Autoimmune diseases are a heterogeneous group of more than 80 conditions in which the immune system, through multiple and partially understood mechanisms, attacks the body's own tissues instead of protecting them; collectively they affect 5-10% of the world's population with a marked female predominance, an observation whose underlying mechanism (the role of estrogens, the X chromosome, the microbiota, other factors) remains the subject of active research. The main autoimmune diseases include Hashimoto's thyroiditis, Graves' disease, systemic lupus erythematosus, rheumatoid arthritis, multiple sclerosis, type 1 diabetes, celiac disease, inflammatory bowel disease (Crohn's disease and ulcerative colitis), psoriasis, ankylosing spondylitis, scleroderma, myositis, vitiligo, pernicious anemia, and many others.
Autoimmune diseases tend to coexist in the same person and in the same family: a person with one autoimmune disease has an increased risk of developing others (for example, Hashimoto's thyroiditis + celiac disease + vitiligo is a frequent combination; lupus + Sjögren's + thyroiditis is another). This suggests a shared genetic and environmental predisposition.
Treatment varies radically depending on the disease and its severity: from hormone replacement in Hashimoto's thyroiditis, to immunosuppressants in lupus and multiple sclerosis, to targeted biologic therapies in many (anti-TNF, anti-IL, anti-CD20, etc.). Specialized medical treatment is essential; self-supplementation must NEVER replace it.
Vitamin D: subclinical deficiencies are very common in autoimmunity; correction with 2,000-4,000 IU/day has modest but consistent support for reducing the activity of several autoimmune diseases and preventing their development.
Omega-3 EPA/DHA: adjunctive systemic anti-inflammatory effects.
Mediterranean diet: supported by cohorts for rheumatoid arthritis and other inflammatory diseases.
Gluten-free diet in celiac disease (mandatory) and possibly useful in other autoimmune diseases with associated sensitivity (questioned, individualize).
Specific probiotics: growing support via the microbiota-immunity axis.
Chronic stress management: reduces the frequency of flares.
Sufficient, good-quality sleep.
Regular adapted physical exercise: supported for improving fatigue and well-being in multiple autoimmune diseases.
Smoking cessation: especially important in lupus, RA, IBD, and multiple sclerosis.
Selenium: supported in autoimmune thyroiditis (Hashimoto's, Graves' with ophthalmopathy).
Immunostimulant supplements: echinacea, astragalus, ganoderma at high doses, beta-glucans at high doses. They may theoretically exacerbate autoimmunity, although the clinical data are limited; it is advisable to avoid them as a precaution in active autoimmune diseases.
Herbs with potent hormonal effects: may disturb immune balance.
Megadoses of antioxidants: may interfere with the efficacy of immunosuppressants and with necessary immune mechanisms.
St. John's wort: numerous drug interactions (contraceptives, immunosuppressants, anticoagulants, antidepressants).
Any "alternative treatment" that claims to replace medical treatment: dangerous.
There is growing evidence that gut dysbiosis contributes to several autoimmune diseases and that modulating the microbiota (a diverse, plant-rich diet, fermented foods, specific probiotics, prebiotic fiber) has a modest but encouraging adjunctive effect.
Any suggestive symptoms (inflammatory joint pain, severe unexplained fatigue, persistent skin lesions, thyroid abnormalities, dry eyes or mouth, abdominal pain with chronic diarrhea, unexplained weight loss, focal neurological deficits, recurrent fever without a cause), or a strong family history, require specialized medical evaluation (rheumatology, endocrinology, gastroenterology, dermatology, or neurology depending on the presentation).
Autoimmune diseases are complex and require specialized medical treatment individualized for each condition. Supported complementary interventions (Mediterranean diet, omega-3, vitamin D if deficient, stress management, adapted exercise, no tobacco, adequate sleep, microbiota modulation) are valuable adjuncts but never substitutes. Immunostimulant supplements should be avoided by default. Research is active, with new biologic therapies that are changing prognoses.
