Autoimmune Disease Treatment in NYC
Conditions where the immune system attacks the body's own tissue — including lupus — are known worldwide for being difficult to diagnose and manage through conventional medicine alone.
Told to manage symptoms, but no one asks what’s driving them?
- Your diagnosis came with a prescription and not much else
- Flares come and go and you can’t predict them
- You want to understand the gut, thyroid and immune links
You’re not alone. Many of Dr. Kellman’s patients arrive after years of unexplained symptoms and being told their labs look normal. His job is to keep looking.
Beyond symptom management
Conventional treatment for autoimmune conditions like lupus often focuses on managing flare-ups rather than addressing what's driving the immune dysfunction in the first place.
Dr. Kellman's microbiome-centered approach has been shown to offer patients significant improvement — and in some cases, substantial reversal of symptoms — by addressing the gut-immune connection directly.
How we approach it
What is autoimmune disease?
In autoimmune disease, the immune system mistakenly attacks the body's own tissues. There are more than 80 autoimmune conditions, and together they are among the most common chronic illnesses. They are more common in women.
Conditions Dr. Kellman commonly sees include Hashimoto's thyroiditis, lupus, rheumatoid arthritis, celiac disease, psoriasis and inflammatory bowel disease.
Common symptoms
- Fatigue
- Joint pain, stiffness or swelling
- Skin rashes
- Low-grade fevers
- Digestive problems
- Hair loss
- Brain fog
Symptoms often come and go in flares, and they vary widely depending on which tissues are affected.
What drives autoimmunity?
Autoimmune disease usually develops from a combination of genetic risk and triggers. Factors studied include infections, the gut barrier and microbiome, chronic stress, hormones, smoking and nutrient status such as vitamin D. There is rarely a single cause.
A large share of the immune system sits in and around the gut, which is why Dr. Kellman's approach looks closely at the gut barrier and the microbiome.
How Dr. Kellman evaluates autoimmune conditions
Evaluation may include antibody tests specific to your condition (such as TPO, ANA, rheumatoid factor or anti-CCP), inflammatory markers, thyroid testing, vitamin D and other nutrients, and gut and microbiome testing. Care runs alongside your rheumatologist or other specialists.
Common questions
What causes autoimmune disease to develop?
Autoimmunity reflects a loss of immune regulation. Because a large share of immune tissue surrounds the gut, Dr. Kellman assesses microbiome disruption, intestinal permeability, infection, and toxic burden as contributors.
Does this replace my rheumatologist?
No. Dr. Kellman practices integrative medicine — conventional and functional together. Medication decisions stay with the treating specialist.
Do I need to stop my current autoimmune medication?
No. Dr. Kellman's care runs alongside conventional treatment. Never stop or change a prescribed medication without talking to the doctor who prescribed it.
Which autoimmune conditions does Dr. Kellman see?
Common ones include Hashimoto's thyroiditis, lupus, rheumatoid arthritis, celiac disease and inflammatory bowel disease, among others.
