Excessive Sweating (Hyperhidrosis): Causes, Treatment & How Botox Can Help This Summer

Excessive Sweating This Summer? It Could Be Hyperhidrosis

Summer naturally means warmer weather, longer days, and more time outdoors. It's perfectly normal to sweat when it's hot or during exercise—it's your body's way of regulating temperature.

However, if you're sweating excessively even when you're sitting in an air-conditioned office, meeting friends for coffee, or simply going about your day, it could be more than just the summer heat.

Excessive sweating, known medically as hyperhidrosis, is a common condition that affects millions of people worldwide. Although many people feel embarrassed to talk about it, effective treatments are available.

What Is Hyperhidrosis?

Hyperhidrosis is a condition in which the body produces more sweat than is needed to regulate temperature. The most commonly affected areas include:

• Underarms
• Palms of the hands
• Soles of the feet
• Face and forehead

Unlike normal sweating, hyperhidrosis can occur regardless of the weather or physical activity.

Many people notice symptoms becoming more difficult to manage during summer, when excess sweating becomes even more noticeable.

How Does Hyperhidrosis Affect Daily Life?

While excessive sweating isn't usually dangerous, it can significantly affect quality of life.

People with hyperhidrosis may:

• Sweat through clothing within minutes.
• Avoid wearing certain colours or fabrics.
• Feel uncomfortable during meetings or social events.
• Worry about body odour despite good hygiene.
• Experience reduced confidence in both professional and personal situations.

Many patients tell us they've spent years trying stronger deodorants or changing their lifestyle before realising medical treatment is available.

Why Does It Happen?

Hyperhidrosis often occurs because the nerves that control the sweat glands become overactive. These nerves continue sending signals that trigger sweating even when your body doesn't need to cool itself.

In many cases, there isn't an underlying medical problem—it simply means the sweat glands are receiving more stimulation than necessary.

Can Excessive Sweating Be Treated?

Yes.

For people with excessive underarm sweating, one of the most effective treatment options is botulinum toxin injections.

Botulinum toxin works by temporarily blocking the nerve signals that activate the sweat glands in the treated area. As a result, sweat production is significantly reduced while the rest of your body's normal temperature regulation continues to function.

The treatment targets only the treated area and does not stop your body from sweating elsewhere when needed.

Does Reducing Sweating Stop My Body From Removing Toxins?

This is one of the questions we hear most often.

The answer is no.

Sweating is primarily responsible for helping regulate body temperature. Your liver and kidneys are the organs responsible for filtering and removing waste products from your body.

Reducing sweat production in one area, such as the underarms, does not interfere with these natural processes.

Is Botulinum Toxin Treatment Safe?

When prescribed following a medical consultation and administered by a qualified healthcare professional, botulinum toxin has been used safely for many years to treat hyperhidrosis.

Before treatment, we'll assess your symptoms, discuss your medical history, and determine whether you're a suitable candidate.

Every patient is different, so treatment recommendations are always tailored to individual needs.

How Long Do Results Last?

Results usually begin to develop within several days after treatment.

Most patients experience a noticeable reduction in sweating for several months, although the duration varies from person to person.

Many people say the biggest benefit isn't just staying dry—it's feeling more confident wearing the clothes they want, attending social events, and no longer worrying about visible sweat marks.

When Should You Consider Treatment?

You may benefit from a consultation if excessive sweating:

• Happens even when you're not hot.
• Soaks through clothing regularly.
• Makes you avoid certain activities or clothing.
• Affects your confidence or quality of life.
• Doesn't improve with antiperspirants.

Hyperhidrosis is a recognised medical condition, and you don't have to simply live with it.
