What disease is it that causes bloody nasal discharge for a month?

Snot refers to a kind of mucus in the nasal cavity. Snot is easy to appear when the body has a cold or the nasal cavity is irritated. The shape of the snot and the degree of mucus also represent the type of disease. Snot with blood may be a manifestation of nasal disease. This may be a condition caused by sinusitis, or it may be a symptom caused by external bacteria and needs to be treated in time.

What is the disease of bloody nasal discharge?

This situation may be caused by sinusitis. It is recommended to check with nasal endoscopy, preferably combined with sinus CT.

Inflammation of one or more sinuses is called sinusitis. The affected sinuses include the maxillary sinus, ethmoid sinus, frontal sinus and sphenoid sinus. This is a disease with a high incidence rate in the population and affects the quality of life of patients. Sinusitis can be divided into 2 types: acute and chronic sinusitis. Acute sinusitis is mostly caused by upper respiratory tract infection, and bacterial and viral infections may occur simultaneously. Chronic sinusitis is more common than acute sinusitis, and multiple sinuses are often affected at the same time.

Causes

Sinusitis can be divided into 2 types: acute and chronic sinusitis. The course of acute sinusitis was 12 weeks.

The disease is divided into mild and moderate/severe according to the visual analog scale (VAS) score (10 cm) of severity: mild = VAS 0-4 cm; moderate/severe = VAS 5-10 cm.

1. Acute sinusitis

Acute sinusitis is mostly caused by upper respiratory tract infection, and bacterial and viral infections may occur simultaneously. Common bacterial flora include various pyogenic cocci such as Streptococcus pneumoniae, hemolytic Streptococcus and Staphylococcus, followed by Haemophilus influenzae and Moraxella catarrhalis, the latter of which is common in children. Other pathogens include streptococci, anaerobic bacteria and Staphylococcus aureus. Those caused by dental diseases are mostly anaerobic infections, and the pus often has a foul odor. Fungi and allergies may also be causative factors.

Acute sinusitis infections often come from: sinus infection, nasal infection, adjacent tissue infection, blood infection, trauma infection, as well as systemic factors and toxic factors.

2. Chronic sinusitis

(1) The transformation from acute sinusitis to chronic sinusitis is often due to improper treatment of acute sinusitis, or failure to treat it thoroughly, resulting in repeated attacks and prolonged illness. This is the primary cause of this disease.

(2) Obstructive causes Obstructive diseases in the nasal cavity, such as nasal polyps, hypertrophic turbinate, nasal stones, deviated nasal septum, nasal tumors, nasal packing, etc., which hinder the ventilation and drainage of the nasal cavity and sinuses, are the main causes of this disease.

(3) The pathogens are highly virulent. Certain highly virulent pathogens, such as beta-hemolytic streptococci in scarlet fever, can easily turn acute sinusitis into a chronic disease.

(4) Odontogenic infection: Because the roots of the upper molars are adjacent to the floor of the maxillary sinus, if the dental disease is not cured, it can easily lead to odontogenic chronic maxillary sinusitis.

(5) Trauma and foreign bodies, such as traumatic fractures, retained foreign bodies, or blood clot infection, lead to chronic sinusitis.

(6) Sinus anatomical factors: The special or abnormal anatomical structure of each sinus is not conducive to ventilation and drainage, which is also an intrinsic factor that cannot be ignored.

(7) Systemic factors include various chronic diseases, malnutrition, and excessive fatigue that lead to low body resistance. At the same time, there are various allergic factors and causes induced by bronchiectasis.
