detailed physical check up required..

Detailed Answer:
Dear XXXXXXX Welcome to HCM,

I can understand your concern for your daughter,

Now to comment further in this context , several specific information's required :

How much was her weight 2 months before considering the current weight as 20KG ?

Please measure the height currently as well as try to recollect what was the previous height ..

Kids have several growth spurts and during the third year of life(she's already in that phase), most toddlers gain about 4 pounds (1.8 kilograms) and grow about 2 to 3 inches (5 to 8 centimeters) , so if she fits in that range then it's normal.

If you still think that it's beyond that , then the first thing you need to check is her diet habits , every small things matter in this case. As kids tend to have a tendency to put anything in to mouth so you have to be vigilant about that ..

Specially be careful of any junk food items which she's fond of and keeps on eating them every now and then..

Another important thing is Sleep and physical activity. Outdoor activities instead of indoor games should always be encouraged and practised in a kid..

If you still feel that none of the things mentioned above are unaltered , then some hormonal problem is to be suspected , and for that she should be taken to Endocrinologist to get a detailed physical examination as well as metabolic parameters (like Thyroid profile, Cortisol level, Complete blood count, Urine routine microscopy and a few others) checked .

I hope now the things are clear to you, in case of any doubts please get back to me ..

Kind Regards
