Chronic sinusitis may appear with blood in the secretion when sucking back, but blood in the secretion of sucking back may also be caused by dryness of nasal mucosa, deviated septum, nasopharyngeal carcinoma and other factors.
1. Chronic sinusitis: often evolved from acute sinusitis, when the inflammation stimulates the sinus mucosa, it can make the sinus mucosa congested and edematous, and a small amount of nasal bleeding due to nose blowing or localized mucous membrane erosion may lead to the patient’s blood in the regurgitation of snot.
2. Dryness of nasal mucosa: when the environment is dry, it may cause dehydration of nasal mucosa, which may increase the fragility of capillaries and lead to the phenomenon of blood in the snot, which may be accompanied by dry throat and other discomforts.
3. Deviated nasal septum: mostly related to uneven development of nasal cavity and trauma, etc. Deviated nasal septum may cause nasal congestion, headache, tinnitus, loss of sense of smell, etc., and may be accompanied by nosebleed or sniffing back blood.
