Histamine Intolerance & Mast Cell Activation Screener

🍷 Histamine Intolerance & Mast Cell Activation Screener

Determine whether post-meal flushing, sudden nasal congestion, hives, or heart racing stem from DAO enzyme breakdown deficits or systemic mast cell reactivity.

1. Post-Meal Physical Triggers:

No noticeable reactions to aged cheeses, wine, fermented foods, or leftovers

Symptoms appear primarily after consuming high-histamine foods (wine, aged cheese, tomatoes, spinach, leftovers)

Reactions are unpredictable—triggered by foods, temperature shifts, stress, odors, or medications

2. Skin & Facial Flushing Symptoms:

Normal skin reactivity; no unprovoked redness or hives

Facial flushing, mild itching, or heat sensations within 1–2 hours after eating

Frequent dermatographism (skin writing), sudden hives, severe flushing, or swelling (angioedema)

3. Head, Respiratory & Cardiovascular Signs:

Clear sinuses and steady heart rate following meals

Runny nose, sinus congestion, or mild "histamine headaches" shortly after eating

Heart racing (tachycardia), sudden blood pressure drops, wheezing, or brain fog across multiple systems

4. Gastrointestinal Motility & Reactivity:

Comfortable digestion without rapid bloating or stomach cramping

Localized gut distress: sudden loose stools, abdominal cramping, or gas after histamine-heavy meals

Severe gut hyper-reactivity: alternating diarrhea/constipation, burning sensations, nausea, or food phobia
