There are two different types of excessive sweating or hyperhidrosis in medical terms:


Primary Hyperhidrosis

Primary Hyperhidrosis refers to a condition in which there is sweating only in the armpits, palms of the hands and feet.

Children with primary hyperhidrosis typically don’t sweat while sleeping.

For instance, children having diabetes, infections or any sort of other medical conditions have chances to suffer from secondary hyperhidrosis.  

Causes of Hyperhidrosis In Children

Sweating is the internal mechanism to control the elevating temperature of the human body. The nervous system automatically initiates perspiration in the sweat glands.

The internal body’s heat starts liberating out of the body. Sweating of palms may occur when the person feels nervous or excited.

However, there are certain metabolic or neurological conditions to initiate the condition of child excessive sweating.

Complex health disease or excessive emotion can cause your child’s sweat glands to trigger causing excessive sweat in their body.

When your child suffers from hyperhidrosis, the nerves responsible for the sweat glands become overactive and initiate excess sweat.

In addition, this condition worsens when your child is under extreme stress, tension or on atmosphere having high temperature.

Some of the more serious causes of excessive sweating in young children include:



Any type of infection whether mild or serious also can lead to causing your child with excessive sweating.
