Nausea and dry heaving during tooth brushing or face washing

      In general, nausea and dry heaving during toothbrushing may be caused by non-disease factors such as improper brushing techniques, or by disease-related factors such as chronic pharyngitis or chronic tonsillitis. The specific analysis is as follows:

  I. Non-disease Factors

       Brushing too deeply into the throat area can cause discomfort in the pharynx. Especially in individuals with naturally sensitive gag reflexes, this may easily trigger symptoms of nausea and dry heaving. Therefore, it's recommended to adjust brushing techniques appropriately to reduce irritation to the throat and alleviate morning episodes of nausea and dry heaving during toothbrushing.

  II. Disease-related Factors

    1. Chronic Pharyngitis

       Chronic pharyngitis refers to diffuse chronic inflammation of the pharyngeal mucosa, submucosal tissues, and lymphoid tissues. Patients often experience a foreign body sensation, itching, burning, dryness, or mild pain in the throat. Additionally, their gag reflex tends to be more sensitive, making them more reactive to external stimuli. As a result, toothbrushing in the morning may easily irritate the throat, leading to nausea and dry heaving. Patients may take medications such as pharyngitis tablets, omeprazole, or rabeprazole under medical guidance. If necessary, patients are advised to seek timely treatment at a reputable hospital to properly manage chronic pharyngitis.

    2. Chronic Tonsillitis

       The exact pathogenesis of chronic tonsillitis remains unclear, but it may result from poor drainage in the tonsillar crypts, leading to infection by bacteria, viruses, or other pathogens. During toothbrushing, stimulation of the tonsils may trigger nausea and dry heaving. Treatment should be conducted under a doctor’s supervision using antibiotics such as amoxicillin, tetracycline, or gentamicin. Patients are advised to undergo thorough medical evaluation at a hospital to prevent worsening of symptoms.

      Besides the above-mentioned causes, nausea and dry heaving during oral hygiene routines may also stem from other conditions such as reflux laryngitis, gastrointestinal disorders, or gastroesophageal reflux disease (GERD). It is recommended to promptly visit a hospital for proper diagnosis and treatment to avoid delays that could lead to disease progression.
