Definition
- clinical dx - consistent hx and loss of 5% or more of pre-pregnancy weight; associated w/ ↑ βhCG (eg, twin pregnancies); presents during weeks 4-10.
- first check βhCG levels to rule out molar pregnancies (also a cause of hyperemesis).
- can be associated with mild elevations of liver enzymes; amylase & lipase also ↑ (from salivary gland 2° to vomiting).
- initial tx - avoidance of triggers, ginger lollipops, tea, acupressure/puncture, and saltines w/ small, frequent meals.
- if above measures are ineffective & nausea is the only complaint then pyridoxine (effective for nausea.
- pyridoxine-doxylamine (B6-antihistamine combo) works for N&V.

Definition
