Nausea and Vomiting
Nausea and vomiting are common symptoms that can be the result of a variety of conditions, including lung infections. While nausea and vomiting might not be the only sign that a person has a lung infection, they are some of the most common symptoms associated with respiratory diseases in general.
Just because a person is nauseous doesn’t mean it’s from the lungs; however, if this is combined with other symptoms like fever, cough, or shortness of breath, it might be worth seeing a doctor about the signs.
