Deep Vein Thrombosis (DVT): What You Need to Know

Deep vein thrombosis, or DVT, is a blood clot that forms in a deep vein, usually in the leg. It can feel like a muscle cramp, a heavy ache, or a sudden swelling. If the clot breaks loose, it can travel to the lungs and cause a serious condition called pulmonary embolism. Knowing the signs and how to lower your risk can save a life.

Common Signs You Shouldn't Ignore

Most people notice at least one of these symptoms:

• Swelling in the calf or thigh that comes on quickly.
• Warmth or a hot feeling in the affected area.
• Pain or cramp that feels worse when you stand or walk.
• Red or discolored skin over the clot.

If you get any of these, especially after a long flight, surgery, or a period of immobility, call your doctor right away. Early treatment often means a simple blood‑thinner pill or a short stay in the hospital.

Easy Ways to Lower Your DVT Risk

Most DVT cases can be avoided with a few everyday habits:

1. Keep moving. On long trips, stand up and walk every hour. At home, do ankle circles or short walks if you're sitting for long periods.
2. Stay hydrated. Drinking water helps keep your blood from getting too thick. Aim for at least eight glasses a day, more if you're active.
3. Wear compression socks. They gently squeeze the legs and improve blood flow, especially after surgery or during travel.
4. Maintain a healthy weight. Extra weight puts more pressure on your veins and can increase clot risk.
5. Talk to your doctor about medication. If you have a history of clots, heart disease, or are on hormone therapy, you might need a preventive prescription.

Simple changes add up. Even short stretches before bed or a quick walk around the office can keep blood moving.

Remember, DVT isn’t something that only older people get. Athletes, pregnant women, and anyone on a long plane can develop a clot. The key is to stay aware of the symptoms and act fast. If you think you have a clot, don’t wait—get medical help. Early treatment is usually straightforward and can prevent a life‑threatening emergency.

By knowing what DVT looks like and taking a few practical steps each day, you can protect yourself and your loved ones from this hidden danger.
