Patient's Query

Hi doctor,

I am a 37-year-old male with factor V clotting disorder. How can I prevent blood clots?

Kindly suggest.

Hello,

Welcome to icliniq.com.

Most people with factor V Leiden never have any symptoms. But some are at a higher risk of getting blood clots, especially in the legs or the lungs. When clots do occur, they can cause warmth, redness, pain, and swelling in the leg.

These are symptoms of a condition called deep vein thrombosis. It is a blood clot in a vein deep in the leg. Breathing problems, sharp chest pain, coughing, and a fast heartbeat are the symptoms of a condition called pulmonary embolism. It is a blood clot in the lungs. It usually comes from a blood clot in the leg that breaks off and travels to the lungs.

I suggest you follow:

  1. To prevent this, the best thing you can do is move your legs often. This keeps the blood moving. Not moving for an extended period of time can increase your risk of clots. Examples are having surgery, being stuck in bed, or taking a long trip.
  2. To prevent a clot on travel, you can stand up and walk around every hour or two (or if driving, take breaks often).
  3. You should wear loose, comfortable clothes, often change your sitting position and move your legs and feet often, drink plenty of fluids, and wear knee-high compression stockings, especially if you get leg swelling.

I hope that this answers your query.

Kindly follow up if you have more doubts.

Thank you.
