Autoimmune & Inflammatory Conditions
Your immune system is supposed to protect you. In autoimmune conditions, it turns on your own tissue instead — attacking joints, thyroid, intestinal lining, nerves, skin, connective tissue, and more. These conditions are common, frequently misdiagnosed, and almost always undertreated. Every page in this section is built around plain language, real sources, and honest information about what is known, what isn't, and what you can actually do about it.
I'm not a doctor. I'm not telling you to change your medication. Everything in this library is personal testimony and links to real medical sources. Always work with a qualified physician. Always ask for the right test by name.
Celiac Disease
An autoimmune condition triggered by grain proteins — not just gluten, but an entire family of proteins that the human digestive system cannot fully break down. Every exposure causes immune-mediated damage to the small intestinal lining. The damage is cumulative, the symptoms span almost every system in the body, and the average time from first symptoms to correct diagnosis is 6 to 10 years. The only treatment is complete, permanent grain elimination.
Gluten Intolerance / Non-Celiac Gluten Sensitivity
Real, miserable, and frequently confused with celiac disease — but a different condition with a different mechanism. No autoimmune marker. No intestinal damage visible on biopsy. Still produces significant GI and systemic symptoms in response to grain exposure. The distinction matters because the testing, the diagnostic pathway, and the clinical implications are not the same. This page covers the hard line between the two.
Hashimoto's Thyroiditis
The most common cause of hypothyroidism in the developed world, and one of the most under-diagnosed autoimmune conditions in existence. The immune system attacks the thyroid gland, gradually destroying its ability to produce the hormones that regulate metabolism, energy, mood, temperature, and more. Many people with Hashimoto's are told their thyroid levels are "normal" for years while their symptoms worsen. Knowing what to ask for changes the conversation.
Graves' Disease
Where Hashimoto's slows the thyroid down, Graves' disease drives it into overdrive. The immune system produces antibodies that stimulate the thyroid to produce excess hormone — resulting in a body running too hot, too fast, for too long. Heart palpitations, weight loss, anxiety, tremor, heat intolerance, and in some cases significant eye involvement. Frequently misattributed to anxiety or stress before the thyroid connection is made.
Rheumatoid Arthritis
Not the same as the wear-and-tear arthritis that comes with aging. Rheumatoid arthritis is an autoimmune condition in which the immune system attacks the synovial lining of the joints — causing inflammation, pain, swelling, and over time, permanent structural joint damage. It is systemic, meaning it affects the whole body, not just the joints. Early intervention matters because the window for preventing irreversible damage is real and finite.
Lupus
One of the most complex and variable autoimmune conditions known to medicine. Lupus can attack almost any organ system — joints, skin, kidneys, heart, lungs, brain, blood vessels. It flares and remits unpredictably. It mimics dozens of other conditions. It disproportionately affects women and is significantly underdiagnosed in men. The butterfly rash across the cheeks and nose is the textbook presentation. Most people with lupus never have the textbook presentation.
Sjogren's Syndrome
An autoimmune condition that primarily targets the moisture-producing glands — resulting in severe dry eyes, dry mouth, and difficulty swallowing. Frequently dismissed as a minor inconvenience. It is not. Sjogren's has systemic reach that includes fatigue, joint pain, neurological involvement, and significantly elevated risk of lymphoma. It is also one of the most commonly missed diagnoses in rheumatology — often running for years before anyone names it.
Multiple Sclerosis
The immune system attacks the myelin sheath — the protective coating around nerve fibers in the brain and spinal cord. As the myelin is damaged, nerve signals slow, misfire, or stop transmitting entirely. The result is a wide range of neurological symptoms that vary dramatically depending on which nerves are affected. MS presents differently in almost every person who has it, which is a significant part of why it takes an average of several years to diagnose.
Psoriasis / Psoriatic Arthritis
Psoriasis is an autoimmune condition that accelerates the skin cell cycle — producing thick, scaly plaques on the skin surface. It is chronic, it flares, and it is about far more than appearance. Roughly 30% of people with psoriasis develop psoriatic arthritis — joint inflammation that can cause permanent damage if untreated. Both conditions are driven by the same underlying immune dysregulation and both respond to similar interventions. The skin and the joints are connected. This page covers both.
Myositis
An autoimmune condition in which the immune system attacks muscle tissue directly — causing progressive muscle weakness, inflammation, and pain. The presentation varies depending on which muscles are most affected, but commonly includes difficulty climbing stairs, lifting arms overhead, swallowing, and eventually breathing. Myositis is rare enough that many physicians have limited clinical experience with it, which contributes to significant diagnostic delays.
Inclusion Body Myositis
A specific and particularly difficult form of myositis that deserves its own page. Inclusion body myositis tends to present later in life, progresses slowly but relentlessly, and does not respond to the immunosuppressive treatments that help other forms of myositis. It is the most common inflammatory muscle disease in people over 50 and is almost universally misdiagnosed — most often as polymyositis or as general age-related weakness — for years before anyone gets it right.
Endometriosis
Tissue similar to the uterine lining grows outside the uterus — on ovaries, fallopian tubes, bladder, bowel, and in severe cases beyond the pelvic cavity entirely. It bleeds with each menstrual cycle, with nowhere to go. The result is inflammation, scarring, adhesions, and pain that can be severe enough to be debilitating. Endometriosis affects an estimated 1 in 10 women of reproductive age. The average time from first symptoms to diagnosis is 7 to 10 years. It is not "bad periods." It is a systemic inflammatory disease that deserves to be taken seriously.
Mast Cell Activation Syndrome (MCAS)
Mast cells are immune cells that release histamine and other inflammatory compounds in response to triggers. In MCAS, they fire inappropriately and excessively — producing a wide range of symptoms across multiple organ systems including flushing, hives, GI distress, brain fog, heart palpitations, and in severe cases anaphylaxis. The trigger list is long and highly individual — foods, medications, temperature changes, stress, fragrances, and more. MCAS is increasingly recognized as an underlying driver in conditions that don't respond to standard treatment, including some presentations of ME/CFS and long COVID.
