What is Nausea?
Nausea is the sensation of unease and discomfort in the stomach with an urge to vomit or empty the contents of the stomach. Nausea can occur as a result of ‘morning sickness’ in pregnancy, flu, motion sickness, infection, food poisoning, overindulgence, blocked intestine, illness, concussion or brain injury, appendicitis and migraines.
Nausea doesn't always lead to vomiting (the forcible voluntary or involuntary emptying of stomach contents through the mouth) but can certainly create queasiness in the stomach, a sensation of biliousness and upset stomach. Nausea can originate from problems in the brain and it is also associated with organs of the upper gastrointestinal tract (esophagus, stomach, small intestine, liver, pancreas, and gallbladder). Nausea may also be caused by pain, certain motion, certain medications and diseases of non-gastrointestinal organs.
It is recommended that if nausea is prolonged and symptoms persist that you consult your doctor for further investigation.
