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.
About 50 to 100 hairs fall out each day while you're washing your hair, brushing or combing it, or just sitting still. But don't worry, new hairs are constantly replacing those that have fallen out. Each hair on your head grows for about 2 to 6 years.
