Underarm Hyperhidrosis: Understanding and Treating Excessive Sweating

Underarm hyperhidrosis, or excessive sweating, not only causes physical discomfort but also poses significant social and emotional challenges. Those affected often face daily struggles with visible sweat marks, which can undermine confidence and complicate social interactions.

Understanding Excessive Sweating (Hyperhidrosis)

Underarm excessive sweating is characterised by uncontrollable sweating in the armpits, significantly exceeding the body’s needs for temperature regulation. This condition affects comfort, day-to-day activities, and social interactions, often leading to anxiety and self-consciousness about body odour and sweat stains.

underarm hyperhidrosis

The exact cause of primary underarm hyperhidrosis is still not fully understood. However, it is believed to be related to overactivity in the sympathetic nervous system, specifically in the nerves that trigger sweat glands in the underarms. This condition can be exacerbated by stress, emotion, or physical activity, but excessive sweating often occurs without any apparent triggers.

Impact on Daily Life

The effects of underarm hyperhidrosis extend beyond physical discomfort, affecting individuals’ social life, choice of clothing, professional activities, and self-esteem. The persistent worry about sweat marks can deter individuals from participating in social or professional engagements, leading to social withdrawal and isolation.

Treatment Necessity

While everyone sweats, the volume and uncontrollability in hyperhidrosis prompt those affected to seek effective treatment solutions. Over-the-counter products and home remedies may offer temporary relief, but they seldom address the condition’s root cause or provide lasting results.

Home Remedies

Home remedies are often the first line of defence against underarm hyperhidrosis, but their effectiveness is generally limited and inconsistent. Many individuals turn to solutions such as over-the-counter antiperspirants, herbal concoctions, dietary changes, and homemade remedies in hopes of finding relief. Here’s a closer look at why these remedies might not be as effective as professional treatments:

Over-the-Counter Antiperspirants

Standard antiperspirants may provide temporary relief for mild sweating but are typically insufficient for severe hyperhidrosis. They must be applied frequently and can cause skin irritation or discomfort, limiting their usability and effectiveness over time.

Herbal and Natural Remedies

Herbal remedies, like sage tea or witch hazel, are often touted for their natural sweat-reducing properties. However, these methods lack the potency needed to control severe sweating and offer no long-term solution, as their astringent properties can only address symptoms superficially.

Dietary Adjustments

Some advocate for dietary changes to manage sweating, such as avoiding caffeine and spicy foods. While such adjustments might reduce sweating marginally in some individuals, they do not address the hyperactive sweat glands and therefore do not provide a definitive or reliable solution for hyperhidrosis.

Truth About Home Remedies

The primary limitation of home remedies is their inability to treat the underlying causes of hyperhidrosis. They often serve merely as temporary fixes, requiring continual and often increased usage to maintain even modest effects. Furthermore, without addressing the excessive activity of the sweat glands, these remedies cannot alter the condition’s course or provide significant, long-lasting relief.

Professional Treatments

Injection treatments at our clinic represent a highly effective solution for managing underarm excessive sweating. Our hyperhidrosis treatments involve administering a specific solution directly into the affected area, which significantly reduces sweat production by temporarily blocking the nerves that stimulate the sweat glands. Here’s why choosing this method could be the best option for tackling excessive underarm sweating:

Targeted and Effective

The precision of injection treatments allows for targeted action specifically in the underarms, where excessive sweating is most problematic. This localised approach ensures that the active ingredients are delivered exactly where they are needed, maximising the efficacy of the treatment and minimising side effects elsewhere on the body.

Quick Procedure with Lasting Results

One of the key advantages of injection treatments is the speed and convenience of the procedure. Typically completed in just one short visit to our clinic, the treatment involves minimal discomfort and allows patients to return to their daily activities almost immediately, with no downtime required. The results are noticeable within days and can last for several months, providing long-term relief from excessive sweating.

Safe and Minimally Invasive

The injections are a safe and minimally invasive treatment option. They have been extensively studied, showing a high safety profile with very few risks or side effects. This makes it a preferable choice for many patients who are looking for a reliable and effective solution without the need for surgical interventions.

Improved Quality of Life

The dramatic reduction in sweating allows individuals to regain confidence and comfort, freeing them from the constant concerns about visible sweat marks and body odour. This improvement in symptoms significantly enhances quality of life, enabling more freedom in social and professional environments.

Expected Results

Choosing injection treatments for underarm hyperhidrosis at our dermatology clinic in London offers transformative results that significantly enhance your quality of life. Here’s what you can expect in terms of outcomes and the benefits that follow post-treatment:

Immediate and Long-Lasting Relief

One of the most compelling advantages of our injection treatment is the rapid onset of results. Most patients begin to notice a decrease in underarm sweating within just a few days after the procedure. The effects are not only immediate but also enduring. A single treatment session can provide relief from excessive sweating for up to several months, depending on individual responses.

Boost in Confidence and Social Freedom

Perhaps the most significant benefit of successful hyperhidrosis treatment is its profound impact on confidence and social interactions. Patients often report a dramatic improvement in their ability to engage in social and professional activities without the fear and embarrassment of excessive sweating. The treatment can eliminate concerns about body odour and visible sweat marks, providing a new sense of freedom in your personal and professional life.


While the initial cost of the treatment might seem like an investment, it is cost-effective in the long run. The durability of the results means fewer treatments over time and less reliance on daily antiperspirants and frequent clothing changes. This can lead to savings that offset the cost of the injections.


What should I expect during my initial consultation?

During your initial consultation, our dermatologist will evaluate your medical history, discuss your symptoms, and determine if injection treatments are suitable for you. This is also an opportunity for you to ask any questions and understand the procedure, its benefits, and any potential risks.

How long does each treatment session take?

Each injection treatment session typically takes about 20 to 30 minutes. The process involves preparing the area, administering the injections, and providing post-treatment care instructions.

Is the injection treatment painful?

The injection treatment involves minimal discomfort. Most patients describe the sensation as a small pinch or sting. Numbing creams or ice packs can be used to reduce any discomfort during the procedure.

How soon can I return to normal activities after the treatment?

You can return to most of your normal activities immediately after the treatment. It is advised to avoid intense physical activities and sauna or steam rooms for 24 hours post-treatment.
