Could It Be a Blood Clot?

This isn't a diagnosis — it's awareness. Answer a few questions and know when to act. Early action saves lives.

Three steps.
60 seconds.
Could save your life.

Blood clots are often misdiagnosed or ignored. The symptoms can feel like a pulled muscle, tiredness, or normal aging. Chris Gere's legs hurt at a cross country meet — he almost didn't go to the ER. He did. It saved his life.

Founder Story

Built By a Survivor.

ClotNation isn't a startup idea. It's a response to a life-or-death moment — and a commitment that others won't face it alone.

"Don't let clots take you in your prime. That's not just a lyric — it's the reason ClotNation exists."

In 2021, Chris Gere was helping at his son's cross country meet when his legs started hurting. He almost wrote it off as getting older. He didn't.

After a 12-hour emergency room wait, scans revealed DVT — deep vein thrombosis — and a pulmonary embolism in his lungs. Both conditions. At the same time. Either one could have been fatal.

He was later diagnosed with Factor V Leiden, a genetic clotting disorder affecting roughly 1 in 20 people. He now takes blood thinners every night. And he turned his experience into a song, a movement, and ClotNation — the platform he wished had existed when it happened to him.

The ClotNation Anthem

The Song That Started It All.

Before there was an app, there was a song. Chris wrote "Blood Clot Story" to tell his truth — and turn it into awareness for everyone.

Written and performed by Chris Gere

Anybody can get a blood clot — trust me, this happens a lot.
Twice as many deaths as from gunshots — hundred thousand each year, that's a lot.
Protect your family and learn the signs — at stoptheclot.org online.
They hit me with that blood thinner — now I take my meds every night, so grateful, yeah. It keeps me right.
Don't let clots take you in your prime.

Know What You're Facing.

Most people have never heard of DVT, PE, or Factor V Leiden — until it happens to them. ClotNation changes that.

What is DVT?
Deep Vein Thrombosis
DVT is a blood clot that forms in a deep vein, usually in the legs. It can cause swelling, pain, and warmth — or no symptoms at all. Without treatment, the clot can break loose and travel to the lungs.

What is PE?
Pulmonary Embolism
A PE happens when a clot breaks free and blocks blood flow to the lungs. It is life-threatening and requires emergency care. Sudden shortness of breath, chest pain, and rapid heartbeat are warning signs. Chris survived both DVT and PE simultaneously.

Factor V Leiden
Genetic Clotting Disorder
Factor V Leiden is the most common inherited clotting mutation. It makes your blood more prone to clotting. Up to 5% of people carry it — most are never tested until after a clot event. A simple blood test can detect it.

Prevention
What You Can Do Today
Many clots are preventable. Move regularly on long flights and drives. Stay hydrated. Wear compression socks. Know your family history. If you've had surgery or a recent clot, talk to your doctor about blood thinners and monitoring.
Stay Active Hydrate Compression

Warning Signs
Know When to Act Fast
Don't ignore: unexplained leg or arm swelling, calf pain when walking, sudden shortness of breath, chest pain, a rapid heartbeat, or a severe headache. These symptoms together — especially after travel or surgery — require immediate medical attention.
