Hyperhidrosis Treatment: Diagnosis & Management of Excessive Sweating
A clear guide to hyperhidrosis, a condition causing sweating beyond what is needed to regulate body temperature, and the treatments that help manage it.
Treatment usually begins with
Assessment
Cause Evaluation
Topical & Procedural Therapy
Long-Term Management Plan
Treatment starts with topical antiperspirant therapy, escalating to procedural options such as injections for more significant or localised excessive sweating.
You may need this evaluated if...
A dermatology evaluation is recommended when you notice:
- Sweating that soaks through clothing regularly
- Excessive sweating affecting the palms, soles or underarms specifically
- Sweating causing social or professional difficulty
- Excessive sweating not improving with regular antiperspirants
Hyperhidrosis is a manageable condition, with a range of effective treatments available to significantly reduce excessive sweating.
What is Excessive Sweating (Hyperhidrosis)?
Hyperhidrosis is excessive sweating beyond what is needed for normal temperature regulation, most often affecting the underarms, palms or soles, and can usually be effectively managed with an escalating treatment approach.
Often Localised to Specific Areas
Hyperhidrosis most commonly affects the underarms, palms or soles rather than the whole body.
Treatment Follows a Stepwise Approach
Options progress from stronger antiperspirants to procedural treatments if needed.
Injectable Treatment Offers Longer Relief
A targeted injectable treatment can significantly reduce sweating in a treated area for several months at a time.
An Underlying Cause Is Sometimes Considered
In select cases, an underlying medical cause for excessive sweating is evaluated.
Common Symptoms
- Sweating beyond what temperature or activity would explain
- Sweating soaking through clothing
- Cold, clammy palms or soles
- Sweating triggered by stress or anxiety
What Increases Your Risk
A combination of genetic, environmental and lifestyle factors can increase the likelihood of this skin condition.
How It Is Diagnosed
A dermatological examination, often supported by targeted tests, confirms the diagnosis and guides treatment.
Clinical History & Examination
A dermatologist assesses the pattern, extent and triggers of excessive sweating.
Starch-Iodine Test (Select Cases)
Helps map the specific area and extent of excessive sweating.
Underlying Cause Screening
Considered when sweating is generalised or has other associated features.
Severity Assessment
Guides the choice of the most appropriate treatment approach.
Treatment Approaches
Medical & Topical Management
- Prescription-strength antiperspirants
- Topical or oral medication for more significant sweating
- Botulinum toxin injections for localised, resistant sweating
- Iontophoresis for excessive sweating of the hands or feet
Procedural & Dermato-Surgical Care
A surgical procedure to interrupt the nerve signals causing excessive sweating is considered only for select, severe cases not responding to other treatments.
Treatment is tailored to your specific skin type, severity and how you respond, not a one-size-fits-all regimen.
Know When to Act
Recognising these signs early and seeking timely dermatology care helps prevent scarring and long-term skin damage.
Book an Assessment
Schedule a consultation for a routine evaluation or ongoing concern.
- Mild sweating manageable with regular antiperspirants, seeking additional options
Seek Urgent Care
Reach out for urgent care if you notice any of the following.
- Sudden onset of significant sweating, particularly with other new symptoms, warranting evaluation
