What Is Vasculitis?
Vasculitis is a condition where the blood vessels become inflamed. The inflammation causes the blood vessels to become enlarged and results in the restriction of blood flow. The restriction of blood flow may result in damage to the organs that are affected.
There are many types of vasculitis. It may affect a single organ, or may also target multiple parts of the body. The condition can be short-term or long-term.
Doctors classify vasculitis into three types. These are based on the sizes of the affected blood vessels:
- Large vasculitis. Takayasu’s arteritis and temporal arteritis would fall under this type.
- Medium vasculitis. An example of this is Buerger’s disease.
- Small vasculitis. Behcet’s syndrome and cutaneous vasculitis fall under this type.
What Are the Causes of Vasculitis?
The exact mechanisms that occur in these diseases are unknown.
There is a possibility that it might be some form of allergic reaction, or may be brought about by certain types of medication. It is also possible that an infection triggers an abnormal response from the immune system, which leads to blood vessels getting damaged.
The condition may also be connected to diseases of the immune system like lupus or rheumatoid arthritis.
General symptoms include:
- Feeling of tiredness
- Weight loss
Other symptoms will depend on which part of the body is affected:
