Mouth | General Practice | Blood in Saliva or Spit-up (Symptom)
Blood in Saliva or Spit-up: Description
The presence of blood in the saliva does not involve every time a bleeding from the mouth, known by the medical term of stomatorrhagia. The mouth communicates with the nose, esophagus and larynx via the throat. This implies that bloody saliva may also occur due to bleeding in the nasal cavity, respiratory or gastrointestinal tracts.
Blood in Saliva or Spit-up: Causes
Tracing the cause may be easier if the blood in the saliva is only evident or more pronounced in one of these situations: after or during vomiting, regurgitating or when belching indicates bleeding from the esophagus; after or during coughing (hemoptysis) or sneezing indicates bleeding from the airways or lungs; after sneezing, blowing the nose, in post nasal drip, with nasal congestion or accompanying a bleed from the nose indicates bleeding from the nasal cavity. If there is blood in the saliva without any clear correlation with the features mentioned above, then pathology within the mouth has to first be excluded before the neighboring cavities are investigated.
