Hyperemesis Gravidarum : Why not dextrose?


Question
Why you cannot give dextrose to hyperemesis gravidarum patient?

Answer
Dextrose containing solutions should be avoided as they increase the body’s requirements for thiamine and thus increase the chance of precipitating Wernicke encephalopathy in a woman who is already thiamine deficient

===============================

additional information from wong yee ming

Dextrose infusion can always be considered if the patient is too hypoglycemic and could not tolerate orally. All we need is to supplement them with thiamine (IV thiamine can be given), preferably before dextrose infusion, although it's just to appease the myth that thiamine should be given before dextrose infusion. It's all based on clinical judgment, and no clear cut answer.
