Other Autoimmune Diseases

What is Other Autoimmune Diseases?

Autoimmune diseases happen when your immune system mistakenly attacks your own healthy cells and tissues. Your immune system is designed to protect you from bacteria, viruses, and other invaders. In autoimmune conditions, it turns against your body instead.

There are more than 80 different types of autoimmune diseases. They can affect almost any part of your body, including your joints, skin, organs, and glands. Some common autoimmune diseases include rheumatoid arthritis, lupus, type 1 diabetes, psoriasis, and inflammatory bowel disease. Many people with one autoimmune disease develop others over time.

These conditions range from mild to severe and can affect people of all ages. Women are more likely to develop autoimmune diseases than men. Early detection through blood testing helps you understand what is happening in your body and start treatment sooner.

Symptoms

Chronic fatigue that does not improve with rest
Joint pain, stiffness, or swelling
Skin rashes or changes in skin appearance
Recurring fevers or feeling generally unwell
Muscle weakness or pain
Digestive problems like bloating, diarrhea, or abdominal pain
Brain fog or difficulty concentrating
Unexplained weight changes
Hair loss or thinning
Numbness or tingling in hands and feet

Many people experience mild symptoms for years before getting diagnosed. Some people have periods where symptoms flare up and times when they feel better. Early symptoms can be vague and easy to dismiss as stress or aging.

Causes and risk factors

Autoimmune diseases develop when your immune system loses its ability to tell the difference between your own cells and foreign invaders. Researchers believe a combination of genetics and environmental triggers causes this to happen. If someone in your family has an autoimmune disease, you have a higher risk of developing one too. Common triggers include infections, certain medications, toxins, and chronic stress.

Lifestyle factors play a significant role in autoimmune disease development and progression. Poor gut health, chronic inflammation, vitamin D deficiency, and exposure to environmental toxins can all contribute. Women of childbearing age face the highest risk, possibly due to hormonal influences. Smoking, obesity, and a diet high in processed foods may increase your risk or worsen existing symptoms.

How it's diagnosed

Diagnosing autoimmune diseases often requires multiple blood tests to detect specific antibodies and markers of inflammation. Your doctor will review your symptoms, family history, and physical exam findings. Blood tests help confirm the diagnosis and rule out other conditions with similar symptoms.

Rite Aid offers testing for thyroid peroxidase antibodies, which can be elevated in various autoimmune conditions including rheumatoid arthritis, lupus, and type 1 diabetes. This antibody test helps identify immune system overactivity even when thyroid function appears normal. Getting tested regularly at a Quest Diagnostics location near you helps track your immune health over time.

Treatment options

Regular low-impact exercise like walking, swimming, or yoga
Stress management through meditation, deep breathing, or therapy
Adequate sleep of 7 to 9 hours per night
Immunosuppressive medications to reduce immune system activity
Disease-modifying drugs specific to your condition
Pain relievers and anti-inflammatory medications
Vitamin D and omega-3 supplements to reduce inflammation
Probiotics to support gut health and immune balance

Frequently asked questions

The most common autoimmune diseases include rheumatoid arthritis, lupus, type 1 diabetes, psoriasis, multiple sclerosis, and inflammatory bowel disease. Hashimoto's thyroiditis and Graves' disease affect the thyroid gland. Celiac disease damages the small intestine when you eat gluten. Each condition affects different parts of the body but all involve the immune system attacking healthy tissue.

Blood tests can detect many autoimmune diseases by identifying specific antibodies and inflammation markers. However, no single test diagnoses all autoimmune conditions. Your doctor may order multiple tests based on your symptoms. Some autoimmune diseases require tissue biopsies or imaging studies in addition to blood work for a definitive diagnosis.

Women develop autoimmune diseases about twice as often as men, though the exact reason remains unclear. Hormones like estrogen may influence immune system activity. X chromosome genes related to immunity may play a role since women have two X chromosomes. Pregnancy and menstrual cycles cause immune system changes that might trigger autoimmune responses in susceptible women.

Yes, having one autoimmune disease increases your risk of developing others. This happens because the underlying immune system dysfunction can affect multiple organs and tissues. For example, people with rheumatoid arthritis often develop thyroid problems. Regular blood testing helps catch new autoimmune conditions early before symptoms become severe.

Elevated thyroid peroxidase antibodies with normal thyroid function may indicate another autoimmune condition like lupus, rheumatoid arthritis, or type 1 diabetes. TPO antibodies show general immune system overactivity, not just thyroid problems. Your doctor should investigate other symptoms and run additional tests. High TPO antibodies may also predict future thyroid disease even if your thyroid works normally now.

Most autoimmune diseases cannot be cured, but they can be managed effectively with treatment. The goal is to reduce immune system activity, control inflammation, and prevent organ damage. Many people achieve remission where symptoms disappear for extended periods. Lifestyle changes like diet, stress management, and sleep can significantly improve outcomes and quality of life.

Many people with autoimmune diseases benefit from avoiding gluten, dairy, processed sugar, and refined grains. Nightshade vegetables like tomatoes and peppers trigger symptoms in some people. Processed foods with additives and preservatives can worsen inflammation. An elimination diet helps identify your personal trigger foods. Work with a healthcare provider before making major dietary changes.

Most doctors recommend blood tests every 3 to 6 months to monitor autoimmune disease activity and treatment effectiveness. More frequent testing may be needed if you start new medications or have symptom flares. Rite Aid offers twice yearly testing that helps you track antibody levels and inflammation markers over time. Regular monitoring catches changes early before they cause serious problems.

Chronic stress is a known trigger for autoimmune disease flares and may contribute to disease development. Stress hormones like cortisol affect immune system function and increase inflammation. Many people notice their symptoms worsen during stressful periods. Managing stress through meditation, exercise, therapy, and adequate sleep can reduce flare frequency and severity.

About 70 percent of your immune system lives in your gut, making gut health critical for autoimmune conditions. Leaky gut syndrome allows undigested food particles and toxins into your bloodstream, triggering immune responses. Poor gut bacteria balance promotes inflammation and immune dysfunction. Probiotics, fermented foods, and a whole-foods diet support gut healing and may reduce autoimmune symptoms.
