A Normal Calcium Level
June 30, 2026
A Normal Calcium Level For most adults, a normal total blood calcium level (measured via a standard blood test called a serum calcium test) is typically between 2.2 and 2.6 millimoles per litre (mmol/...
Vasculitis is a rare but serious group of autoimmune conditions characterised by inflammation of the blood vessels. When your blood vessels become inflamed, they can thicken, narrow, or scar, which restricts vital blood flow to your organs and tissues.
If you are experiencing unexplained fatigue, skin rashes, or joint pain, understanding the early warning signs is critical.
This guide breaks down the symptoms, causes, and treatment options to help you navigate a diagnosis.
Symptoms of vasculitis vary depending on which organs are affected. However, many patients experience a combination of these ten common “red flags”:
Unexplained Fever: Persistent low-grade fevers that aren’t linked to a cold or flu.
Profound Fatigue: A level of exhaustion that doesn’t improve with rest.
Purpura (Skin Rash): Distinctive purple or red spots, often appearing on the lower legs.
Joint Pain: Aching or swelling in the joints, similar to arthritis.
Numbness or Tingling: Often felt in the hands or feet (peripheral neuropathy).
Unintended Weight Loss: Dropping weight quickly without changes to diet or exercise.
Shortness of Breath: This can indicate inflammation in the lungs or heart.
Persistent Headaches: Especially when accompanied by scalp tenderness (common in Giant Cell Arteritis).
Night Sweats: Waking up drenched, often paired with systemic inflammation.
Vision Changes: Blurred or double vision, which requires immediate medical attention.
While the exact trigger is often unknown, vasculitis occurs when the immune system mistakenly attacks healthy blood vessels. Common risk factors and triggers include:
Infections: Such as Hepatitis B or C.
Autoimmune Disorders: Conditions like Lupus (SLE) or Rheumatoid Arthritis.
Medication Reactions: Certain drugs (e.g. methyldopa, hydralazine) can trigger a flare.
Genetics: Specific genetic markers may make you more susceptible to vessel inflammation.
Types of Vasculitis by Vessel Size
Doctors categorise the disease based on the size of the affected vessels:
Large Vessel: Giant Cell Arteritis (GCA) or Takayasu arteritis.
Medium Vessel: Polyarteritis nodosa or Kawasaki disease.
Small Vessel: ANCA-associated vasculitis or Henoch-Schönlein purpura (HSP).
Early intervention is the “gold standard” for preventing permanent organ damage. You should schedule an appointment with a GP or specialist if:
You have a persistent, unexplained rash or “spots” under the skin.
You experience sudden vision loss or severe, new headaches.
You notice signs of kidney distress, such as blood in the urine.
You feel a “foot drop” or sudden weakness in a limb.
Note: If you experience sudden chest pain or difficulty breathing, seek emergency medical services immediately.
Diagnosing vasculitis is a bit like detective work. It typically involves a multidisciplinary team including Rheumatologists, Nephrologists, and Dermatologists.
Diagnostic Tools
Blood Tests: To check for inflammatory markers like CRP or specialised ANCA antibodies.
Imaging: CT, MRI, or Chest X-rays to visualize vessel narrowing.
Biopsy: Removing a small tissue sample to confirm inflammation under a microscope.
Treatment Options
The primary goal is to achieve remission (stopping the active inflammation).
Corticosteroids: (e.g. Prednisolone) for rapid inflammation control.
Immunosuppressants: To “calm” the immune system long-term.
Biological agents: Targeted therapies for more complex or severe cases.
While a diagnosis can feel overwhelming, modern treatments allow most patients to lead full lives. Regular monitoring is essential to prevent relapses and manage potential side effects of medication.
