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.
It takes about 6 months for hair loss to get back to normal. According to the American Pregnancy Association (APA) 40 to 50 percent of postpartum women report noticeable hair loss after having a baby.
