Heparin-induced thrombocytopenia (HIT) occurs in up to 1% of patients receiving unfractionated heparin. HIT may occur even when very-low-dose heparin (eg, used in flushes to keep IV or arterial lines open) is used. The mechanism is usually immunologic.
The hair loss can seem more extreme if your hair grew much more than normal during pregnancy, or if you have long hair. Most women will return to their usual hair growth cycle within six months, or between 6 and 12 months after birth.
Hair usually begins falling out two to four weeks after you start treatment. It could fall out very quickly in clumps or gradually. You'll likely notice accumulations of loose hair on your pillow, in your hairbrush or comb, or in your sink or shower drain. Your scalp may feel tender.
