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.
Most changes in hair growth return to normal after the baby is born; it is common, however, for hair loss or increased shedding to occur in the first few months or first year postpartum as hair follicles and hormone levels regulate themselves without the influence of pregnancy hormones.
