Deep vein thrombosis or DVT is a condition which forms blood clots in deep veins due to the improper mixture of plasma and platelets. This cuts off the supply of deoxygenated blood from the affected vein to the heart. Anybody can get a DVT, but certain factors increase one’s risk of developing it. Let’s take a look at the risk factors and diagnosis methods of DVT.

Risk factors
Anything that interferes with the blood flow of the body can cause DVT. Here are a few of the factors that increase one’s risk.

1. Inactivity
Being immobile for long periods, being on complete bed rest, and lacking exercise can cause blood clots. Everyday things like sitting for too long on a chair while working, watching movies, or playing videos can also cause clots.

2. Birth control
Women who take combination pills containing estrogen and progestin have a higher chance of developing a clot. Nevertheless, the risk is lower than that of pregnant women. Birth control methods such as vaginal rings and patches may also pose a risk of clots.

3. Genes and family history
Genetic disorders such as thrombophilias cause gene mutations which in turn increase the risk of blood clots. Additionally, if one’s parents or siblings suffer from the condition, they are most likely to suffer from it too.

4. Obesity
The extra weight in the body adds more pressure on one’s veins and thus interferes with the body’s blood flow. Moreover, obesity causes the heart to work harder, which may impair the functionality of the heart. All of this can increase one’s risk of developing DVT.

5. Childbirth
Women who are pregnant or have recently given birth are at a greater risk of developing DVT. This happens due to the changes in hormonal levels and the baby’s pressure put on the mother’s blood vessels during childbirth. Staying hydrated, being active, and managing weight can decrease the risk of blood clots.

Diagnosis
The different diagnosis methods used for DVT are as follows:

1. Venography
In this test, a dye is inserted into a vein in the leg followed by an X-Ray that helps create an image of the legs and thus, look for clots. This test may be harmful; therefore, it is rarely recommended.

2. MRI
Magnetic resonance imaging uses magnetic waves to obtain clear images of the internal organs of the body. A doctor may recommend an MRI to check for DVT veins in the abdomen when it comes to DVT.

3. Duplex ultrasound
The duplex ultrasound is the standard test for clot-related problems. This imaging test uses sound waves to check for any clots or blockages in the veins. Sometimes, a doctor may recommend a series of ultrasounds to check for any progress or changes related to the clot.

4. D-dimer blood test
The D-Dimer blood test helps rule out Pulmonary embolism. This test helps a doctor understand the levels of a protein called D-dimer produced by blood clots. When a person has blood clots, their D-dimer levels increase significantly.
