Deep vein thrombosis is a medical condition that causes a blood clot or thrombus in the deep veins. It mostly affects the leg and causes mild to severe pain and discomfort. It can also lead to complications if the clots loosen up and travel through the bloodstream. If a clot reaches the lungs, it can block blood flow and lead to pulmonary embolism. A venogram—an x-ray of the vein—may be performed for diagnosis.

1. Early warning symptoms of deep vein thrombosis
The symptoms and their intensity can vary depending on the stage, and they also differ from one patient to another. While some patients may experience a variety of symptoms, others might just experience a few of them. Let’s look at some of the early warning symptoms of deep vein thrombosis:

• Swollen veins
  The veins swell up in people with Deep Vein Thrombosis (DVT). Eventually, the veins become hard and sore to touch, causing intense discomfort.
• Redness
  The affected area reddens as a result of this condition. The skin might become itchy, and the area surrounding the affected vein also turns red in some cases, aggravating the discomfort associated with the condition.
• Cramps
  Leg cramps, as well as cramps in the calf muscle, are common early warning symptoms of DVT. These cramps are painful, and they are followed by pain, which leads to an uneasy feeling.
• Discoloration of the skin
  This condition causes discoloration of the skin in the affected area, and the surrounding area may also become discolored.
• Foot pain
  DVT mostly affects the legs, so pain in the legs is a telltale sign of the condition. Patients experience severe pain in the leg when they bend their feet, which can cause difficulty walking or even standing up at times.
• Warmth in the affected area
  A feeling of warmth in the affected area and the surrounding area commonly occurs in people with this disease.

2. Prevention of Deep Vein Thrombosis (DVT)
This disease can be prevented or managed effectively by following some simple lifestyle tips:

• Lose the excess weight
  Overweight or obese people should lose the excess pounds to relieve the pressure on the body and lead a healthy lifestyle.
• Avoid immobility
  People who have been on bed rest or have been leading a sedentary life should try to incorporate some physical activity in their daily routine. This can include simple things like getting up to take a short walk every once in a while when working at the office.
• Post-surgery care
  One should take proper care after surgery and follow the doctor’s instructions to prevent further complications. Also, one should take the prescribed medicines on time.
• Elevation of the legs
  Legs should be elevated while in bed, especially if one is going to sit for long.
