What is hyperhidrosis?
Hyperhidrosis is a condition where the body produces excessive sweat beyond what is needed for temperature regulation. It commonly affects the underarms (axillary hyperhidrosis) and palms of the hands (palmar hyperhidrosis), though other areas like the feet or face can also be involved.
Primary hyperhidrosis refers to sweating that develops on its own and usually affects specific areas such as the underarms or palms. Secondary hyperhidrosis happens when sweating is linked to another health condition or medication and often affects larger areas of the body. A clinician can help determine which type may be relevant to your situation and whether further medical assessment is recommended.
This is not related to exercise or heat. People with hyperhidrosis may sweat heavily even while resting, which can be uncomfortable and may require practical day to day adjustments.
What causes hyperhidrosis?
Primary hyperhidrosis
- The most common type
- Starts in childhood or adolescence
- Usually affects specific areas (like underarms or palms)
- Not linked to an underlying health condition
- Research suggests it may involve increased activity in the sympathetic nervous system.
Secondary hyperhidrosis
- May be associated with medical issues such as thyroid concerns, menopause, infection, or certain medications
- Usually involves generalised sweating (not just one body area)
- Requires investigation and management of the underlying condition
Why do I have hyperhidrosis and others donāt?
Factor #1 ā Genetics
Hyperhidrosis often runs in families. If a parent or sibling has it, you’re more likely to develop it too.
Factor #2 ā Nerve sensitivity
The nerves that control your sweat glands may be more easily triggered, which may contribute to increased sweating.
Factor #3 ā Stress response
Many people notice their sweating worsens during stressful, social, or emotional situations, especially with palmar sweating.
Factor #4 ā Health conditions or medications
Secondary hyperhidrosis can be caused by hormonal shifts, infections, diabetes, or antidepressants. A medical review is recommended if sweating begins suddenly or is widespread.
Living with hyperhidrosis
Excessive sweating can mean making practical adjustments day to day. Common concerns include:
- Clothing stains and odour
- Difficulty shaking hands or holding tools
- Avoiding certain clothing, fabrics, or colours
- Planning around sweating at work or socially
- Needing to shower or change frequently
- Skin irritation or infections in sweaty areas
Hyperhidrosis is a recognised medical condition. If sweating starts suddenly, affects your whole body or happens at night, see your GP.
