Hi well come to HCM.
There is difference between low Wt and undernourished or mal nourished.If your
daughter is physically and mentally well balanced, if you do not find any abnormality
in his study concentration, if she is not lethargic in acting,if no recurent illness,need
not worry much she will componsate her Wt later on. How ever for general health
diet rich in portein and carbohydrate
will help you improve general health. Thanks
