When you’re dealing with an autoimmune disease, it can feel confusing and frustrating, because the symptoms don’t always add up in a clear way.
This article will discuss what autoimmune conditions really are, why they seem to be showing up more often, and the kinds of symptoms people commonly experience.
You’ll also see how doctors go about identifying an autoimmune condition, and what kinds of natural, supportive steps may help calm and balance the immune system.
What Is Autoimmune Disease?
An autoimmune disease happens when the immune system, your body’s defense team, mistakenly targets your own cells.
It’s not simply an “overactive” immune system; it’s a misdirected immune response. Immune cells and autoantibodies drive inflammation in places they shouldn’t.
Autoimmune disorders can be organ-specific (like the thyroid or pancreas) or systemic (affecting the whole body). There are between 80 and 150 recognized conditions across this spectrum [1].
Why Autoimmune Conditions Are Becoming More Common
In the United States, newer estimates suggest that about 4.6% of people, roughly 15 million, are living with at least one autoimmune disease, with women affected more often than men [2].
These numbers explain why doctors and researchers are paying more attention to this topic.
One reason for the increase is better detection. Electronic health records and clearer definitions help track cases across various conditions, and routine antibody testing is more common now.
Environmental factors also play a role. Research shows that long-term exposure to air pollution raises the risk for some autoimmune diseases, like lupus and rheumatoid arthritis [3]. Inhaling pollutants can increase immune-driven inflammation.
Our diets have changed, too. Reviews indicate that ultra-processed foods and certain additives might harm the gut microbiome and intestinal barrier, potentially affecting immune balance [4].
We are also identifying more cases because of greater awareness. New national efforts, such as the NIH Office of Autoimmune Disease Research, aim to coordinate data across institutes [5]. This improves tracking and helps observe trends over time.
Globally, patterns differ by country and healthcare access, but the overall trend is the same: more recognition and, in some areas, actual increases driven by environmental and lifestyle factors. Understanding these causes helps improve research and allows for earlier recognition, so people can receive support sooner.
Common Types of Autoimmune Disease
Autoimmune diseases can involve nearly any organ system; below are common autoimmune disorders grouped by the organ system in which the immune response is most active.

- Systemic lupus erythematosus (SLE)
- Myositis
- Psoriatic arthritis
Affecting Skin and Blood Vessels
- Psoriasis
- Dermatomyositis
- Scleroderma (systemic sclerosis)
- Sjögren’s syndrome
- Vasculitis
- Vitiligo
Affecting the Digestive System

This isn’t an exhaustive list. If you live with an autoimmune disease, know that many people find clarity by first understanding which system is involved and then building a care plan with their doctors.
7 Major Causes of Autoimmune Disease
Doctors and researchers still don’t know the exact causes of autoimmune disease.
However, we do know that certain risk factors and triggers may contribute to this condition. These don’t cause the condition by themselves, but they can make it more likely to develop in someone who is already more vulnerable.
1) Family History and Genes
Autoimmune disease often runs in families. Having certain genes raises your risk, but genes alone are not enough. Something in your environment or lifestyle usually needs to “switch on” these genes [6].
2) Infections
Some infections can confuse the immune system. A virus or bacteria may look a little too similar to your own tissue, and the immune system may start reacting to both. This helps explain why certain infections are linked with autoimmune disease later in life.
3) Gut Health and the Microbiome
Most of your immune system sits along your gut lining. If the gut becomes leaky or the balance of good and bad bacteria shifts, your immune system may start overreacting to things it would normally tolerate. Over time, this can add stress that contributes to autoimmune activity.
4) Environmental Exposures
Every day exposures matter. Cigarette smoke, industrial chemicals, and long-term air pollution can irritate the immune system. By themselves, they don’t cause autoimmune disease, but they can act as triggers when other risk factors are already present.
5) Stress, Sleep, and Daily Rhythm
Chronic stress can wear down the body. Over time, this may result in Adrenal Fatigue, in which the stress-response system strains to keep up. When this occurs, you may feel tired, foggy, and have a difficult time sleeping.
When your sleep or daily pattern is disrupted, your immune system may become more reactive, making you more susceptible to illness.
6) Hormonal Changes
Hormones strongly influence how the immune system works. This is why women are more likely to develop an autoimmune disease, especially during times of change like puberty, pregnancy, or menopause [7]. Shifts in estrogen, progesterone, or testosterone can tip the balance toward more inflammation.
7) Other Health and Lifestyle Factors
- Nutrition – Diets low in whole, nutrient-rich foods may weaken the immune system’s ability to stay balanced.
- Weight – Extra body fat releases inflammatory signals that add stress to the immune system.
- Other conditions – Having one autoimmune condition makes it more likely to develop another, since many of the same risk factors overlap [8].
Symptoms and Early Warning Signs of Autoimmune Disease
Autoimmune disease can look different from person to person, but there are common patterns worth knowing.
Many symptoms overlap with other conditions, so the key is to notice when several signs appear together or when they keep coming back without a clear reason.
| Category | Common Symptoms |
|---|---|
| Energy and Cognitive | Fatigue that feels out of proportion to your day, brain fog (trouble focusing or finding words), memory slips, and mood changes that don’t feel like you. |
| Musculoskeletal | Joint pain, swelling, morning stiffness, and muscle aches or soreness without a clear injury. |
| Digestive | Bloating, abdominal pain, diarrhea or constipation, and new food sensitivities, sometimes with a “feeling unwell after meals” pattern. |
| Skin, Hair, and Nails | Rashes or hives, sensitivity to sunlight that brings on a rash or fatigue, hair thinning or sudden shedding, and brittle or ridged nails. |
| Hormonal and Metabolic | Unexplained weight changes, irregular menstrual cycles, shifts in blood sugar, and feeling unusually cold or hot. |
| Immune and General | Low-grade fever (slightly elevated temperature), swollen lymph nodes (small immune glands), and infections that keep coming back. |
| Neurological | Numbness or tingling in the hands or feet, dizziness, lightheadedness, and occasional balance changes. |
| Red Flags to Notice (Seek a Healthcare Provider) | Persistent fevers, severe or rapidly spreading rashes, sudden hair loss, fainting, or worsening nerve pain. |
These are common autoimmune symptoms, not a diagnosis. Having one or two of these symptoms doesn’t automatically mean you have an autoimmune disease.
Many of them are nonspecific and can overlap with other health concerns. The value comes from noticing patterns over time, so you can bring a clearer picture to your healthcare provider.
How Chronic Stress and the NEM System Trigger Autoimmune Conditions
Chronic stress does not directly cause autoimmune disease, but it can push your body out of balance.
The NeuroEndoMetabolic (NEM) Stress Response System shows how this happens and why stress can affect your immune health.
When stress appears, the brain tells the adrenal glands through the HPA axis (hypothalamic-pituitary-adrenal pathway) to release cortisol. Cortisol gives you energy and helps calm the immune system so it does not overreact.
Short-term stress is usually manageable. But when stress goes on for too long, cortisol levels can first rise and later fall, which upsets the body’s natural way of keeping the immune system steady.
Here’s how stress can affect the six NEM circuits:
- Hormone circuit: Made up of the adrenal, thyroid, and reproductive glands. When stress hormones continue long-term, they pull resources from other hormones, causing them to dysregulate, in turn dysregulating the immune system.
- Inflammation circuit: Involves the gut, immune system, and microbiome. Constant stress keeps the immune system active, which feeds inflammation, and makes it harder for the body to tell the difference between its own tissues and outside threats.
- Neuroaffect circuit: Includes the brain, nervous system, and gut connection. Worry, poor sleep, and racing thoughts keep the body alert, which adds to inflammation.
- Bioenergetics circuit: Controlled by the thyroid, pancreas, and liver. Stress can throw off blood sugar and energy balance, which also changes how the immune system responds.
- Detoxification circuit: Involves the liver and immune system. When waste removal slows down under stress, toxins and irritants can build up and stir the immune system.
- Cardionomic circuit: Connects the heart, adrenals, and nervous system. Stress can cause repeated jumps in heart rate and blood pressure, like constant alarms that keep the immune system on edge.
When these circuits are under strain, it creates conditions where autoimmune disease is more likely to show up or flare in someone already at risk.
Genes and outside triggers still play a role, but stress can create multiple low-grade dysfunctions in the body that can build up into autoimmune activity.
How Providers Identify Autoimmune Diseases
Identifying an autoimmune disease is rarely about a single test. It’s about connecting your story, what doctors find on exams, and what the labs and images show, so the pattern makes sense.
First Steps: History and Exam
Health history: Doctors talk through your symptoms, when they started, what makes them better or worse, and whether autoimmune conditions run in your family. One clear timeline often tells them where to look next.- Physical exam: Doctors look for real-world clues such as rashes, joint swelling, thyroid enlargement, or changes in nerve function, since these signs can point toward a specific immune system disorder.
- Differential diagnosis: Because many illnesses mimic autoimmune conditions, doctors rule out look-alikes first and then confirm the most likely cause with focused testing.
Conventional Medical Testing
- Autoantibody panels (immune “markers”): ANA, anti-dsDNA, anti-CCP, and thyroid antibodies look for proteins your immune system makes that react to your own tissues. Each marker nudges the determination toward certain autoimmune patterns.
- Inflammation markers: ESR and CRP reflect the level of inflammation in your body. They’re helpful context, not proof—high numbers have many causes, and normal numbers don’t exclude autoimmune disease.
- Imaging studies: X-ray, MRI, CT, or ultrasound are chosen based on symptoms to reveal joint changes, organ swelling, or tissue findings that support the overall picture.
Advanced and Specialized Evaluations
Some clinics, like the Lam Clinic, add these when the basics don’t explain the full story:
- Thyroid ultrasound: Uses sound waves to map the thyroid and identify nodules or enlargement, providing a clear baseline for comparison over time.
- Comprehensive blood draws: When appropriate, panels can assess micronutrients, hormones, infections, toxins, gut health, and cardiovascular markers—factors that may influence immune balance and chronic inflammation.
- Functional testing: Includes organic acids, comprehensive stool analysis, mycotoxin screening, and environmental toxin panels. These tests can uncover hidden imbalances in digestion, detoxification pathways, or toxin exposure, which can trace symptoms back to their root causes that standard labs may miss.
- Allergy skin testing: Finds immediate (IgE) reactions to pollen, pets, molds, or foods. It doesn’t identify autoimmunity, but it can separate allergic flares from autoimmune symptoms.
- Sudomotor neuropathy testing: Measures sweat gland nerve function to screen for small-fiber or autonomic nerve changes that can travel alongside metabolic or immune issues.
- Pulmonary function testing (PFTs): Evaluates airflow and oxygen exchange when breathing symptoms or known autoimmune conditions suggest lung involvement.
- Liver elastography (“liver scan”): A quick, non-invasive way to estimate liver stiffness (fibrosis) and fat (steatosis) when medications, metabolic factors, or suspected autoimmune liver conditions raise questions.
- Nervous system testing: Looks at how your body balances “fight-or-flight” with “rest-and-repair,” offering insight into fatigue, dizziness, or stress sensitivity that can accompany an autoimmune condition.
No single number determines the condition. Doctors look for a consistent pattern across your history, exam, and tests over time, and they move at a careful pace so you get clarity without unnecessary worry.
While many clinics offer follow-up, Lam Clinic takes ongoing support further. Your care team stays actively involved, whether you’re seen in person or online. You’ll have direct access to your doctor, health coach, nutritionist, and Care Coordinator, so you’re never left to figure things out on your own.
Natural Ways to Support the Immune System
When you live with an autoimmune disease, it can sometimes feel like your body is always on guard.
Here are some natural strategies that can help guide your immune system toward balance and resilience:
Nutritional Approaches
The Autoimmune Protocol (AIP) Diet
The AIP diet has been used for nearly two decades. It looks similar to a paleo-style eating and shares features with the early stages of the Adrenal Fatigue diet.
The idea is simple: remove foods that often irritate the gut, give your body time to calm down, and then add foods back in one by one to see what you tolerate best.
- Phase 1: Elimination (30–90 days)
This stage removes grains, legumes, nuts, seeds (and their oils or spices), dairy, eggs, nightshades like tomatoes and peppers, processed oils, added sugars, alcohol, coffee, and certain medications such as NSAIDs (but always speak with your doctor before adjusting any medicines).
- Phase 2: Reintroduction
After symptoms improve, you slowly bring foods back in. Start with a tiny portion, watch for changes, then try a normal serving. If you feel fine, you can keep that food. If symptoms appear, pause it and try again later. Choosing a time when you are well-rested and less stressed helps you get clearer results.
Even with the restrictions, many foods remain on the table: colorful vegetables (excluding nightshades), fruits in moderation, quality meats, olive oil, herbs, bone broth, non-dairy fermented foods, vinegar, tea, and natural sweeteners such as honey or maple syrup.
Mediterranean-Style Eating
For long-term use, the Mediterranean diet pattern is often easier. It highlights vegetables, olive oil, fish, nuts, legumes, and whole grains if tolerated. This way of eating supports the gut microbiome and helps calm inflammation.
Simpler Elimination Trials
If a full AIP plan feels overwhelming, even a short elimination of one or two common triggers can be valuable. Sometimes just removing dairy or gluten for a few weeks and then reintroducing them is enough to notice a difference.
Key Nutrients and Supplements
Nutrition forms the base, but supplements can fill in gaps where diet or testing shows a need.
Essential Vitamins and Minerals
- Vitamins A, C, D, and E help maintain a strong gut lining, defend against oxidative stress, and support healthy immune signaling.
- Zinc and magnesium contribute to immune balance and overall cell health.
- B vitamins assist with energy production and brain function.
Our Adrenal Daily Nutrient combines these essentials with supportive blends for digestion, superfoods, immunity, adrenal support, and gentle detoxification.
Omega-3 Fatty Acids
Omega Max (MaxSimil®) provides highly absorbable omega-3s, including EPA, DHA, and DPA. These healthy fats help resolve inflammation and strengthen cell membranes, which are vital for immune communication.
Probiotics
The gut and immune system are deeply connected. Adrebiotics offers a multi-strain blend of beneficial bacteria to encourage balance in the gut and help the immune system respond more calmly.
Glutathione
Known as the body’s master antioxidant, glutathione protects cells, supports the liver, and recycles vitamin C. LipoNano Glutathione combines glutathione with vitamin E, B12, and other nutrients to strengthen natural defense systems.
Medical Note: This information is for general wellness only and shouldn’t replace medical advice. Since everyone’s health needs are different, talk with your healthcare provider before starting or changing any supplements, especially if you’re on medication, pregnant, nursing, or managing a condition.
Lifestyle Foundations
- Sleep is your immune reset button. Aim for consistent nights of seven to nine hours whenever possible.
- Movement keeps circulation flowing and helps immune cells travel where they need to go. Gentle, regular activity like walking, stretching, or light strength work is often helpful.
- Stress management also makes a difference. Simple practices like deep breathing, prayer, mindfulness, or spending time outdoors can calm the stress response and lower inflammation.
Mind-Body Practices
Mind-body approaches such as yoga, tai chi, or meditation can ease stress and support the nervous system, which directly influences immunity. Pick something you enjoy, because the benefit comes from practice over time.
Detox and Environment
Supporting the immune system also means lowering unnecessary exposures. Keep your indoor air clean by controlling moisture and ventilation, choosing whole foods with fewer additives, and using safe water whenever possible.
Gut health matters here, too. Eating fiber-rich vegetables, fermented foods, and quality proteins helps protect the gut lining and lowers the risk of “leaky gut,” which can make the immune system more reactive.
Clinical Modalities
In some cases, people explore additional therapies with their healthcare provider:
- IV nutrient therapy to quickly restore nutrient levels
- Ozone autohemotherapy, which is still being studied for its immune effects
These work best when combined with strong nutrition and lifestyle foundations. At Lam Clinic, we offer IV nutrient therapy and ozone autohemotherapy in a supervised setting.
Our custom IV blends are designed to restore nutrients and energy, while ozone is used carefully when appropriate.
Remember: Your immune system is adaptable. With nourishing food, restorative sleep, stress skills, and thoughtful support, many people living with autoimmune disease discover more resilience and steadier energy over time.
