What is nausea?

Nausea is stomach discomfort and the sensation of wanting to vomit. Nausea can be a precursor to vomiting the contents of the stomach. The condition has many causes and can often be prevented.

Nausea and vomiting are not diseases, but symptoms of many different conditions, such as infection (“stomach flu”), food poisoning, motion sickness, overeating, intestinal disease, concussion or brain injury, appendicitis, and migraines.

What is the difference between nausea and vomiting?

It is an upset stomach that is often accompanied by a desire to vomit but does not always lead to vomiting. Vomiting is the forced or involuntary emptying of stomach contents through the mouth (“vomiting”). Some of the triggers for vomiting are the stomach and intestines (infection, injury, and irritation from food), inner ear (dizziness and motion sickness), and brain (head injury, brain infections, tumours, and migraines).

Who is most likely to experience nausea and vomiting?

These occur in children and adults. People who undergo cancer treatments, such as radiation therapy or chemotherapy, have an increased risk of vomiting. Pregnant women may also experience vomiting during the first trimester, which is commonly known as “morning sickness.” It is estimated that 50 to 90 per cent of pregnant women experience nausea, while 25 to 55 per cent experience vomiting.

Symptoms of vomiting

It is difficult to explain to most people. It can be very uncomfortable, but not painful, and can be felt in the back of the throat, chest, or abdomen. The feeling is associated with an aversion to food or the desire to vomit. When the body is ready to vomit, the following sequence can occur:

  • Relaxation of the muscular network between the esophagus and the stomach.
  • The abdominal muscles and the diaphragm contract.
  • Close the trachea (larynx).

When a person vomits, the contents of the stomach are expelled through the esophagus and mouth.

As a result of these bodily actions, you may experience recoil when you feel nauseous. Recovering the rhythmic contractions of the respiratory and abdominal muscles that occur without your control. Excessive sweating sometimes causes nausea.
