There might be no apparent reasons for developing thrombosis, however some causes
could result in enhancing the risk of it.
Inactivity
- The chances of blood clotting due to slow down of the blood circulation flow have
its origin in inactivity for long periods which happens in bed-ridden patients.
Blood Vessel Damage
- Formation of blood clot due to damaged blood vessels caused by broken bones, severe
muscle injury or during surgery.
Medical & genetic conditions: These conditions include
- Treatment with chemotherapy or radiotherapy
- Heart and lung disease
- Infectious diseases like hepatitis
- Inflammatory disease like rheumatoid arthritis
- Genetic reasons
- Hughes syndrome (blood becomes abnormally “sticky”)
Pregnancy: During pregnancy the body has a tendency towards blood clot.
Contraceptive pill and hormone replacement therapy: Both of these contain
Oestrogen which has a property to clot blood more easily.
Other causes:
- Obesity
- Smoking
- Dehydrated state
- Aging resulting in reduced mobility
