The International Colloquium on HG in London (Oct 5-6) was a great success! Two presentations (1, 2) explained how ketones should not be required to be diagnosed with HG or given treatment. Some women are denied IV fluids if they do not have ketones.
What are ketones? They are produced when the body is starving and uses fat versus carbohydrates as fuel.
Ketones do not always correlate with weight loss or symptoms severity. They do predict a longer duration of hospitalization.
