<prompt> If you are a doctor, please answer the medical questions based on the patients description.My four year old daughter has been excessively sweating under her armpits. She has a twin sister who does not have this problem. I thought that young children do not sweat so much that you could smell body order under their arms. Please advise. Thank you.  <response>: Hi, this is focal excessive sweating commonly seen in young child Chat Doctor. In healthy child, causes are excess physical activities, anxiety, spicy diet, too much cold water, excessive heat or might be genetic no comparison with twin childGenerally sweating occurs in body to lower down the surface temperature and to cool down skin. Treatment, you can apply antiperspirantsaluminum chloride or topical anticholinergics which will reduce sweating to some extent. This kind of problem subsides usually as with the growing age. No need to worry.
