What is hyperhidrosis?
“As many as 3 in every 100 Australians have excessive sweating” (Healthdirect, 2019).
Hyperhidrosis is the medical terminology used to describe the medical condition involving excessive and uncontrollable sweating. Some people with hyperhidrosis experience sweating generally (all over the body) or focally (occurs in certain areas only).
Primary hyperhidrosis mostly starts in childhood or by adolescence. This type of hyperhidrosis if often hereditary and effects other members of the family. Secondary hyperhidrosis is less common and can occur at any age.
What areas does hyperhidrosis commonly effect?
Hyperhidrosis commonly effects the face, hands, feet, underarms and groin. Hyperhidrosis can occur on its own (primary), or be due to medications, medical conditions or injury (secondary).
What is the cause of Hyperhidrosis?
Hyperhidrosis is thought to be a genetic condition with approximately a third of patients having other family members affected.
Primary hyperhidrosis is caused by faulty nerve signals that trigger eccrine sweat glands to become overactive. It usually affects the palms, soles, underarms and sometimes the face. Whilst secondary hyperhidrosis is caused by an underlying medical condition or by taking certain medications, such as pain relievers, antidepressants, and some diabetes and hormonal medications. This type of hyperhidrosis may cause sweating across the whole body.
What can trigger hyperhidrosis?
Some triggers include: hot environments, anxiety, consumption of caffeine, alcohol, spicy foods etc.

Botulinum Toxin Injections for Axillary Hyperhidrosis
Treatment with botulinum toxin are performed by our dermatologist. These work by blocking the message that our nerves send to trigger the sweat gland. This treatment is subsidised by medicare for eligible patients when performed by a Dermatologist. Treatments can be performed every 4 months. Treatment is performed by a series of small injections in the underarm to directly effect the sweating region.
Treatment is performed via a series of small injections under the arms directly into the sweating region.
Most patients start to notice a reduction in sweat within one week following treatment however some patients may take up to two weeks to notice results. Results on average will last six months however for patients with their initial treatment may notice that results last four months.
Iontophoresis for hand and feet hyperhidrosis
Iontophoresis is used for the treatment of hyperhidrosis (excessive sweating) in focused areas such as the feet and hands. Some iontophoresis devices can treat the axilla area; however, this is less effective than treating the hands and feet.
- Ions produced by iontophoresis might physically block the sweat ducks located in the stratum corneum.
- The electrical current produced by the outside source (ionto machine) might disrupt the normal sympathetic nerve transmission
- The accumulation of hydrogen ions causes the pH in the sweat glands to drop
