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.
While you are pregnant, the majority of your hair goes into the growing phase and after you deliver, the majority of your hair goes into the resting phase. Once in the resting phase for about 3 months, the hair falls out and a new hair will grow in its place. This process will correct itself in 6-12 months.
