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

Deep vein thrombosis, or DVT, is a blood clot that forms in the deep veins of your legs or thighs. It can feel like a sore muscle, but it’s more serious because the clot can break loose and travel to your lungs, causing a pulmonary embolism. Knowing the warning signs and how to stop it from getting worse can save lives.

Common Signs and When to Seek Help

If you notice sudden swelling in one leg, a warm feeling, or a red, tight skin stretch, don’t ignore it. Pain that gets worse when you stand or walk is another clue. These symptoms often appear in the calf or thigh and may feel like a cramp. If any of these signs show up, call your doctor right away—early treatment is easier and safer.

People who sit for long periods, travel on long flights, or have recent surgery are more likely to develop DVT. Other risk factors include obesity, smoking, cancer treatment, and certain genetic clotting disorders. Even a family history of clots can raise your chances. Knowing your personal risk helps you stay alert.

Preventing and Treating DVT

The first step in prevention is moving around. If you’re on a long flight or car ride, get up every hour to stretch and walk a few steps. Simple leg exercises—like flexing your ankle up and down—keep blood flowing. Compression stockings also help by gently squeezing the leg to improve circulation.

If a clot is found, doctors usually prescribe blood thinners (anticoagulants). These medicines don’t dissolve the clot right away but stop it from growing and give your body time to break it down. In some cases, a short‑term clot‑busting drug (thrombolytic) may be used, especially if the clot is large or causing severe symptoms.

Follow‑up appointments are key. Your doctor will check blood tests to make sure the medication is working and adjust the dose if needed. Most people stay on blood thinners for three to six months, but some high‑risk patients need longer treatment.

Beyond medication, lifestyle changes support recovery. Stay active, keep a healthy weight, and quit smoking. Eating a balanced diet rich in fruits, vegetables, and whole grains can improve overall blood health. If you have a known clotting disorder, your doctor may suggest a long‑term plan that includes periodic check‑ups and possibly lower‑dose anticoagulants.

Bottom line: DVT is a serious condition, but it’s also preventable and treatable. Spotting the signs early, moving regularly, and following medical advice give you the best chance to stay clot‑free and healthy.
