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.
That fine hair is called lanugo.. It's commonly produced during the last stage of pregnancy and most full-term babies are born with it. It tends to cover certain parts of the body, including the back, shoulders, ears, and forehead. Lanugo usually falls off during the first weeks of life but may remain for as long as a few months.
