Vasculitis is a condition characterized by inflammation of the blood vessels, which can affect blood flow to various organs. This inflammation may lead to a range of health issues, depending on which vessels are involved. Understanding the implications of vasculitis can aid in monitoring and management.

  • What exactly is vasculitis and how does it affect my body?
    MedlinePlusMay 2026

    Vasculitis is when your immune system mistakenly attacks your blood vessels, causing them to become inflamed and swollen. This inflammation can narrow or block blood vessels, making it harder for blood to flow through your body to your organs.

  • Why does my immune system attack my blood vessels?
    MedlinePlusMay 2026

    Sometimes the body's immune system gets confused and attacks blood vessels by mistake, but doctors often don't know exactly why this happens. It can be triggered by an infection, a medicine you're taking, or another disease.

  • How can I tell if the inflammation in my blood vessels is getting worse?
    MedlinePlusMay 2026

    Watch for worsening fever, increased swelling, feeling more tired or sick, or new pain or numbness in your arms or legs. Contact your doctor right away if you notice these changes getting worse.

  • Will vasculitis only affect certain parts of my body or could it spread?
    MedlinePlusMay 2026

    Vasculitis can affect blood vessels anywhere in your body—arteries, veins, or tiny capillaries—so it's not limited to one area. The inflammation can spread to different parts of your body depending on which vessels are affected.

  • What are some common triggers that might cause this condition?

    Common triggers include infections, certain medicines, or other diseases, though the cause is often unknown. Your doctor can help figure out what might have triggered your vasculitis.
