Hi Ladybug,
Clotting issues are well established in thal major and intermedia but given no relevance in thal minor. However, it does seem that many thal minors do experience clotting issues, most commonly during pregnancy, but your experience seems extreme. Have blood tests showed anything unusual beyond thal minor, such as high platelets or a high rate of hemolysis? Do you have the results of any blood work that has been done?
