Hyperhidrosis Treatment: The Complete Guide to Excessive Sweating & Professional Treatment
Hyperhidrosis is a condition characterised by excessive sweating beyond what is normally required to regulate body temperature.
While sweating is an essential and completely normal bodily function, people with hyperhidrosis can experience significantly greater levels of perspiration, sometimes even when they are not hot, exercising or experiencing an obvious trigger.
For some people, excessive sweating can affect everyday activities, clothing choices, work, social situations and confidence.
A range of approaches may be considered for managing hyperhidrosis, including topical treatments, medicines and specialist procedures. Botulinum toxin is one treatment that may be considered for certain areas of excessive sweating following appropriate assessment.
In this guide, we explore hyperhidrosis, why it occurs, common treatment options and the professional considerations surrounding botulinum toxin treatment.
What Is Hyperhidrosis?
Hyperhidrosis is the medical term used to describe excessive sweating.
The body contains millions of sweat glands, which play an important role in regulating temperature. When body temperature rises, the nervous system stimulates sweat glands to produce perspiration. As the sweat evaporates from the skin, it helps cool the body.
In hyperhidrosis, sweating occurs excessively in relation to the body’s normal cooling requirements.
The condition can affect particular areas of the body or, in some cases, be more widespread.
What Causes Excessive Sweating?
Hyperhidrosis can occur for several reasons, and identifying the possible cause is an important part of assessment.
The nervous system controls sweat production, particularly through signals sent to eccrine sweat glands.
In some forms of hyperhidrosis, these signals stimulate excessive sweat production even when additional cooling is not required.
However, excessive sweating can also occur because of another medical condition or as a side effect of certain medicines.
For this reason, practitioners should not simply assume that persistent excessive sweating is cosmetic in nature.
Primary and Secondary Hyperhidrosis
Hyperhidrosis is generally divided into primary and secondary forms.
Primary Hyperhidrosis
Primary focal hyperhidrosis commonly affects specific areas of the body and is not caused by another identifiable medical condition.
Frequently affected areas include:
- Underarms
- Palms
- Soles of the feet
- Face and forehead
Symptoms may begin during childhood or adolescence and can sometimes run in families.
Secondary Hyperhidrosis
Secondary hyperhidrosis occurs as a consequence of another factor, such as an underlying health condition or medication.
It may affect larger areas of the body and can sometimes occur during sleep.
New, unexplained or widespread excessive sweating therefore warrants appropriate medical assessment rather than immediately proceeding with an aesthetic treatment.
Common Areas Affected by Hyperhidrosis
Although excessive sweating can occur throughout the body, focal hyperhidrosis frequently affects particular areas.
Axillary hyperhidrosis affects the underarms and can result in visible perspiration through clothing.
Palmar hyperhidrosis affects the hands and may interfere with activities such as writing, handling equipment or shaking hands.
Plantar hyperhidrosis affects the feet.
Craniofacial hyperhidrosis affects areas of the head and face.
The appropriate management approach can differ depending upon the area involved and the individual circumstances of the patient.
How Is Hyperhidrosis Diagnosed?
Assessment involves more than simply determining whether someone believes they sweat excessively.
A healthcare professional may consider factors such as:
- Where excessive sweating occurs
- How long symptoms have been present
- How frequently they occur
- Whether symptoms occur during sleep
- Possible triggers
- Current medications
- Relevant medical history
- Whether other symptoms are present
- The impact sweating has on everyday life
Where secondary hyperhidrosis is suspected, further medical investigation may be appropriate.
Correct assessment is particularly important before considering treatments such as botulinum toxin.
Treatment Options for Hyperhidrosis
Treatment depends upon the type and severity of hyperhidrosis, the area affected and the individual’s medical circumstances.
Management options can include strong antiperspirants containing aluminium salts, iontophoresis, certain medicines and botulinum toxin injections. In selected severe cases, specialist procedures or surgery may also be considered.
Treatment is therefore not one-size-fits-all.
A qualified healthcare professional should determine which options are appropriate following assessment.
How Is Botulinum Toxin Used for Hyperhidrosis?
Botulinum toxin is perhaps best known for its use in reducing the appearance of certain facial lines, but it also has established medical applications.
One such application is the management of excessive sweating.
Sweat glands receive chemical signals from nerves instructing them to produce sweat. Botulinum toxin can temporarily interfere with the transmission of these signals within the treated area.
As a result, sweat production in that area can be reduced temporarily.
The treatment does not permanently remove or destroy sweat glands.
How Does Botulinum Toxin Reduce Sweating?
Botulinum toxin works by blocking the release of acetylcholine from nerve endings.
Acetylcholine is involved in signalling eccrine sweat glands to produce sweat.
By temporarily reducing this signalling within the treated area, sweat production can be substantially reduced.
Eventually, nerve signalling recovers, meaning the effects of treatment gradually wear off.
This is why botulinum toxin treatment for hyperhidrosis generally needs to be repeated if continued symptom control is desired.
What Happens During Hyperhidrosis Treatment?
Treatment should begin with an appropriate consultation and assessment.
This includes establishing whether treatment is suitable, reviewing relevant medical history, discussing expectations and explaining potential risks and alternatives.
Where botulinum toxin is appropriate, multiple small injections are administered across the treatment area according to the prescribed treatment plan.
The precise treatment approach depends upon factors including the anatomical area being treated and the product being used.
Practitioners should work only within their competence, professional scope, prescribing arrangements and applicable regulatory requirements.
How Long Do Results Last?
Botulinum toxin does not permanently stop excessive sweating.
Improvement generally develops following treatment rather than occurring immediately, and the duration of benefit varies between individuals.
When the effects gradually diminish, sweating can return and further treatment may be considered following reassessment.
Patients should therefore be given realistic expectations rather than being promised a particular duration of results.
Who May Be Suitable for Treatment?
Suitability must always be assessed individually.
Someone experiencing persistent focal excessive sweating that significantly affects their quality of life may potentially benefit from professional assessment and discussion of available treatment options.
However, excessive sweating can occasionally indicate an underlying medical problem.
Any unexplained change in sweating pattern, particularly widespread or night-time sweating or sweating accompanied by other concerning symptoms, should be appropriately investigated.
Contraindications and Precautions
Not everyone is suitable for botulinum toxin treatment.
A comprehensive consultation should consider the patient’s medical history, current medicines, previous reactions to treatment, allergies and other relevant factors.
Treatment may need to be avoided or postponed in certain circumstances, including where there is infection at the proposed injection site or where particular medical conditions or medicines make treatment unsuitable.
The prescriber and treating practitioner must assess contraindications according to the specific botulinum toxin product being considered.
Possible Side Effects and Risks
As with any injectable treatment, botulinum toxin treatment carries potential risks and side effects.
These vary depending upon the treatment area but can include temporary discomfort, tenderness, swelling or bruising around injection sites.
Other adverse effects are possible, and patients should receive appropriate information during consultation and know when and how to seek medical advice.
Practitioners must also be trained to recognise and appropriately manage complications within their professional scope.
Hyperhidrosis Treatment Aftercare
Patients should receive clear aftercare appropriate to the product and area treated.
They should understand what reactions may normally occur following treatment, when improvement might be expected and what symptoms would require further assessment.
Good aftercare also includes providing an appropriate route for patients to contact their practitioner if they have concerns following treatment.
What Should Professional Hyperhidrosis Training Cover?
Professional education should extend considerably beyond learning where injections are placed.
Training should develop an understanding of areas including:
Anatomy and physiology – understanding sweat glands, relevant anatomy and the mechanisms controlling perspiration.
Understanding hyperhidrosis – recognising different presentations and potential causes of excessive sweating.
Consultation and assessment – identifying appropriate candidates and recognising situations requiring medical referral.
Botulinum toxin pharmacology – understanding how the medicine works and its limitations.
Contraindications and precautions – recognising when treatment may be inappropriate.
Treatment planning – understanding professional assessment and treatment principles.
Adverse effects and complications – recognising potential problems and responding appropriately.
Aftercare and follow-up – supporting patients following treatment and assessing outcomes.
Professional responsibilities – understanding prescribing, consent, insurance, record keeping and applicable regulatory requirements.
Good education should teach practitioners why treatment decisions are made rather than simply providing an injection pattern to copy.
Adding Hyperhidrosis Treatment to an Aesthetics Practice
For appropriately qualified practitioners, hyperhidrosis treatment can broaden the range of services available within an aesthetics or medical aesthetics practice.
It also represents a different type of patient need from purely appearance-focused aesthetic treatments.
However, because botulinum toxin is a prescription-only medicine in the UK, practitioners must ensure that their prescribing and treatment arrangements comply with current professional, legal and regulatory requirements.
Appropriate insurance, training, patient assessment, consent, documentation and complication management procedures are also essential.
Learn Professional Hyperhidrosis Treatment
Understanding hyperhidrosis requires more than learning how to administer a product.
Practitioners should understand why excessive sweating occurs, how patients are assessed, when treatment may be appropriate and when someone should instead be referred for further medical assessment.
