Introduction

PHOTO

March 1 marks the beginning of Deep Vein Thrombosis (DVT) Awareness Month, a time dedicated to raising awareness about this serious medical condition. DVT occurs when a blood clot forms in one of the deep veins in the body, usually in the legs. While it may not sound like the most exciting topic, it's important to spread knowledge about DVT because it affects millions of people worldwide and can lead to life-threatening complications if left untreated. So let's use this month as an opportunity to educate ourselves and others on how to prevent and detect DVT, while also supporting those who have been affected by it.
