Question

What specific conditions increase the risk for DVT in each category?

a) Physical activity, hydration, age
b) Smoking, diet, genetics
c) Surgery, pregnancy, immobility
d) All of the above

Answer 1

Conditions such as lack of physical activity, smoking, recent surgery, and predisposing health issues like heart failure can increase the risk for deep vein thrombosis (DVT). Preventative actions include movement and exercise to improve blood flow.

Step-by-step explanation:

Conditions that increase the risk for deep vein thrombosis (DVT) include:

• Lack of physical activity, dehydration, and advanced age can lead to poor circulation, increasing the risk for DVT.
• Smoking, an unhealthy diet, and genetics can contribute to blood vessel damage and altered blood composition, posing a higher DVT risk.
• Recent surgery, pregnancy, and prolonged immobility, as seen in long flights, can decrease blood flow in the veins, leading to clot formation.
• In general, a combination of the above factors, such as being immobile on a long flight with an underlying condition like heart failure, can significantly raise DVT risk.

Heart failure increases DVT risk by compromising the heart's ability to pump blood, leading to pooling and clot formation in the veins. Venoconstriction, or narrowing of the veins, can increase blood pressure within the vein, increase blood flow and aid in the return of blood to the heart. Regular movement and exercise help maintain regular blood flow, reducing DVT risk.
