Do you vomit phlegm when you have pneumonia?

Yes, vomiting phlegm can occur in individuals with pneumonia, especially if they are coughing excessively or experiencing nausea. Pneumonia often leads to the production of mucus in the lungs, which may be coughed up and could potentially be vomited if it irritates the stomach. However, it's more common to expect coughing up phlegm rather than vomiting it. If someone experiences this, they should consult a healthcare professional for proper evaluation and treatment.
