Hi, Welcome to HCM, I am Dr. Das
HC means Head circumference. It should be greater than AC that is abdominal circumference. It indicates normal growth.
Protein s Deficiency
means you have a increased couagulation tendency. So you have to take Heparin
In the 19th week scan the increased HC indicates a good growth.
What about the AC? Is it increased? It is important because it is the single most sensitive parameter for IUGR
My advise is 1. take bed rest
2. 300 extra calories are to be taken everyday.
3. avoid smoking
4. serial evaluation to be done by USG.
