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.
Telogen effluvium occurs when your body tells more hairs to stop growing than usual. Hairs have a grown cycle of two years before stopping and falling out two months later. If your body tells more hairs than normal to stop growing, two months later more hairs will fall out. All of these may be caused by anxiety.
