Why does excessive sweating occur?
Excessive sweating – known medically as hyperhidrosis – means the body produces more sweat than necessary, even at rest, in normal temperatures or without exercise.
There are two main types: Primary hyperhidrosis is when the sweat glands work overtime without an underlying medical reason.
Secondary hyperhidrosis is caused by another condition or certain medications.
A medical check makes sense if you …
- sweat heavily even at rest – for example on the armpits, hands or feet
- often have to deal with wet clothing or sweaty palms
- break out in sweat even though it’s neither hot nor physically demanding
- suspect your sweating might have a medical cause (hyperhidrosis)
- want medical treatment because home remedies or antiperspirants don’t help
What happens during treatment for excessive sweating?
The dermatologist examines the affected areas and rules out possible internal causes – for example, through blood tests or questions about medications, thyroid issues or hormone levels.
What happens during treatment?
Depending on how severe the sweating is, we offer different options:
Botulinumtoxin is injected into the affected skin to temporarily block the sweat glands. The effect lasts for several months.
For sweating on the hands or feet, we can use tap water iontophoresis – a medical water bath with mild electric current that reduces sweat gland activity.
In milder cases, we also advise on special skincare products, useful habits and other supportive treatments.
How does the treatment process work?
Initial consultation & skin examination
At your first appointment, we’ll talk in detail about your symptoms. The dermatologist examines the affected areas and checks whether it’s primary or secondary hyperhidrosis.
Treatment recommendation
Depending on location and severity, Botulinumtoxin, iontophoresis or supportive skincare advice may be appropriate. We explain clearly which option suits your needs.
Treatment
Treatment takes place directly at our clinic. Botulinumtoxin injections usually take just a few minutes and can be done discreetly. Iontophoresis sessions are started here with professional guidance.
Follow-up care & support
We continue to support you after treatment starts: We regularly assess how well it’s working, how long the effect lasts, and adjust the treatment if needed.

FAQ – Common Questions About Excessive Sweating
What is hyperhidrosis?
Hyperhidrosis is the medical term for excessive sweating – unrelated to heat, movement or exertion. It often affects the armpits, hands, feet or face. The condition is not dangerous, but can be very distressing. With targeted treatment, sweating can often be reduced.
How can I recognize hyperhidrosis?
Typical signs include heavy, sudden sweating – usually symmetrical and without an obvious reason. Affected areas may be constantly or intermittently damp, leading to skin irritation, discomfort or social challenges.
What causes excessive sweating?
There are two main types:
- Primary hyperhidrosis: usually begins in adolescence and is not caused by another condition.
- Secondary hyperhidrosis: results from another illness or medications.
A medical evaluation helps clarify the cause.
When should I see a doctor for heavy sweating?
If sweating affects your daily life, suddenly changes, or occurs with other symptoms like fever, weight loss or heart palpitations, you should see a doctor – such as a specialist in dermatology.
How is hyperhidrosis treated?
Treatment depends on how severe the sweating is and where it happens. Options include:
- Antiperspirants with aluminum chloride
- Tap water iontophoresis (especially for hands and feet)
- Botulinumtoxin injections to block sweat glands
- Medications
- In rare cases: surgery (e.g. sweat gland removal)
What is tap water iontophoresis?
This involves placing hands or feet in shallow water baths with a mild electric current. This reduces sweat production and works especially well for hands and feet.
Is iontophoresis painful or risky?
The procedure is generally well tolerated – usually you feel only a slight tingling. It’s considered safe, but shouldn’t be used by people with certain conditions like pacemakers or during pregnancy.
How often do you need iontophoresis?
Initially, treatment is done several times per week. Once it starts to work, 1–2 sessions per week are enough to maintain results. With regular use, sweating can be significantly reduced.
