What is nausea in the morning?

The feeling of nausea and vomiting after getting up in the morning is mostly caused by pharyngitis, pharyngitis will make the mucous membrane of the throat congested and edematous, and the throat mucosa will be stimulated to produce secretions. After a night's rest, the secretions of the throat will accumulate more, so the symptoms of nausea and vomiting will occur in the morning. If the patient has acid reflux symptoms at the same time, it may also be caused by reflux esophagitis.
