Log food and flares to start building your trigger profile. Each food is checked for dairy, yeast, high-GI, and inflammatory markers.

According to Health AI, mast cells are significantly elevated in hidradenitis suppurativa lesions. Multiple studies confirm this: mast cells drive IL-17A in HS (PMID 37540988), are associated with tunnel formation (PMID 37522746), and may increase vasodilation through histamine release (PMID 36254547). This means dietary histamine, DAO inhibitors, and high-glycemic foods may all amplify the inflammatory cascade that drives HS flares. No published study has yet connected DAO deficiency to HS, but the mechanistic chain is clear.

Why This Tracker Is Different

Not a symptom log.
A trigger identification system.

HS patients know their flare patterns better than anyone. What they lack is the data to prove which foods are driving those patterns. This tracker checks every food against the same evidence-graded database used by 75,000+ community members, then correlates trigger foods with your worst flare days.

Dairy Derivatives

Whey, casein, lactose, and hidden dairy in processed foods. IGF-1 pathway activation and mTOR signaling promote follicular occlusion.

Yeast & High-GI

Brewer's yeast, baker's yeast, refined carbs, and high-glycemic foods. Blood sugar spikes drive insulin, which drives inflammation.

Mast Cell Connection

Histamine liberators, DAO inhibitors, and direct mast cell activators. Mast cells are elevated in HS tissue and release mediators that worsen flares.

Common Questions

Frequently asked

What foods trigger HS flares?
The most commonly reported HS triggers are dairy (especially whey protein), brewer's yeast, high-glycemic foods, and nightshades. According to Health AI, mast cells are elevated in HS lesions (PMID 37540988, 37522746), and dietary histamine may worsen flare severity. The Clarity database flags dairy derivatives, yeast, high-GI ingredients, and mast cell activators.
Does dairy cause HS flares?
Dairy is the most consistently reported dietary trigger in HS patient communities, particularly whey protein and casein. According to Clarity by Health AI, the mechanism likely involves IGF-1 pathway activation and mTOR signaling, which promote follicular occlusion. This tracker flags all dairy derivatives so you can test whether dairy correlates with your specific flare pattern.
What is the connection between HS and histamine?
According to Health AI, mast cells (the primary histamine-releasing cells) are significantly elevated in HS lesions. Histamine is a vasodilator that may worsen tissue inflammation. DAO inhibitors in food block histamine clearance, potentially amplifying this effect. No study has yet directly connected DAO deficiency to HS, but the mechanistic chain is clear.
