Hyperhidrosis (Hands)

Also known as palmar hyperhidrosis.

What are hyperhidrosis concerns?

Hyperhidrosis is a term used when sweating feels heavier than your body needs for cooling. 

It often affects: 

• Axilla (underarms) 

• Palms of the hands 

• Soles of the feet 

• Face and scalp 

• Other localised areas of the body 

Some people notice it during everyday tasks, while others see it more during stress, exercise or warm weather. A qualified healthcare professional can help assess what may be contributing in your case. 

What causes hyperhidrosis? 

There are different possible causes of hyperhidrosis. A medical assessment is important to check for any underlying health issues. 

Cause #1: Primary hyperhidrosis 
This type often starts in childhood or adolescence and is not linked to another medical condition. It is thought to relate to overactive signals from the nerves that control sweat glands. 

Cause #2: Secondary hyperhidrosis 
In some people, excessive sweating can be related to an underlying condition. Examples include some hormonal changes, infections or other medical issues. Your doctor can assess and investigate further when needed. 

Cause #3: Environmental and lifestyle triggers 
Heat, exercise, spicy foods and emotional stress can increase sweating. In people with hyperhidrosis, these triggers may cause more noticeable or frequent episodes. 

Why do I get hyperhidrosis and others don’t? 

Not everyone with the same environment or stress level will develop hyperhidrosis. Several factors may increase the likelihood. 

Factor #1: Family history 
Hyperhidrosis can run in families. If close relatives experience excessive sweating, you may be more likely to notice similar concerns. 

Factor #2: Individual nerve sensitivity 
Some people have sweat glands that respond more strongly to signals from the nervous system, even in everyday situations. 

Factor #3: Hormonal and health factors 
Changes in hormones, certain medical conditions and some lifestyle factors can contribute to sweating patterns. Your doctor can help decide whether further tests are needed. 

The impact of hyperhidrosis 

Hyperhidrosis can affect how you feel physically and emotionally. 

People often describe: 

• Damp clothing, visible patches under the arms or on the back 

• Difficulty gripping pens, tools or sports equipment when hands are affected 

• Discomfort in shoes when feet sweat more than usual 

• Worry about shaking hands or lifting their arms in public 

• Avoiding certain clothes, colours or fabrics 

• Feeling self conscious in social or work situations 

If this sounds familiar, you are not alone and support is available.
