What is the relationship between nasal diseases and systemic diseases?

In fact, the nose is not only closely related to neighboring organs, but also related to the whole body organ system. Because the human body itself is an organic unity, nasal diseases and systemic diseases often interact with each other. The specific manifestations are: (1) the relationship between allergic diseases and nasal diseases: allergic rhinitis is also called allergic rhinitis. Clinically, although they show symptoms of local nasal mucosa allergy, such as nasal itching, sneezing, nasal congestion and so on. These patients often have allergies. (2) Relationship between cardiovascular diseases and nasal diseases: When patients suffer from arteriosclerosis or hypertension, the arterioles of nasal septum mucosa are easy to rupture and bleed; Some patients with altitude sickness, due to long-term hypoxia, have increased red blood cells and thick blood, which is prone to increase arterial pressure and increase the fragility of blood vessel walls, which is easy to cause nosebleeds. Sometimes severe nasal trauma and massive bleeding can also cause shock and persistent damage to various organs of the whole body. (3) Relationship between blood diseases and nasal diseases: Various blood diseases affect blood coagulation function due to changes in blood components, which can cause nosebleeds while causing systemic organ diseases; If nasal diseases require surgery, the existence of blood diseases increases the difficulty and danger of surgery. (4) The relationship between connective tissue disease and nasal diseases: Connective tissue disease, also known as collagen disease, is characterized by multiple organ involvement and extensive connective tissue and vascular inflammation.

Will show up in the nose. Some scholars believe that the basic pathological changes of these lesions are mainly connective tissue myxedema and fibrinoid degeneration. (5) Others: Sometimes endocrine abnormalities or changes can also affect the function of the nose, such as hypothyroidism, pregnancy and menstruation, which can cause nasal congestion in nasal mucosal swelling; When hepatic coma and uremia occur in liver and kidney diseases, the function of nasal cilia can be damaged; Some special infections, such as induration and tuberculosis, can cause harm to the nose; Although syphilis and AIDS are sexually transmitted diseases, they also have nasal symptoms.
