Type I may be inherited or acquired through such things as kidney or liver disease. Acquired cases tend to have a lower risk of blood clots compared to inherited cases.

Antithrombin prevents the blood from clotting too readily and if it is unable to function properly then the blood becomes more prone to clotting which can result in severe problems. Severity of the condition can vary amongst patients and the symptoms can vary considerably depending on the location of blood clots and size of the blood clot. Type II is an inherited condition.

The reality is that the potential harmful effects on the fetus are very small compared to the problems caused to mother and fetus if a severe asthma attack develops. Furthermore, uncontrolled asthma during pregnancy may also cause problems such as small birth weight or premature birth.
