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 loss from menopause or childbirth often goes away after 6 months to 2 years. For hair loss due to illness (such as fever), radiation therapy, medicine use, or other causes, no treatment is needed. Hair usually grows back when the illness ends or the therapy is finished.
