Raynaud’s Phenomenon Functional Medicine Care
Conditions We Support
Tired of cold hands and feet? We help manage Raynaud's Phenomenon by improving your circulation and immune health.
What is Raynaud's Phenomenon?
Raynaud's phenomenon is a condition that can occur on its own (known as primary Raynaud's), or it can be a sign of an underlying autoimmune disease (known as secondary Raynaud's). It is estimated to affect an average of 6.5% of people (8-10% of women and 3-5% of men). It is commonly associated with Sjögren's Syndrome.
Raynaud's affects the arteries and blood vessels, causing vascular ‘spasms’ that restrict blood flow to extremities such as the ears, toes, and nose. These spasms can be triggered by mild cold or even emotional distress.

Raynaud's Phenomenon Symptoms
Do you suspect or know that you have Raynaud's phenomenon? You may experience symptoms such as these:
- Sensitivity to cold in ears, toes, nipples, knees, or nose
- Fingers that turn pale or white then blue when exposed to cold, or during stress or emotional upset, then red when the hands are warmed
- Hands that may become swollen and painful when warmed
Triggers for Raynaud's Phenomenon
What can trigger or fuel Raynaud's phenomenon?
- Gluten sensitivity or other food triggers
- Viral infection such as Epstein Barr virus (EBV)
- Plastics like BPA, phthalates, parabens
- Small intestinal bacterial overgrowth
- Mold toxicity
- Low glutathione status
- Hormonal imbalances
- Nutrient deficiencies
- Leaky gut
- Blood sugar dysfunction
- Low vitamin D
When Raynaud’s Needs an Autoimmune Workup
Color-change episodes deserve a careful history; labs help sort primary patterns from secondary autoimmune links:
- ANA and related antibodies if secondary Raynaud’s is suspected
- Evaluation for associated conditions such as Sjögren’s, scleroderma, or lupus
- Circulation and symptom triggers (cold, stress)
- Gut and inflammatory markers when systemic autoimmune disease is possible
- Prior rheumatology notes when Raynaud’s appears with joint pain, dryness, or rashes
Primary vs Secondary Raynaud’s
Primary Raynaud’s occurs on its own. Secondary Raynaud’s can signal an underlying autoimmune disease and deserves a broader workup. Conventional care includes trigger avoidance, hand-warming strategies, and sometimes medication for severe cases.
Functional medicine looks for immune and vascular contributors, especially when Raynaud’s appears with fatigue, joint pain, dryness, or positive antibodies.
Mechanistically, episodic vasospasm reduces blood flow to fingers or toes in response to cold or stress. When autoantibodies or connective-tissue disease are present, the same symptom can be a clue rather than an isolated circulation quirk — which is why we take overlapping autoimmune features seriously.
Our Approach to Raynaud’s
We clarify primary vs secondary patterns, review autoimmune labs, and build a plan addressing inflammation, gut health, and lifestyle triggers while coordinating with specialists when connective-tissue disease is present.
What testing looks like: ANA and related antibodies when secondary disease is possible, review for Sjögren’s, lupus, or scleroderma features, and gut or inflammatory markers when the systemic picture suggests more than cold hands alone.
What to expect: telehealth history and trigger mapping from Boulder, practical lifestyle strategies, and clear escalation guidance — digital ulcers, severe asymmetric attacks, or new systemic symptoms need prompt in-person evaluation.
How Can Dr. Autoimmune Help?
It can be frustrating trying to find help with chronic and complex conditions, which is why we have chosen to dedicate our practice to exactly that. Instead of treating the symptoms, the functional medicine approach focuses on uncovering the causes.
All autoimmune diseases start in the gut. We design custom plans of dietary intervention, supplements and lifestyle recommendations to help heal the gut and support the immune system. In supporting these fundamental functions of the digestive tract we can reduce inflammation and see dramatic changes in symptoms.

Finding the Root Cause
We know that autoimmunity requires 3 things to develop:
- 1Genetic predisposition
- 2Leaky gut (a.k.a intestinal permeability)
- 3An environmental trigger
It All Starts in the Gut!
Our small intestine consists of 25 feet of tubing, the inside surface area being equivalent to that of a doubles tennis court!
Proteins called “tight junctions” prevent a flood of material into the gut. Low vitamin D levels coupled with inflammation in the gut starts to widen the space between cells, allowing materials (bacteria and food) to start seeping through. This triggers inflammation and antibodies are formed against your own tissue.

Frequently Asked Questions
New Raynaud’s in adulthood, asymmetric findings, digital ulcers, or accompanying systemic symptoms (rash, joint pain, dryness, abnormal antibodies) warrant a broader autoimmune evaluation with your clinician.
