What is a primary concern for a patient with untreated severe morning sickness?

In the context of severe morning sickness, also known as hyperemesis gravidarum, dehydration is a primary concern due to the excessive vomiting that often accompanies this condition. When a patient experiences severe morning sickness, they may frequently be unable to keep food or fluids down, leading to a significant loss of fluids and electrolytes.

Dehydration can occur quite rapidly in these cases, with effects that can exacerbate other health issues. It can cause imbalances in electrolytes that are critical for various bodily functions, potentially leading to complications such as reduced kidney function or electrolyte disturbances that may impact heart rhythm.

Although increased heart rate, low blood pressure, and anemia can be associated with dehydration or other complications, the direct consequence of severe morning sickness is typically a risk of dehydration. Thus, careful monitoring and rehydration strategies become essential in managing a patient with untreated severe morning sickness to ensure both maternal and fetal health.
