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.
