My sister complains of her nose and breath smelling constantly, what could this be from? The foul smells in her nose bug her more than anything
Sinusitis. Sounds like sinusitis to me. How long has she had these symptoms? Does she have history of nose allergy? Any condition that blocks off the sinus drainage channels, including colds, allergies, non-allergic rhinitis, deviated nasal septum and nasal polyps, can cause sinusitis. You typically get thick, yellow, foul-smelling discharge, nasal obstruction and pressure around eyes, nose and forehead.
Nose/breath smell. How old is your sister? Foul smells in the nose of children are sometimes associated with a foreign body (bean/peanut/toy) in the nasal passage. Sinus conditions/infections can also be associated with foul nasal discharge & bad breath. Have her see her fp or an ENT doc to check for these possibilities. Tooth decay with dental abscess should also be considered.
Usually the sinuses. Bad smells sensed in the nose are usually from a sinus infection. A doctor can look inside the nose to see what is up there, and then prescribe antibiotics as needed.
