Thrombosis is a health condition in which blood clots form inside the blood vessels and block blood flow. Thrombosis can develop due to a variety of reasons and knowing your risk factor can aid with preventative care.

Risk factors for Thrombosis

Thrombosis occurs when the inner lining of the blood vessel is damaged, resulting in a slowing of blood flow and an increased probability of clot formation. Many health conditions, as well as lifestyle factors, are risk factors for the development of thrombosis. Almost anyone can suffer from thrombosis, but certain circumstances can increase the chances of thrombosis. Some risk factors of thrombosis are:

  • Atherosclerosis, the build-up of sticky substances (plaque) in the arteries.
  • Obesity
  • High cholesterol
  • High blood pressure
  • Autoimmune diseases like antiphospholipid syndrome, systemic lupus erythematosus, rheumatoid arthritis, inflammatory bowel disease, multiple sclerosis, etc.
  • Blood clotting disorders
  • Atrial fibrillation
  • Cancer
  • Chemotherapy
  • Diabetes
  • Family history of blood clot diseases
  • Surgeries like the placement of a central line or surgery of the hip, pelvis, or legs
  • Fractures
  • Severe muscle injury
  • Stroke
  • Paralysis of the leg
  • Prior heart attack
  • Heart valve disease
  • Sitting without moving legs for long hours of flight, car travel, or bed rest
  • Pregnancy
  • Birth control pills containing oestrogen
  • Hormone replacement therapy for menopause
  • Older age
  • Smoking
  • Poor diet

The presence of two to three risk factors in a person can drastically increase the chances of thrombosis. Typical symptoms of thrombosis include sudden pain, redness, swelling in limbs, fever, difficulty breathing, pain in the chest, rapid heartbeat, sudden weakness on one side, and an altered mental state.

Conclusion

Thrombosis can have severe health complications. Several risk factors exist, including autoimmune disease and a family history of blood clotting. It may be wise to purchase comprehensive health insurance to cover the costs associated with this critical illness. If you or a loved one carry any risk factors of thrombosis, it may be beneficial to consult a healthcare provider.
