals throughout the day rather than three large ones.
  • Eat slowly
  • Avoid eating things that are hard to digest.
  • Eat cold or room-temperature food.
  • After eating, nap and keep your head approximately 12 inches above your feet.
  • If you wake up feeling queasy, eat a few crackers before getting out of bed or have a high-protein snack before going to bed (lean meat or cheese).
  • Avoid consuming too much fluids during meals.
  • To avoid dehydrating, consume six to eight 8-ounce glasses of water daily.
  • Wait until you feel less queasy before eating.
