What are the most common autoimmune disorders?
There are over 80 autoimmune diseases. These all affect your body in different ways. Some of the most common types of autoimmune diseases are listed here.
What causes autoimmune disorders?
Your immune system usually protects your body from disease and infection. But when you have an autoimmune disease, your immune system mistakenly attacks your own cells, tissues, and organs. This leads to inflammation and damage to the affected organs or tissues. It’s common to have more than one autoimmune disease at a time, due to the similar processes involved.
It’s thought that most autoimmune disorders are caused by a combination of genetic and other (environmental) factors. Autoimmune diseases can run in families due to genes that you inherit from your parents.
But other factors can be involved in triggering the condition. These include viruses, your diet, and exposure to certain chemicals or substances.
Autoimmune diseases can affect anyone, at any age. But many are more common in people with female anatomy than male.
What are the symptoms of autoimmune disorders?
Some symptoms can be common to several autoimmune diseases. These include:
- fatigue (extreme tiredness and exhaustion)
- pain – due to inflammation or nerve damage
- skin rashes
- aching, swollen, or stiff joints
Other symptoms will be specific to the condition you have. For example, you might have:
- patches of inflamed skin with psoriasis
- digestive and bowel symptoms with IBD
- vision, balance, and mobility problems with multiple sclerosis
An autoimmune condition may affect just one part of your body. Or it may affect several different organs or body systems – like your skin, joints, and lungs. For many autoimmune disorders, symptoms come and go. This means you might have periods where you feel better (remission). Then, you have periods where your symptoms flare up again and you need treatment to get it under control.
How are autoimmune disorders treated?
Autoimmune disorders can’t be cured – they are something that you will have for life. This means that treatment for autoimmune disorders usually focuses on:
- managing symptoms
- preventing complications
- preventing further damage to affected areas
This may involve taking medicines to reduce inflammation and dampen down the immune system. For example, these may include non-steroidal anti-inflammatory drugs (NSAIDs), steroids, and immunosuppressants. For some conditions, you may be able to take disease-modifying therapies, which stop the disease progressing.
It may also help to make some lifestyle changes if you have an autoimmune disorder. Keeping active, following a healthy diet, not smoking, and managing stress can all help to reduce symptoms.
Having an autoimmune disorder can increase your risk of certain other health conditions, like heart disease. Your doctor will monitor you to make sure you get any treatment you need.
What support is available for autoimmune disorders?
It can be difficult living with the day-to-day effects of autoimmune conditions. Dealing with these problems can affect your mood. Depression and anxiety are common in people with autoimmune disorders.
Learning the best way to manage your condition and getting support can make all the difference. Talking to other people in a similar situation may help too.
There are organisations that offer support and advice for people with autoimmune conditions. Your doctor can advise you on managing symptoms and accessing appropriate treatment.
