Specialists from the Mayo Clinic in the US have disclosed several coronavirus symptoms that precede respiratory manifestations of COVID-19.
Covid-19 might cause mild gastrointestinal symptoms, including a loss of appetite, nausea, vomiting, and diarrhea,
These symptoms might only last one day.
Some people with Covid-19 have diarrhea and nausea before developing fever and respiratory symptoms.
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. But in the case of coronavirus infection, nausea is followed by cough, fever, loss of taste, and smell.
