Every July 23, the global health community pauses for one of the most overlooked autoimmune diseases in medicine — Sjögren's syndrome. It's been observed since 2010, marking the birthday of the Swedish ophthalmologist who first described it. This year's focus isn't a single slogan but a pledge: wear blue, tell someone, share a story, support research.

Sjögren's syndrome develops when the immune system turns on the body's own moisture-producing glands — mainly the ones responsible for tears and saliva. The result is dryness that can range from mildly irritating to genuinely disabling: eyes that burn like sand, a mouth too dry to speak comfortably through a meal. But the disease rarely stops there.

SYSTEMS SJÖGREN'S CAN INVOLVE BEYOND THE MOISTURE GLANDS

01 — WHY IT MATTERSThe long road to diagnosis

There's no single test for Sjögren's. Diagnosis usually depends on piecing together bloodwork, clinical exams, and sometimes a lip biopsy — a process that can take years, largely because early signs like fatigue or dry eyes are easy to dismiss as ordinary tiredness or seasonal irritation. Roughly four million people in the U.S. live with the condition, around nine in ten of them women, most diagnosed between ages 40 and 60. Every year this day exists to close that gap between the first symptom and the first real answer.

03 — LIVING WITH ITHow it's managed day to day

There's no cure yet, but Sjögren's is very manageable with the right combination of care. Treatment is built around the specific dryness and discomfort each person experiences, rather than one blanket approach.

Several disease-modifying and biologic therapies are also moving through clinical trials, aiming at the underlying immune activity rather than just its symptoms — encouraging progress for a condition that has long lacked targeted treatment.
