Takayasu arteritis awareness

Overview

Takayasu arteritis (TAK) is a rare condition in which the body's own immune system attacks the walls of the large arteries — the blood vessels that carry blood from your heart to the rest of your body. This causes inflammation (swelling) that can narrow, block, or weaken the arteries. Over time, blood flow may be reduced, leading to symptoms like tiredness, pain, or high blood pressure.

No, Takayasu arteritis is rare. It affects roughly 1–3 people per million each year, though it may be underdiagnosed.

It most commonly affects young women, usually between the ages of 15 and 40. However, it can also occur in men, children, and older adults.

Symptoms

Common symptoms

• Unusual tiredness or feeling overwhelmingly fatigued
• Unexplained low-grade fever or night sweats
• Muscle and joint pains
• High blood pressure (which can be found during a routine check)
• Dizziness or lightheadedness
• Headaches
• Pain or tingling in the arms or legs, especially with movement
• Weak or absent pulse in the arms or legs (difficult to feel)
• Vision changes or blurry vision
• Chest pain or abdominal pain

Symptoms in children

• Unexplained fever
• Weight loss or poor growth
• Headaches
• High blood pressure
• Unusual tiredness or weakness

Symptoms in older adults

• Symptoms similar to younger adults, but may begin more gradually
• Confusion with other age-related conditions like arthritis or heart disease
• More damage to arteries may be present when the condition is found

Causes

Main causes

• The exact cause is not yet known, but it is believed to be an autoimmune disease, meaning the immune system mistakenly attacks the walls of the large arteries.
• A combination of genetic factors and an environmental trigger, such as an infection, may start the process in some people.

Risk factors

• Being female
• Being between age 15 and 40
• Having an Asian, Middle Eastern, or Latin American background
• Having a family history of autoimmune disease in rare cases

When to see a doctor

See a doctor urgently if:

• If you have sudden chest pain, vision loss, stroke-like symptoms, severe shortness of breath, or fainting, call your local emergency number right away.
• If you notice a new weak pulse, pain, coolness, or loss of function in an arm or leg, seek same-day medical attention.

Book a routine appointment if:

• See your doctor if you have persistent and unexplained fatigue, fever, weight loss, headaches, or high blood pressure.
• If you have symptoms that worry you or that don't improve, make an appointment to talk about them.

Diagnosis

There is no single test to confirm Takayasu arteritis. Your doctor will take a detailed medical history, do a physical exam, and use a combination of blood tests and imaging scans to look inside your arteries.

Tests that may be done

• Blood tests to look for signs of inflammation (such as ESR and CRP) and to rule out other conditions
• MRI (magnetic resonance imaging) or MR angiography to see the aorta and its branches
• CT (computed tomography) angiography for detailed images of blood vessels
• Ultrasound to check blood flow in the arms, neck, or abdomen
• Sometimes a biopsy (a small sample of tissue) is not needed, but may be considered in unusual cases

What to expect at your appointment

You will likely be referred to a specialist such as a rheumatologist or a vascular specialist. Diagnosis can take time because symptoms overlap with other conditions. Your team will explain each test and help you understand the results.

Treatment

Treatment for Takayasu arteritis focuses on reducing inflammation in the arteries, protecting blood vessels from damage, and managing symptoms such as high blood pressure. With good care, many people can live active lives.

Self-care at home

• Take your medicines exactly as prescribed, even if you feel well.
• Monitor your blood pressure at home if your doctor advises it.
• Keep track of your symptoms in a diary to share with your care team.
• Get enough rest and pace your activities.
• Stop smoking and avoid secondhand smoke — smoking especially harms blood vessels.

Medical treatments

Treatment involves medications that calm the immune system and reduce inflammation, such as glucocorticoids (anti-inflammatory steroids). When the condition is active, doctors may also use medications to lower blood pressure or prevent blood clots. These medicines need close monitoring because they can have side effects. Your specialist will tailor the treatment plan to you, and it may change over time. You will be seen regularly to adjust the plan as needed.

When is surgery considered?

In rare cases, a procedure called angioplasty (using a small balloon to open a narrowed artery) or surgery may be needed to restore blood flow through a severely narrowed or blocked artery. This is considered when medical treatment is not enough or in an emergency situation.

Living with this condition

Living with a chronic illness can be unpredictable. Some days you will feel well; other days you may need to rest. It helps to plan around your energy, ask for help when needed, and keep a flexible routine.

Lifestyle tips

• Avoid smoking in any form — it is one of the most damaging things for your blood vessels.
• Get gentle regular activity when you can, such as walking or stretching.
• Stay on top of your medications and appointments.
• Learn your personal warning signs — know when to rest and when to seek help.

Diet and exercise

Aim for a heart-healthy diet with plenty of fruits, vegetables, whole grains, and lean proteins. Try to keep your blood pressure in a healthy range. Light to moderate exercise, such as walking or swimming, is usually safe and beneficial. Check with your healthcare team before starting any new exercise program.

Mental health and emotional wellbeing

It is completely normal to feel anxious, stressed, or low when you are living with a chronic illness. These feelings can be managed. Talk to your doctor or nurse about how you are feeling. If you ever feel in crisis or have thoughts of harming yourself, reach out for urgent help — call your local emergency number or a mental health crisis line right away.

Prevention

Because the exact cause is unknown, there is no known way to prevent Takayasu arteritis. However, early diagnosis, consistent treatment, and a healthy lifestyle can help reduce the risk of serious complications.

Vaccines

Keep your routine vaccinations up to date. Because some treatments for Takayasu arteritis can weaken the immune system, talk to your doctor before receiving any live vaccine. Your care team can tell you which vaccines are safe for you.

Screening programmes

If you have a close family member with Takayasu arteritis, your doctor may check your blood pressure and listen for unusual blood vessel sounds during routine visits, but there is no standard screening test.

Complications

If left untreated

• High blood pressure that is difficult to control and can lead to kidney damage
• Aneurysm — a bulging, weakened artery that can tear (dissect)
• Stroke — if arteries to the brain are affected
• Heart attack or heart failure — if arteries to the heart are involved
• Vision loss or sudden blindness

Long-term outlook

With early diagnosis and ongoing specialist care, many people with Takayasu arteritis live full, productive lives. The disease can be unpredictable, but treatment can greatly reduce inflammation and the chance of serious complications. Your medical team will work with you to keep the condition as stable as possible and help you maintain good quality of life.
