Morning Sickness: Will Nausea Be As Severe in Second Pregnancy?

I had my first child at 22 and had severe nausea -- day and night -- throughout the whole pregnancy. What are the chances the same thing will happen with a second pregnancy?

When "morning" sickness or severe nausea and vomiting occur throughout pregnancy, we call this condition "hyperemesis gravidarum," especially if it causes weight loss, dehydration, ketone production or potassium deficiency. When this is seen, it is very important to rule out other conditions such as gastroenteritis, cholecystitis (gall bladder), pancreatitis, hepatitis, ulcer, kidney disease and fatty-liver disease.

This most often does not occur in subsequent pregnancies, especially to this degree, and if it does, I would request testing for the above conditions.

Second pregnancies are unique in terms of the different implantation site, different genetics and varying maternal adaptive responses, both physiologically and emotionally.

I have followed many women who worry that this will recur, but it usually does not. I wish you well.
