What causes early morning bloody spit?

Early morning bloody spit can be caused by several factors, including irritation or injury to the throat, such as from excessive coughing or dry air. Conditions like bronchitis, sinus infections, or even gum disease can also lead to blood in sputum. In some cases, it may indicate more serious issues like pneumonia or lung cancer, so it’s important to consult a healthcare professional for a proper diagnosis if this symptom occurs.
