Mast Cell Activation Syndrome - MCAS

Common MCAS Symptoms

The symptoms of MCAS are diverse and can impact multiple systems, leading to a challenging diagnosis. Common symptoms include:

• Allergic Reactions: Itchy skin, hives, or rashes
• Digestive Issues: Nausea, vomiting, abdominal pain, acid reflux, diarrhea or constipation
• Respiratory Problems: Asthma, wheezing, or nasal congestion
• Neurological Symptoms: Headaches, dizziness, or brain fog, resistant anxiety or depression, neuropathy (abnormal nerve sensations)
• Cardiovascular Symptoms: Palpitations, low blood pressure, lightheadedness/dizziness or flushing

Toxic Mold and MCAS

Toxic mold exposure is a significant environmental factor that can trigger or exacerbate MCAS symptoms. Mold toxins, particularly mycotoxins, can activate mast cells, leading to an increase in histamine release and worsening MCAS symptoms. If you feel sick from mold exposure, it’s crucial to address both the mold exposure and the mast cell activation.

Environmental Toxins and MCAS

Environmental toxin exposure to pesticides, herbicides (eg. glyphosate/Round-up), insecticides, microplastics (parabens/phthalates), heavy metals, common additives to perfumes and colognes, skin products and many others can act as triggers to mast cell responses.

Infections and MCAS

Systemic infections that typically disguise themselves as low-grade and chronic in nature can trigger mast cell responses. These infections include viruses such as EBV/cytomegalovirus, bacterial such as Lyme (Borrelia), Bartonella, Anaplasma and other vector-borne infections, fungal pathogens such as Candida and aspergillus, and parasites such as Babesia are common problematic factors in triggering MCAS. Chronic exposure to GI-related pathogens such as Clostridia, E.coli, Giardia, Entamoeba, Klebsiella, Candida, etc. can cause mast cell responses.

Limbic System and MCAS

Unresolved trauma within implicit memory systems (sometimes subconscious) and other tendencies towards unregulated “threat” responses within the central nervous system are known aggravators of mast cell responses.

Ketosis/Autophagy Impairments

Failure to induce cellular states of ketosis prevents proper detoxification of the cell and failure to induce apoptosis (autophagy) fails to clean up and recycle dysfunctional cells; both can worsen mast cell responses.

Systemic histamine production/methylation issues masking as MCAS

Failure to methylate histamine and production of histamine through CCL5/HDC enzymatic pathways can appear as MCAS but actually are the result of systemic histamine production with failure to break down and remove histamine from the system.

Naturopathic Modalities for MCAS

A naturopathic approach to managing MCAS focuses on addressing the root causes and supporting the body’s natural healing processes. Here’s how:

1. Identifying and Managing Mold Toxicity

• Tests for Mold Toxicity: Begin with comprehensive testing to identify mold exposure and mold toxicity in your environment. Tests may include blood mycotoxin tests, mold allergy tests, and indoor air quality assessments.
• Environmental Remediation: Eliminate mold sources from your home or workspace and ensure proper ventilation and air purification to reduce exposure.

2. Mast Cell Mediator and Histamine Management

• Histamine Blockers: Medications or supplements that block histamine receptors can help reduce the symptoms associated with histamine release. These include H1 and H2 antihistamines, which work to counteract histamine’s effects on the body.
• Histamine Inhibitors: Certain supplements and dietary strategies can help inhibit histamine production. Vitamin C and quercetin are known for their antihistamine properties and can support overall mast cell stability.
• Other mast cell mediator therapies: Several medications and supplements can be considered to help reduce the release or activity of other mediators (chemicals) that mast cells can release to cause symptoms in this condition. This will be assessed in detail by your practitioner to determine best course of action

3. Dietary and Lifestyle Modifications

• Low-Histamine Diet: Implementing a low-histamine diet can be beneficial. This involves avoiding foods that are high in histamine or that trigger histamine release, such as aged cheeses, processed meats, and fermented foods.
• Anti-Inflammatory Foods: Incorporate anti-inflammatory foods into your diet to support overall health and reduce mast cell activation. Focus on fresh fruits, vegetables, omega-3 fatty acids, and herbal teas.

4. Stress Management

• Mind-Body Practices: Stress can exacerbate MCAS symptoms. Engaging in practices such as yoga, meditation, and deep breathing exercises can help manage stress levels and support mast cell health.

5. Supplements and Herbs

• Antihistamine Supplements: Supplements like bromelain, nettle, and ginger may provide additional support in managing histamine-related symptoms.
• Mast Cell Stabilizers: Certain herbal remedies and supplements can help stabilize mast cells and reduce their overactivity.

Working with a Naturopathic Doctor

A naturopathic doctor can provide personalized protocols tailored to your specific needs and symptoms. They will help you navigate the complex interplay between mold exposure and MCAS, and help you understand the optimal approaches for your specific case, ensuring that both environmental and physiological factors are addressed for optimal health.

If you suspect you have MCAS or are experiencing symptoms related to mold exposure, consider consulting with a naturopathic doctor to explore comprehensive, integrative and natural treatment options. By focusing on the underlying causes and supporting your body’s healing processes, you can work towards managing your symptoms effectively and improving your overall quality of life.
