Excessive and uncontrollable sweating, particularly in the underarm area (axillary hyperhidrosis), places an enormous physical and psychological strain on those affected. When conservative treatments such as specialised deodorants reach their limits, modern medicine offers permanent solutions. One of the most effective surgical methods is sweat gland suction.
This article provides a clear and comprehensive explanation of what sweat gland suction is, how the procedure works and how it differs from other common treatment methods.
What is sweat gland suction?
Sweat gland suction, also known as suction curettage, is a minimally invasive surgical procedure designed to permanently reduce sweat production in the armpits. In this procedure, the sweat glands, which lie directly beneath the skin, are physically removed using a combination of suction and scraping (curettage). As the sweat glands removed mechanically do not regrow, the effect is generally permanent. However, any remaining glands may remain active or may increase slightly as a compensatory mechanism over time, meaning that some residual sweat production may persist.
The principle behind it: dual mechanical removal
- Extraction (suction) Much like a Liposuction (Liposuction): the surgeon inserts a special, thin cannula into the subcutaneous fatty tissue of the armpit via small incisions in the skin. The suction created removes fat cells and most of the sweat glands embedded within them.
- Curettage The cannula used has a sharpened opening at its tip. After the initial suction, the surgeon guides the cannula directly beneath the skin’s surface. Through this mechanical scraping, the remaining sweat glands, which are firmly attached to the underside of the dermis, are selectively removed and also suctioned out.
Who is this procedure suitable for?
Sweat gland suction is the treatment of choice for patients diagnosed with severe axillary hyperhidrosis who:
- conservative and temporary treatments (e.g. with botulinum toxin) did not produce the desired results.
- the focus is on finding a long-term, permanent solution.
- the distress caused by excessive sweating is very severe.
A comparison of the methods: surgical, chemical or thermal?
| Criterion | Sweat gland suction (suction curettage) | Botulinum toxin injection (Botox®) | Thermal procedures (e.g. miraDry®) |
|---|---|---|---|
| Mechanism of action | Physical removal of the sweat glands | Chemical blockade of nerve signals to the sweat glands | Destruction of the sweat glands by microwave energy (heat) |
| Invasiveness | Minimally invasive surgery | Non-invasive (injections only) | Non-invasive |
| Result | Long-term / permanent | Temporary (effective for approx. 4–7 months) | Effective in the long term – repeat treatments may be necessary |
| Anaesthesia | Tumescent local anaesthesia required | No anaesthetic required, or only an anaesthetic cream | Local anaesthesia |
| Downtime | Several days to about a week (wearing a compression vest is recommended) | No downtime | A few days (swelling and redness may occur) |
Risks and the importance of appropriate financial protection
Although sweat gland suction is a very safe and effective procedure, like any operation, it carries risks.
Whether the health insurance fund covers the costs depends on the exact diagnosis, the severity of the condition and the chosen treatment method. Whilst conservative treatments such as Botulinum toxin Whilst the costs may be covered in certain cases, reimbursement for surgical procedures such as sweat gland suction is usually difficult to obtain and is not guaranteed.
One Consequential Costs Insurance can provide financial security should medically necessary follow-up treatment be required after your operation.
Frequently Asked Questions (FAQ) on sweat gland suction
The procedure itself is carried out under a special form of local anaesthesia (tumescent anaesthesia) and is painless. In the days following the procedure, you may experience some tenderness at the site of the incision and a strong feeling of tightness, which can be effectively managed with standard painkillers.
The aim is to achieve a significant reduction to a normal, socially acceptable level. A 100% level of dryness is not, and should not be, the aim, as a certain amount of residual moisture is part of normal skin function. A reduction in sweat production of 80–90% is a realistic outcome.
Compensatory sweating is a well-known but rare side effect of other procedures (e.g. sympathectomy). In the case of localised removal of sweat glands in the armpits, compensatory sweating is extremely rare and, unlike nerve procedures (e.g. ETS), occurs only in exceptional cases.
A special compression vest must be worn for about a week. You should avoid sport and heavy physical work for 3–4 weeks. Mild swelling may persist for several weeks.
