What you can ask for to make hospital visits more comfortable:

Women with hyperemesis are very miserable and deserve to be treated with great compassion. Extra measures taken to give comfort are beneficial both physically and psychologically. 

  • Make sure that intravenous fluids are warmed before administration to avoid discomfort and calorie loss due to shivering. 
  • Offer warmed blankets and a bed (v. reclining chair). 
  • If multiple sticks are required for an IV, consider a local anesthetic and request most skilled personnel to avoid scarring. 
  • Try medications rectally, compounded or transdermal, and avoid intramuscular injections due to muscle atrophy and low pain tolerance. 
  • Ask for a room in an area where it's quieter and the smells are minimized.
  • Ask about a PT consult for education on progressive exercise to minimize atrophy.
