What is Excessive Sweating?

Hyperhidrosis is a medical condition characterised by excessive sweating that goes beyond what the body needs for temperature regulation. It can affect specific areas (focal hyperhidrosis) — most commonly the underarms, palms, soles of the feet and face — or the entire body (generalised hyperhidrosis). This condition affects approximately 3-5% of the population and can have a profound impact on daily life.

Living with excessive sweating is much more than a physical inconvenience. Many people with hyperhidrosis experience social anxiety, avoid certain clothing colours, struggle with handshakes, and feel constantly self-conscious. Some even limit their career choices or social activities because of their condition.

At MED-CLINIC, we understand the impact hyperhidrosis has on quality of life. Our most effective treatment is Botox (botulinum toxin) injections, which temporarily block the nerve signals that trigger sweat glands. This treatment is safe, well-established and can reduce sweating by up to 90% for 6-12 months per session.

The first step is always a thorough consultation to determine whether the sweating is primary (no underlying cause) or secondary (caused by another medical condition), ensuring we provide the most appropriate treatment.

"Botox for excessive sweating is one of the most life-changing treatments we offer. Clients who have suffered for years often tell us it has transformed their daily life. The procedure takes just 20 minutes and results last 6-12 months."

The Science Behind Excessive Sweating

The sympathetic nervous system controls sweating through the neurotransmitter acetylcholine. In primary focal hyperhidrosis, the eccrine sweat glands in affected areas are overstimulated by an overactive sympathetic nervous system. Botulinum toxin works by blocking the release of acetylcholine at the nerve-muscle junction, effectively preventing the nerve signal from reaching the sweat glands for 6-12 months.

Causes & Symptoms of Excessive Sweating

Causes

  • 1. Primary focal hyperhidrosis — overactive sympathetic nervous system (genetic)
  • 2. Hormonal changes (menopause, thyroid disorders, puberty)
  • 3. Medications that affect the nervous system or hormones
  • 4. Anxiety disorders and stress
  • 5. Infections and fever
  • 6. Metabolic conditions (diabetes, obesity)
  • 7. Neurological conditions affecting the autonomic nervous system
  • 8. Secondary to other medical conditions (always rule out first)

Symptoms

  • Visible sweat stains on clothing, even in cool conditions
  • Sweating that disrupts daily activities and work
  • Clammy, wet palms making handshakes uncomfortable
  • Foot sweating causing slippery footwear and odour
  • Facial sweating unrelated to physical exertion
  • Sweat dripping from underarms in social situations
  • Need to change clothes multiple times per day
  • Skin maceration or irritation from constant moisture

Prevention Tips for Excessive Sweating

Use clinical-strength antiperspirants containing aluminium chloride

Apply antiperspirant to dry skin in the evening for best absorption

Wear breathable, moisture-wicking fabrics

Choose loose-fitting clothing in dark colours or white

Use absorbent insoles in shoes

Keep stress levels managed through relaxation techniques

Maintain a healthy weight to reduce overall sweating

Avoid known triggers: spicy food, caffeine, alcohol

Lifestyle Advice

In addition to professional treatments, these lifestyle adjustments can help manage excessive sweating:

Keep a sweating diary to identify personal triggers

Carry extra clothing and absorbent wipes for emergencies

Choose shoes made from natural materials that breathe

Practice stress management — mindfulness, deep breathing

Stay hydrated even though it seems counterintuitive

Consider professional treatment if over-the-counter solutions aren't sufficient

Myths vs Facts about Excessive Sweating

Myth

Excessive sweating is just nervousness

Fact

Hyperhidrosis is a medical condition caused by overactive sweat glands. It occurs regardless of emotional state, even during sleep.

Blocking sweat glands is dangerous

Botox treatment only affects the treated area. The body has millions of sweat glands, so overall temperature regulation is not affected.

Sweating more means you're unfit

Hyperhidrosis has nothing to do with fitness level. Fit athletes can have it, and unfit people may not.

There's no real treatment for excessive sweating

Botox injections are clinically proven to reduce sweating by up to 90% for 6-12 months, with an excellent safety profile.

When to Seek Professional Help?

It's important to consult a specialist in time. Book an appointment if you recognise one or more of the following situations:

  • Sweating disrupts your daily work, social life or relationships
  • You avoid certain activities or clothing because of sweating
  • Over-the-counter antiperspirants don't provide adequate relief
  • Sweating starts suddenly or worsens without clear reason
  • You experience night sweats or generalised excessive sweating

Frequently Asked Questions about Excessive Sweating

Find answers to the most common questions about excessive sweating. Have another question? Feel free to contact us.

How does Botox treat excessive sweating?

Botox blocks the acetylcholine neurotransmitter that activates sweat glands. Small injections just below the skin surface in the affected area effectively 'switch off' the sweat glands for 6-12 months.

Is the treatment painful?

We use very fine needles and apply topical anaesthetic cream before the procedure. Most clients describe mild discomfort that lasts only during the injections — about 15-20 minutes total.

How quickly does it work?

Most clients notice a significant reduction in sweating within 3-7 days, with full effect achieved within 2 weeks.

How much does Botox for sweating cost?

Pricing depends on the treatment area and amount of Botox needed. We provide a personalised quote during your free consultation.
