Causes & Solutions for Excessive Sweating (Hyperhidrosis)

Causes & Solutions for Excessive Sweating (Hyperhidrosis)

---

Sweating is a natural function that helps regulate body temperature. But for those who suffer from hyperhidrosis, sweating goes far beyond what is necessary and can become an embarrassing and distressing issue. Excessive sweating can interfere with daily life, stain clothing, and undermine self-confidence — especially in social or professional settings.

At Dermasurge Clinic, we see many patients struggling with the physical and emotional impact of hyperhidrosis. The good news is that modern dermatological treatments offer safe and effective solutions for controlling excessive sweating.

In this article, we explain what causes hyperhidrosis, the different types, and the range of treatment options available at our Harley Street clinic.

What Is Hyperhidrosis?

Hyperhidrosis is a condition characterised by abnormally excessive sweating that’s not necessarily related to heat or exercise. It can affect specific areas — such as the underarms, palms, soles of the feet, or face — or present as generalised sweating across the whole body.

There are two main types of hyperhidrosis:

1. Primary (Focal) Hyperhidrosis

This is the most common form and typically begins in adolescence or early adulthood. It affects localised areas of the body, such as:

• Armpits
  
• Palms
  
• Soles
  
• Forehead

Primary hyperhidrosis is not caused by an underlying health condition. It’s believed to be linked to overactive nerves that trigger sweat glands unnecessarily.

2. Secondary (Generalised) Hyperhidrosis

Secondary hyperhidrosis is less common and is usually caused by an underlying medical condition or medication. It can begin at any age and typically affects the entire body. Causes include:

• Thyroid problems
  
• Diabetes
  
• Menopause
  
• Certain infections
  
• Medications such as antidepressants

For this reason, it’s essential to have your symptoms professionally assessed to determine the root cause.

When to Seek Help

You may want to consider professional treatment for excessive sweating if:

• You need to change clothes several times a day due to wetness
  
• You avoid social situations or certain clothing because of sweat patches
  
• Over-the-counter antiperspirants have no effect
  
• You frequently experience sweaty palms, feet, or underarms even in cool environments

At Dermasurge, we can help you understand what’s causing your symptoms and provide tailored treatment options to manage them effectively.

Effective Treatments for Hyperhidrosis at Dermasurge

Following a consultation with Dr Hiba Injibar, our Consultant Dermatologist, we can recommend a personalised approach to controlling excessive sweating. Our goal is to provide relief and improve your quality of life through safe, evidence-based treatments.

1. Botox® (Botulinum Toxin) Injections

One of the most effective treatments for focal hyperhidrosis is Botox injections, particularly for the underarms, hands, feet, and forehead. Botox works by blocking the nerve signals that stimulate sweat glands, significantly reducing perspiration in the treated area.

Benefits:

• Quick procedure (15–30 minutes)
  
• Results last 4 to 6 months
  
• Minimal downtime
  
• Clinically proven and FDA-approved

Ideal for: Patients with primary focal hyperhidrosis looking for temporary yet highly effective relief.

2. Prescription Topical Treatments

For milder cases, prescription-strength antiperspirants containing aluminium chloride can be helpful. These are stronger than high-street options and work by blocking sweat glands.

Note: These may cause irritation in sensitive skin areas and are generally better suited for underarm use.

3. Oral Medications

In some cases, oral anticholinergic medications may be prescribed to reduce sweating across the body. These work by inhibiting the chemical messengers involved in sweat production.

Side effects such as dry mouth and blurred vision can occur, so these are usually reserved for more severe or generalised sweating that hasn’t responded to other treatments.

4. Investigating Underlying Conditions

For those with secondary hyperhidrosis, the focus will be on identifying and managing the root cause. This may involve:

• Blood tests
  
• Hormone evaluations
  
• Reviewing current medications

Treating the underlying condition often helps resolve or significantly reduce excessive sweating.

Lifestyle Tips for Managing Excessive Sweating

While medical treatments are often the most effective, certain lifestyle adjustments can help manage symptoms day-to-day:

• Wear breathable fabrics like cotton or moisture-wicking materials
  
• Use absorbent pads or dress shields to protect clothing
  
• Avoid spicy foods, caffeine, and alcohol, which can trigger sweating
  
• Keep a diary to identify and avoid personal sweat triggers
  
• Stay cool with fans or air conditioning when possible
