Veins carry blood with low oxygen to the heart for reoxygenation. While veins are found throughout our body, deep veins are located deep inside. We have seven such major deep veins in our bodies. If a blood clot or thrombus forms in a deep vein, it is called Deep Vein Thrombosis (DVT). It mostly affects deep veins in our arms and legs. If you do not treat it immediately, DVT can lead to serious complications.

Given below are the complications that arise due to DVT and tips to prevent them.

1. Pulmonary embolism
One of the most common complications from DVT is pulmonary embolism. The blood clot from the deep vein can break away and move into the bloodstream. As it travels, it can partly or completely block an artery. Pulmonary embolism can happen immediately after a thrombus or blood clot forms in the deep vein. It can also break away later.

2. Chronic venous insufficiency
If the clot in the deep vein stays in the hands or legs for a long time, it may damage the vein or the valves. When the valves do not function properly, it causes the blood to flow away from the heart instead of towards it.

3. Post-thrombotic syndrome
Another complication of DVT is post-thrombotic syndrome. This complication is a long-term condition with pain, swelling, and redness of the legs or arms. If you are not diagnosed and treated early, it can lead to sores and ulcers.

Steps to prevent DVT
If you are at risk for blood clots or DVT, you have to follow these steps diligently to avoid and prevent them:

1. Lose weight
If you are overweight, focus on losing weight. Instead of going in for crash diet programs, practice a combination of a good diet and an active physical lifestyle that can help you maintain your ideal weight for a longer time.

2. Walk
Walking is the simplest and most effective way to improve blood circulation. Make it a habit to walk for about 30 minutes every day to prevent DVT.

3. Be physically active
Even after you have reached your ideal weight, be physically active, especially if you are sitting for long hours at work.

4. Take breaks
If you are working behind a desk for many hours without a break, develop a habit of walking within your office or the coffee area. If you are driving, take a break every two hours, get out of the car, and stretch and move your limbs. During a flight, walk in the aisle every four hours.

5. Exercise
Even if you cannot move, learn toe and heel exercises that you can do in a sitting position.

6. Wear compression socks
Consult with your doctor about medication as well as compression socks if you are at risk of a blood clot. Compression socks are helpful to improve blood circulation and reduce the risk of blood clots.
