At Beacon Clinic in North Idaho, our rheumatology team is dedicated to helping patients understand and manage complex conditions that affect the immune system and overall health. Among the most misunderstood are autoimmune diseases — conditions in which the body’s own defense system turns against itself.
While the immune system is designed to protect us from infections and illness, autoimmune diseases occur when it becomes overactive or misdirected, attacking healthy tissues instead of harmful invaders. This can lead to chronic inflammation, pain, and damage to various organs and systems throughout the body.
Let’s explore what autoimmune diseases are, why they happen, and how they are diagnosed and treated.
What Are Autoimmune Diseases?
The immune system is a complex network of cells and proteins that defend the body against bacteria, viruses, and other harmful substances. In autoimmune diseases, this system becomes confused and mistakenly identifies healthy tissues as threats. As a result, the immune system begins to attack parts of the body such as:
- Joints
- Skin
- Muscles
- Organs
- Blood vessels
There are more than 80 known autoimmune diseases, each affecting different parts of the body. Some of the most common include:
- Rheumatoid arthritis (RA): like osteoarthritis, RA affects the joints, causing pain, swelling, and stiffness; RA afflict about 1.5 million people in the US
- Systemic lupus erythematosus (lupus): can affect multiple organs, including the skin, kidneys, and heart; like RA, it affects about 1.5 million people in the US
- Psoriatic arthritis: causes joint inflammation, which results in pain and swelling; it affects roughly 1.5 to 3 million people in the US, and about one third of those who get psoriatic arthritis are those who suffer from psoriasis
- Sjogren’s syndrome: affects moisture-producing glands, leading to dry eyes and dry mouth; though less well-known than RA, it affects almost 4 million people in the US
- Ankylosing spondylitis: primarily affects the spine and can cause stiffness and reduced mobility, affecting up to 3 million people in the US
Why Do Autoimmune Diseases Happen?
The exact cause of autoimmune diseases is not fully understood, but researchers believe they can develop from a combination of factors, including:
- Genetics: Certain autoimmune diseases tend to run in families. While genetics alone don’t determine whether someone will develop a condition, they can increase susceptibility.
- Environmental Triggers: Factors such as infections, toxins, or exposure to certain chemicals may trigger an autoimmune response in individuals who are already at risk.
- Hormonal Factors: Autoimmune diseases are more common in women, suggesting that hormones may play a role in how the immune system functions.
- Immune System Dysregulation: In some cases, the immune system simply malfunctions, becoming overactive without a clear external cause.
It’s important to understand that autoimmune diseases are not caused by a single factor, and they are not contagious. Furthermore, while autoimmune conditions can arise at any age, they are more commonly found in individuals over the age of 50, suggesting that developing an autoimmune condition is more likely to occur in those whose immune system has been weakened by natural degeneration or from extended exposure to environmental factors or lifestyle behaviors (such as diet, pollution, medications, etc.).
Common Symptoms of Autoimmune Diseases
Because autoimmune diseases can affect many different parts of the body, symptoms vary widely. However, many share common signs, such as:
- Persistent fatigue
- Joint pain or swelling
- Muscle aches
- Low-grade fever
- Skin rashes
- Digestive issues
- Dry eyes or mouth
One of the challenges in diagnosing autoimmune diseases is that symptoms often develop gradually and may come and go, making them easy to overlook, dismiss, or misattribute to other conditions.
How Are Autoimmune Diseases Diagnosed?
At Beacon Clinic, our rheumatology specialists use a comprehensive approach to diagnosis. This may include:
- A detailed review of symptoms and medical history
- Physical examination
- Blood tests to check for markers of inflammation and autoimmunity
- Where appropriate, imaging tests such as X-rays, ultrasound, or MRI
- Specialized tests to help identify specific conditions
Because autoimmune diseases can mimic other illnesses, a careful and thorough evaluation is essential for an accurate diagnosis to rule out alternative causes of symptoms.
Treatment and Management
While there is currently no cure for most autoimmune diseases, many effective treatments are available to help manage symptoms, reduce inflammation, and improve quality of life. For example, depending on the condition, treatment options may include:
- Anti-inflammatory medications
- Disease-modifying antirheumatic drugs (DMARDs)
- Biologic therapies that target specific parts of the immune system
- Corticosteroids to control flares
- Lifestyle changes, such as regular exercise, stress management, and a modified diet to remove inflammation triggers or add anti-inflammatory foods or supplements
The goal of treatment is to reduce symptoms, prevent flare-ups, and protect the body from long-term damage.
