Excessive Sweating in Children – Causes, Symptoms and Treatment

Summer brings along a reason to rejoice. Be it the summer holidays, the picnics, the evening outings, the surprise rains, or the ice cream treats; summers have something for all. But some children may never find summers welcoming. Why is that so? Because the over excessive sweating could ruin their happy times. But, did you know there is a condition that causes excessive sweating? It’s called Hyperhidrosis. Let’s take a look at what it is.

What Is Hyperhidrosis?

Hyperhidrosis is a disorder that triggers hormonal imbalance that, in turn, causes the body to sweat profusely. Common in children, hyperhidrosis can lead to irritation in kids. This condition may lead to oozing out of body fluids from the underarms, hands, forehead, feet, or even the soles.

A study suggests that hyperhidrosis is not necessarily due to exertion or heat. Rather it is a disorder that could arise due to some medical problem too. Read on to find everything related to this common problem.

Types of Excessive Sweating

Excessive sweating can be generally categorised into the following types:

1. Generalised Excessive Sweating

This is a more serious type of sweating where your kid may sweat to an extent where even his clothes would soak and stick to the body. This type of sweating normally occurs in every part of the body.

2. Local Excessive Sweating

This type of sweating may not pose that big an issue as it oozes out body fluid from mainly one part, be it armpits or facial sweat.

3. Primary Hyperhidrosis

This is the type of sweating that is not triggered due to a side effect of any drug. This type of sweating is more common in kids.

4. Secondary Hyperhidrosis

Just the opposite of primary hyperhidrosis; secondary hyperhidrosis is caused due to a side effect of a medication or medical condition. This type of sweating is more common in adults.

How Much Sweating Is Normal in a Child?
