Why Did I Cough Up Blood After Feeling Nauseous While Brushing My Teeth in the Morning?

Experiencing nausea and hemoptysis (coughing up blood) while brushing teeth in the morning can be alarming. This phenomenon can be caused by physiological or pathological factors. Physiological factors may result from excessive exposure to cold air at night or irritation of the throat mucosa by smoke and dust, while pathological factors may include chronic pharyngitis or bronchiectasis.

If you inhale too much cold air at night or are exposed to smoke and dust, it may irritate the throat mucosa, leading to nausea and hemoptysis when brushing teeth in the morning. Generally, no special treatment is required for this condition. Simply paying attention to staying warm in daily life and avoiding exposure to harmful substances can alleviate the symptoms spontaneously.

This is a common disease caused by bacterial or viral infections, often manifested as dry throat, sensation of a foreign body, and other symptoms. If the condition worsens, it may lead to hemoptysis. For chronic pharyngitis, compound borax solution or furacilin solution can be used for gargling under a doctor's guidance. When necessary, medications such as amoxicillin capsules or cefixime tablets can also be taken to relieve symptoms.

This condition is caused by irreversible damage to the bronchi and surrounding lung tissue, resulting in damage to the muscles and elastic tissues of the bronchial wall. It may lead to recurrent and large amounts of hemoptysis, especially in the morning. In this case, anti-infective drugs such as aztreonam for injection or ciprofloxacin hydrochloride injection should be used under a doctor's guidance, along with hemostatic drugs.

Apart from the above reasons, hemoptysis may also be related to other diseases such as sinusitis and pneumonia. If this condition persists or worsens, it is recommended to seek medical attention promptly for a detailed examination to identify the underlying cause and take corresponding treatment measures. Maintaining good living habits and environmental hygiene can also help prevent the occurrence of similar symptoms.
