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.
From the clinical perspective, Dr. Greves explained that this hair-loss period typically occurs one to five months after the baby is born, and usually resolves within 15 months postpartum. In my case, I'm happy to report that the resolution appears to be coming much quicker.
