Hyperhidrosis in Hamburg: When Excessive Sweating Affects Everyday Life
Your shirt is fresh, and the meeting room is comfortably cool. Yet, even before your first appointment, you find yourself checking your armpits. Will the damp patches be visible? People who experience excessive sweating often worry about questions like these long before anyone else notices. The constant need to monitor your own body can be more exhausting than the sweating itself. Sweating is an essential protective function of the body. With hyperhidrosis, however, the body produces more sweat than it needs to regulate its temperature, even without heat or physical exertion. At our private dermatology practice on Heilwigstraße, we therefore begin by examining the underlying cause and the areas affected. Only then do we work with you to choose an appropriate treatment. You are welcome to book your initial consultation online or by phone so we can discuss the available treatment options.
How Your Hyperhidrosis Treatment Works
We ask about when the sweating began, potential triggers, family history, previous treatments, and medications, and examine the affected areas. If there are indications of an underlying medical condition, we investigate these first before discussing BTX treatment.
We identify the areas where the sweat glands are particularly active, using the iodine-starch test if necessary. A fine grid marked on the skin helps ensure that the botulinum toxin is distributed evenly without leaving untreated areas.
Using a very fine needle, we administer numerous small injections just beneath the surface of the skin, usually 15 to 20 per armpit. Significantly more injections are required for the hands. Before each treatment, a local anaesthetic cream is applied to the skin.
Sweating usually begins to improve within the first week. During your follow-up appointment, we check whether any areas are still producing excessive sweat and discuss when another treatment may be appropriate.
Primary or Secondary Hyperhidrosis: Understanding the Underlying Cause
How We Diagnose Hyperhidrosis
How BTX Works Against Excessive Sweating
Some sweat glands behave like a sprinkler system whose alarm is triggered by even the slightest stimulus. The system itself is not faulty – it simply receives the signal to activate too frequently. This signal is transmitted by a neurotransmitter called acetylcholine, which carries messages from fine nerve endings to the sweat glands. Botulinum toxin blocks the release of this neurotransmitter precisely where it is injected into the skin. The sweat glands remain intact; only the communication pathway to them is temporarily interrupted. Over time, however, the body restores the connection between the nerves and sweat glands, and the effects gradually wear off. This is why regular maintenance treatments are important.
What Studies Show About Effectiveness
Approval and Off-Label Use
In Germany, one botulinum toxin product is approved for severe, persistent underarm sweating in adults and adolescents aged 12 and over when topical treatments have proven insufficient. No botulinum toxin product is approved for treating excessive sweating of the hands, feet, or forehead. Treatment in these areas is therefore considered off-label use: it has been investigated in controlled clinical trials but falls outside the officially approved indications. Before treatment, we discuss this openly with you, including the potential benefits, risks, and available alternatives.
Who Is Suitable for Treatment?
- You have experienced excessive sweating of the armpits, hands, feet, or forehead for years, and other underlying causes have been ruled out.
- Antiperspirants containing aluminium chloride have not provided sufficient relief or have irritated your skin.
- Excessive sweating noticeably affects your professional life, social interactions, or everyday activities.
- You are looking for a treatment that does not involve surgery or downtime.
When Other Approaches Should Be Considered First
- You experience excessive sweating throughout your body, at night, or have only recently developed unusually heavy sweating. In these cases, identifying the underlying cause takes priority.
- You have not yet tried topical treatments. Clinical guidelines for hyperhidrosis recommend these as the first step, with tap water iontophoresis also recommended for the hands and feet.
- Your profession requires full hand strength and precise fine motor skills, such as playing a musical instrument or performing surgery. In these cases, we carefully weigh the benefits and risks of treating the palms.
Possible Side Effects and Contraindications
- At the injection sites: Pain, minor bruising, swelling, or irritation
- General side effects: Headaches, itching, hot flushes, or increased sweating in other areas of the body
- On the hands: Temporary reduction in grip strength or the ability to perform fine motor movements
- Uneven results: Individual areas may continue to sweat and can be treated again during a follow-up appointment
- An infection at the planned injection sites
- A known hypersensitivity to any of the ingredients in the botulinum toxin preparation
- Neuromuscular disorders such as myasthenia gravis
- Medications that affect signal transmission between nerves and muscles
- Pregnancy and breastfeeding – we generally advise against treatment during these periods
BTX or Another Hyperhidrosis Treatment?
Treatment | How It Works and When It Is Used | Antiperspirants | Products containing aluminium chloride are applied directly to the skin; often a first step in treatment. |
|---|---|
Prescription Cream | An anticholinergic cream may be an option for primary axillary hyperhidrosis. |
Tap Water Iontophoresis | A mild electrical current is passed through a water bath; commonly used for the hands and feet. |
BTX Injections | Locally block nerve signalling; provide temporary results and have been studied particularly extensively for underarm sweating. |
Oral Medications | Used in selected cases; may cause systemic side effects, such as dry mouth. |
Surgical / Device-Based Procedures | Considered only after careful evaluation; depending on the method, they may have permanent consequences or cause compensatory sweating. |
