Did your allergies, itching, swelling, or random flare-ups start after COVID?
You’re not alone — and it may be Post-COVID MCAS.
At MDPC Healthcare, we are seeing more patients with new or worsening symptoms after COVID infection, and many of them fit the pattern of Mast Cell Activation Syndrome (MCAS). Trust me we believe our patients! I’m an MCAS patient myself ❣️
⸻
🔬 What is Post-COVID MCAS?
MCAS happens when your body’s mast cells (immune cells that release histamine) become overly reactive.
Instead of responding only to true threats, they start firing from things that never used to bother you.
COVID can trigger lingering inflammation that keeps mast cells stuck in “high alert mode.”
⸻
✨ Common Symptoms We’re Seeing
• Itching or burning skin
• Eye or lip swelling
• Hives or flushing
• Headaches or migraines
• Bloating, nausea, diarrhea
• Fatigue
• Sensitivity to medications, fragrances, or foods
If your body suddenly feels “reactive,” this could be why.
⸻
🦠 Why COVID Triggers It
COVID causes a significant immune response.
For some patients, it leads to:
• Immune dysregulation
• Persistent inflammation
• Elevated histamine
• Over-activation of mast cells
These reactions can continue weeks to months even years after infection.
⸻
💛 You’re Not Imagining It
Post-COVID MCAS is real, and it can be confusing, uncomfortable, and disruptive.
The good news? It is manageable with the right plan.
⸻
🩺 How MDPC Healthcare Can Help
