Do pregnant women produce more ketones? i heard high ketones can cause a false positive etg test

Yes and yes: All women produce ketones more easily during pregnancy. Ketones result when body fats are broken down for energy instead of sugar. So ketosis & diabetic ketoacidosis or DKA can occur more rapidly in women w/diabetes when they are pregnant. Ketones cross the placenta & affecdt the fetus. This can be avoided if blood sugars are in good control. It is possible to cause a false positive etg test.
