What causes vasculitis?

Many people know about vasculitis, which is a vascular disease that is very stubborn and difficult to treat. Any disease has a cause, and so does vasculitis. Vasculitis is related to many factors, and malnutrition and other factors may lead to vasculitis.

1. Smoking

The cause of vasculitis is closely related to smoking. Clinical studies have shown that most patients with vasculitis have a history of smoking to varying degrees. Tobacco contains nicotine, which can cause spasms of small blood vessels, resulting in vascular damage and increasing the incidence of vasculitis. In addition, smoking can excite the sympathetic nerves, increase the levels of vasoactive substances such as adrenaline, norepinephrine and 5-hydroxytryptamine, cause vasospasm and damage endothelial cells, and increase the incidence of vasculitis.

2. Malnutrition

The occurrence of vasculitis is related to various malnutrition, especially the deficiency of vitamin B and vitamin C, which can easily cause various vascular diseases, including vasculitis.

3. Bacterial infection

The cause of vasculitis is related to bacterial infection. For example, paronychia, traumatic infection, tinea pedis, etc. are closely related to the occurrence of vasculitis. This is because the infection factors reduce the resistance of local blood vessels, thus leading to the occurrence of vasculitis.

4. Cold Environment

The occurrence of vasculitis is also related to the environment, especially the cold environment, which can cause the human body's blood vessels to constrict, thereby increasing the occurrence of vasculitis.
