Bullous Pemphigoid: When Your Immune System Attacks Your Skin

When Blisters Signal a Deeper Immune Problem

Bullous pemphigoid is an autoimmune blistering disorder where the immune system produces antibodies that attack proteins in the skin's basement membrane. Large, fluid-filled blisters form on the skin surface, most commonly on the limbs and trunk. It primarily affects people over 60.

Why the Immune System Attacks the Skin

Autoantibodies target BP180 and BP230 — proteins that anchor the epidermis to the dermis. Known precipitants include certain medications (furosemide, ACE inhibitors), ultraviolet light exposure, neurological conditions (Parkinson's disease, multiple sclerosis), and burns or trauma to the skin.

The Autoimmune Connection

Functional medicine examines the upstream drivers: gut permeability ("leaky gut") allows bacterial antigens to activate systemic immune responses; vitamin D deficiency — a key immune regulator, consistently low in autoimmune patients; omega-3 deficiency; and chronic infections that can trigger or sustain autoimmune activity.

FXMed's Immune Support Approach

Dermatology manages the blisters; functional medicine addresses why the immune system is misfiring. Our Immune Support Programme tests vitamin D, gut microbiome, inflammatory markers, and omega-3 index, then delivers a targeted protocol to modulate immune activity and reduce flare frequency.
