What causes nausea normally?
Nausea is a non-specific symptom because the sensation has many possible causes.
Gastrointestinal infections and food poisoning are the two most common causes of acute nausea.
This type of nausea is often accompanied by diarrhoea and vomiting.
If your nausea comes with a headache and a high temperature, it is more likely that you have an infection such as the flu.
If you have a headache and are sensitive to light and sound at the same time as feeling sick, you could have a migraine.
Nausea that comes with heartburn or bloating after eating could be down to acid reflux.
If you feel dizzy and nauseous, you could have labyrinthitis or vertigo.
Sometimes nausea is a side effect from a medication you are taking such as chemotherapy, or it could be a sign of morning sickness in early pregnancy.
Other common causes of nausea are gastroenteritis and other gastrointestinal disorders, motion sickness, fainting, low blood sugar and lack of sleep.
Sometimes nausea is caused by disgust and depression.

Is nausea a symptom of Covid?
Nausea isn’t one of the most common symptoms of Covid, but it has been seen in plenty of cases.
According to the Mayo Clinic: “Covid-19 might cause mild gastrointestinal symptoms, including a loss of appetite, nausea, vomiting and diarrhoea.
“These symptoms might only last one day.
“Some people with Covid-19 have diarrhoea and nausea prior to developing fever and respiratory symptoms.”
A study from Stanford Medicine looked at the medical records of 116 people who had tested positive for Covid-19.
Nearly a third had digestive symptoms such as nausea, loss of appetite, vomiting or diarrhoea.
You should only get a Covid test if you have a high temperature, a new, continuous cough or you’ve lost your sense of smell or taste or it’s changed.
You should also get a test if you’ve been asked to get a test by a local council, you’re taking part in a government pilot project, or you’ve been asked to get a test to confirm a positive result.
If none of the above applies but you feel nauseous, you shouldn’t get a test for free.
You could pay for a private test for peace of mind, but it is very unlikely that you have coronavirus if your only symptom is nausea.
The most common symptoms are fever, dry cough, and tiredness.
Other symptoms include aches and pains, sore throat, diarrhoea, conjunctivitis, headache, loss of taste or smell, a rash on the skin, or discolouration of fingers or toes.
Serious symptoms are difficulty breathing or shortness of breath, chest pain or pressure, and loss of speech or movement.
If you aren’t experiencing other coronavirus symptoms, you should look at other causes of nausea instead of suspecting coronavirus.
