Low iron could lead to blood clots

Dangerous blood clots that form in a vein, known as DVT or deep vein thrombosis, could be caused by low levels of iron in the blood.

That's the finding of a new study in the journal Thorax.

DVT typically occurs in the legs and can cause pain and swelling and can be fatal if a blood clot dislodges and travels into the lungs.

This new study found patients with low iron levels were at increased risk for blood clots but those who took iron supplements did not have a higher risk.

Experts say this suggests that treating an iron deficiency may help prevent DVT in the general population.
