Deep vein thrombosis (DVT) is one of the more common diseases that can affect anyone. Blood clot formation in the deep veins can result in DVT, which, if unresolved, may lead to pulmonary embolism. Pulmonary embolism is a condition where the blood clots may travel along with the blood and get deposited in the lungs causing serious issues. Reported as muscle cramps or leg pain, DVT can have serious effects if left untreated. Symptoms manifest as sudden cramps mostly in the lower limbs while running, swimming, or doing vigorous exercises.

However, DVT can occur anywhere in the body. To understand the treatments and diagnosis, one should be well informed about the causes of deep vein thrombosis. This will also help in preventing it to a great extent. A number of health conditions can be major causes of deep vein thrombosis. The diagnosis and treatment of DVT solely depend on the cause of the condition. Thus, this article presents some of the causes of deep vein thrombosis:

1. Injury to the vein
Internal damage to the vein may be one of the most common causes of deep vein thrombosis. It may occur due to any accidental damage, fracture to the attached or proximal bone, etc.

2. Surgery
In some cases, surgeries can also have an adverse effect on the body, causing deep vein thrombosis. It is mostly in the case of major surgical operations that involve deep sutures and recovery. Surgeries of the lower abdomen, or lower part of the body including the pelvis, lower limbs, hips, etc., can be causes of deep vein thrombosis.

3. Chronic respiratory system diseases
One of the prime causes of deep vein thrombosis is the anomalous condition of the respiratory system. It can be any kind of heart disease or diseases that affect the lungs or blood regulation. Apart from this, certain serious and chronic bowel (inflammatory) ailments can also result in deep vein thrombosis.

4. Cancer
There are some types of cancer that affect the deep-seated veins in the body leaving higher risks of deep vein thrombosis later on. Apart from that, prolonged or intense radiation, chemotherapy, or other treatments for cancer may also be major causes of deep vein thrombosis.

5. Faulty blood clotting
This is one of the common causes of deep vein thrombosis, and it may require prolonged treatment. In a few rare cases, the patient may need a blood transfusion to replace the faulty clotting factor.

6. Other health conditions
Apart from the above-listed causes, there are many other risk factors. For example, any rise or surge in the Basal Metabolic Index or the Basal Metabolic Rate can make the body more prone to deep vein thrombosis. This is more common in individuals who are overweight, which is why doctors may primarily suggest weight loss procedures. Besides, people who have chronic health conditions that affect major organs in the body may also be prone to DVT.
