Hi, I'm just starting to come out of my shell and join the pregnancy forums.

I have access to online medical journals so here is some info. from a journal article. Penny Sheehan is an obstetrician and Head, Maternity Care Program, and Clinical Research Fellow, at the RWH Melbourne.

Hyperemesis gravidarum: Assessment and management
Penny Sheehan. Australian Family Physician. Melbourne: Sep 2007. Vol. 36, Iss. 9; pg. 698, 4 pgs

Outcomes have improved with intravenous rehydration therapy........
Consequences include decreased quality of life, time off work and secondary depression. [I'm sure you already know that]

DISCUSSION: It is important to exclude other causes of nausea and vomiting such as urinary tract infection and thyrotoxicosis. Assessment of severity by checking for ketones is important as severity determines management. Management will include rehydration (intravenous or oral). Evidence is lacking regarding dietary and lifestyle recommendations but some women find them useful. Pyridoxine [which is Vitamin B6] and metoclopramide (category A) are first line in treatment of hyperemesis gravidarum followed by prochlorperazine (category C), prednisolone (category A), promethazine (category C) and ondansetron (category B1). Benefit has been reported with the use of ginger. Evidence is mixed regarding acupressure and acupuncture.

It might be worth getting Vitamin b6 levels checked and get an MSU done. Urinary infections are not always symptomatic. I also read about ensuring that you are well hydrated to prevent morning sickness, from one of those ‘water can cure many diseases’ websites (although I’m not sure if it’s well backed by studies). Vicious cycle if water doesn’t even stay down. I’d possibly be pushing for IV hydration a lot earlier than when the doctor decides.

Good luck, hope this helps.
