What is the pH of the blood in a severe case of hyperemisis?

Answer 1

In extreme cases of Hyperemesis (Gravidarum) which is like morning sickness only much much worse, the blood pH can dip below 7.3 due to serum bicarbonate being lowered. It varies with the bouts of vomitting.

However, after a severe bout of vomitting the swing can be to alkylosis so if an attempt is made to replace fluids, the physician has to be very careful to balance needs for sodium and glucose against the patient's present pH.

There seems to be no known cause of it right now. It has been blamed on psychological causes and bacteria, but neither are demonstrably causative.

It can be very frightening to be around. It can lead to dehydration and possible miscarriage. The exact number of cases are unknown since many are not hospitialized.

Answer 2

if memory serves me correct it would drop some towards the acidic side, maybe 7.2 or so my school of thought is that if the pt is vomiting in turn causing rapid dehydration so the fluid shift would cause a concentration of their blood supply, hence an acid build up.
I actually started reading about this and read that in hyperemisis gravideum that the pt may get ketosis, if that occurs i would think the Ph would shift high then since they start blowing off H ion not sure on that thought though.
