Excessive Sweating Hyperhidrosis

Excessive Sweating Hyperhidrosis

Sweating is the body’s natural way of cooling down. It keeps our temperature in check and flushes out toxins. But when sweating goes far beyond what’s needed for temperature control—drenching clothes, soaking palms, or causing embarrassment in daily life—it’s called hyperhidrosis.

This condition affects millions worldwide, often starting in adolescence, and though it’s not life-threatening, it can deeply affect confidence, work, and social life.

What Exactly Is Hyperhidrosis?

Hyperhidrosis means sweating more than the body needs to regulate temperature. It can happen even when it’s cool outside or when you’re at rest. Sweat glands become overactive, producing far more perspiration than necessary.

Primary focal hyperhidrosis:

This type isn’t caused by another medical issue. It usually affects specific areas like the palms, soles, underarms, or face. Genetics often play a role, meaning it can run in families.

Secondary generalised hyperhidrosis

This type results from an underlying condition such as diabetes, thyroid disorders, menopause, infections, or even certain medications. It usually causes excessive sweating all over the body, not just in one area.

Common Signs and Symptoms

Constant dampness on the hands, feet, underarms, or face

Visible sweat marks on clothes, even in mild weather

Clammy skin or peeling due to

Frequent need to change clothes or use towels

Skin irritation, odour, or fungal infections due to trapped moisture

Emotional distress or anxiety related to sweating episodes

Many people notice symptoms intensify under stress, pressure, or anxiety, creating a frustrating loop—stress causes sweating, and sweating causes more stress.

What Causes Hyperhidrosis?

In primary hyperhidrosis, the problem lies in the overactivity of the sympathetic nervous system—the part that controls involuntary actions like sweating. These nerves signal the sweat glands too often, even without heat or exercise.

In secondary hyperhidrosis, triggers can include:

Hormonal changes (like menopause or puberty)

Low blood sugar or diabetes

Thyroid imbalances (especially hyperthyroidism)

Neurological issues (like Parkinson’s or spinal cord injury)

Certain medications (antidepressants, opioids, painkillers)

Infections or chronic illnesses

How It Affects Daily Life

The physical discomfort is only part of the story. Hyperhidrosis often takes a psychological toll—people avoid shaking hands, socialising, or wearing light-colored clothes. Students may struggle to hold pens, while professionals might feel embarrassed during meetings.

Over time, this can lead to social withdrawal, anxiety, and low self-esteem. Many people live with the condition for years before seeking help, not realising that effective treatments exist.

Diagnosis

Diagnosis usually starts with a doctor reviewing your medical history and symptoms. They may ask when the sweating occurs—day or night, specific areas or all over.

Tests like the starch-iodine test (which highlights sweaty areas) or a sweat rate test help measure how much perspiration your body produces. Blood tests can also help rule out underlying conditions like thyroid or glucose imbalances.

Treatment Options

Treatment depends on severity and the underlying cause.

Antiperspirants (with aluminium chloride)

Over-the-counter or prescription-strength products can block sweat glands temporarily. They’re often the first line of treatment.

Medications

Oral anticholinergics like glycopyrrolate or oxybutynin reduce sweating but may cause dry mouth or blurred vision.

Botox Injections

Botulinum toxin injections block nerve signals that trigger sweating. Results last for 6–9 months and work particularly well for underarms and palms.

Lontophoresis

A mild electrical current is passed through water to temporarily block sweat glands, mainly used for hands and feet.

Microwave or Laser Therapy

These modern techniques target and destroy sweat glands with controlled heat—effective but costly.

Surgery (sympathectomy)

Reserved for severe cases, this procedure involves cutting or clamping the overactive nerves that cause excessive sweating. It’s a last resort due to potential side effects, such as compensatory sweating elsewhere on the body.

Lifestyle and Home Remedies

Wear breathable, natural fabrics like cotton or linen.

Bathe daily and use antibacterial soap to reduce odour.

Stay hydrated to balance body temperature.

Manage stress through yoga, meditation, or deep breathing.

Avoid caffeine, spicy foods, and alcohol, which can trigger sweating.

When to See a Doctor

If excessive sweating interferes with your daily activities, causes emotional distress, or suddenly begins without an obvious cause, it’s time to consult a dermatologist or physician. Early treatment can prevent complications and restore normalcy to your routine.

Final Thoughts

Excessive sweating might seem like a minor issue, but for those living with hyperhidrosis, it can feel overwhelming. The good news is—treatments today are far more effective, discreet, and accessible than ever before. Whether it’s a topical solution, a medical procedure, or lifestyle adjustments, the right approach can help you stay dry, confident, and comfortable in your own skin.
