People prone to autoimmune diseases often have a genetic link, are female (especially young to middle-aged women), have a history of infections or tissue damage, and may experience triggers from environmental factors like certain chemicals, stress, or even diet, with some ethnic groups having higher risks for specific conditions. Having one autoimmune disease also increases the risk of developing another.
As a result, your body sets off a reaction that damages or destroys normal tissues. The exact cause of autoimmune disorders is unknown. One theory is that some microorganisms (such as bacteria or viruses) or medicines may trigger changes that confuse the immune system.
You know you might have an autoimmune disease by noticing persistent, unexplained symptoms like extreme fatigue, joint pain/swelling, skin rashes, digestive issues, recurring fevers, or numbness/tingling, but a doctor uses a combination of your medical history, physical exam, and blood tests (checking for inflammation and autoantibodies), sometimes followed by imaging or a biopsy, for an official diagnosis.
Women have up to a fourfold increase in risk for autoimmune disease compared to men. Many explanations have been proposed, including sex hormones, the X chromosome, microchimerism, environmental factors, and the microbiome.
Why are autoimmune and allergic diseases increasing? Our genes haven't changed much in the last 70 years, but our current environment is vastly different. One dominant idea in the field is called the hygiene hypothesis. People noticed that issues with our immune systems started increasing when we improved sanitation.
The "worst" autoimmune diseases are subjective but often cited for severity, impact on life expectancy, or organ damage, with top contenders including Giant Cell Myocarditis (highly fatal), Vasculitis (damages blood vessels), Systemic Lupus Erythematosus (Lupus) (multi-organ), Multiple Sclerosis (MS) (nervous system), and Type 1 Diabetes (pancreas, life-long management). Other severe conditions include Scleroderma and Myasthenia Gravis.
COVID infection has been linked to higher risk of autoimmune disorders, including rheumatoid arthritis and type 1 diabetes.
Autoimmune diseases (ADs) affect approximately 5% of the world population [1, 2]. The age at onset varies widely depending on the disease. For example, sixty-five percent of patients with systemic lupus erythematosus (SLE) start manifesting their symptoms between ages 16 and 55 [3].
Nevertheless, the onset of at least 50% of autoimmune disorders has been attributed to “unknown trigger factors”. Physical and psychological stress has been implicated in the development of autoimmune disease, since numerous animal and human studies demonstrated the effect of sundry stressors on immune function.
If you have a positive ANA test, an ENA test can check the blood for the presence of antinuclear antibodies that are known to be markers of certain diseases. The ENA test can help your health care team and your rheumatologist diagnose autoimmune diseases such as: Lupus.
The antinuclear antibody (ANA) immunofluorescence assay (IFA) is a first-line screening test for patients with a suspected autoimmune disease.
Micronutrient Deficiencies: deficiencies in vitamin D, vitamin C, selenium, zinc, antioxidants, and omega-3 are linked to the deterioration of the immune system's function, the emergence of inflammation, and the health condition of patients with autoimmune diseases.
Ways diet can help improve your condition
Common symptoms of autoimmune disease include:
Also, infections like the flu virus, mono (mononucleosis), and measles can weaken the immune system for a brief time. Your immune system can also be weakened by smoking, alcohol, and poor nutrition.
Autoimmune diseases do tend to run in families, which means that certain genes may make some people more likely to develop a problem. Viruses, certain chemicals, and other things in the environment may trigger an autoimmune disease if you already have the genes for it.
Chronic inflammation – Emotional stress—especially unresolved anger—triggers inflammatory responses. This persistent state of inflammation is a key factor in autoimmune diseases.
Patients experiencing chronic fatigue related to autoimmune conditions often describe their symptoms as more than just feeling tired during the day. This is significant exhaustion that impacts quality of life and makes it difficult to function on a normal basis.
The "worst" autoimmune diseases are subjective but often cited for severity, impact on life expectancy, or organ damage, with top contenders including Giant Cell Myocarditis (highly fatal), Vasculitis (damages blood vessels), Systemic Lupus Erythematosus (Lupus) (multi-organ), Multiple Sclerosis (MS) (nervous system), and Type 1 Diabetes (pancreas, life-long management). Other severe conditions include Scleroderma and Myasthenia Gravis.
As many as 4 out of 5 of those people are women. Rheumatoid arthritis, multiple sclerosis and scleroderma are examples of autoimmune disorders marked by lopsided female-to-male ratios. The ratio for lupus is 9 to 1; for Sjogren's syndrome, it's 19 to 1.
Early warning signs of lupus often include extreme fatigue, unexplained fever, joint pain/swelling, skin rashes (especially a butterfly-shaped one on the face), hair loss, mouth sores, and Raynaud's phenomenon (fingers/toes turning white or blue in the cold). Because these symptoms mimic other conditions, lupus can be hard to diagnose early, but they often come in waves (flares) and affect various body systems.
People with Sjögren's might experience symptoms like:
Some infections may increase the chance of developing an autoimmune disease. One virus in particular - Epstein Bar virus (EBV) – has been studied across various autoimmune diseases, including SLE, Sjögren's, and multiple sclerosis. This virus is highly prevalent and is known to cause mononucleosis in young adults.
Taking vitamin D is recommended because vitamin D plays a role in immune regulation and may help reduce autoimmune activity. Many people with autoimmune diseases are deficient in this vitamin, and I am one of them. Eat more foods with omega-3 fatty acids, which can be found in fish, nuts, seeds, and plant oils.
PASC is characterized by a variety of long-lasting symptoms, with the most common being shortness of breath, headache, fatigue, cognitive dysfunction (memory impairment and lack of concentration), anxiety, myalgia, joint pain, smell and taste dysfunction, cough, insomnia, rhinorrhea (Lopez-Leon et al., 2021).
