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.
Normally, about 85 to 95 percent of the hair on your head is growing and the other 5 to 15 percent is in a resting stage. After the resting period, this hair falls out â often while you're brushing or shampooing it â and is replaced by new growth. An average woman sheds about 100 hairs a day.
