Hello, As per your complain spitting of blood with no other symptoms can be due to causes that can commonly cause such symptoms can be: • Gingivitis (inflammation of the gums) • Mouth ulcers • Esophagitis (inflammation of the esophagus/food pipe) • Gastritis (inflammation of the stomach lining) • Peptic ulcers, etc. But in case if there is no other associated problem it can be due to gum inflammation. In case if there are repeated episodes of the same problem consult an oral physician and get evaluated first to check your teeth, gums, and oral cavity. If no infection is ruled out then you need to consult a general physician and get a thorough examination done. Treatment can be only done once cause is ruled out. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Honey Arora
