Axillary hyperhidrosis is a condition characterised by excessive sweating in the underarm area, beyond what the body needs to regulate temperature. It can interfere with daily activities, cause embarrassment, and lead to social or occupational difficulties. While not life-threatening, it can significantly impact a person’s quality of life.
Axillary hyperhidrosis is classified into two main types:
- Primary Axillary Hyperhidrosis
- Caused by overactive sweat glands with no underlying medical condition.
- Often starts in adolescence or early adulthood and may have a genetic component.
- Secondary Hyperhidrosis
- Results from an underlying medical condition or external factors such as medications, hormonal changes, or infections.
- Less common for isolated underarm sweating.
Causes of axillary hyperhidrosis:
Primary Axillary Hyperhidrosis:
- Overactivity of the eccrine sweat glands, driven by overstimulation from the sympathetic nervous system, that can be triggered by:
- Emotional stress or anxiety
- Heat or physical exertion
- Consumption of certain foods or beverages, such as caffeine or spicy foods.
- Genetic predisposition is suspected in many cases.
Secondary Axillary Hyperhidrosis:
- Hormonal changes (e.g., menopause, hyperthyroidism)
- Neurological disorders
- Certain medications (e.g., antidepressants)
- Infections or metabolic conditions
These range from conservative to advanced interventions:
A variety of treatment options are available to manage axillary hyperhidrosis effectively.
Topical Treatments
- Antiperspirants: Over the counter or prescription-strength products containing aluminium chloride to block sweat glands.
- Sweat Pads or Shields: Absorbent pads placed under clothing to manage visible sweating.
Oral Medications
- Anticholinergics: Medications like glycopyrrolate can reduce sweat production, though they may have side effects such as dry mouth or blurred vision.
Iontophoresis
A non-invasive treatment that uses low electrical currents to reduce sweat production:
How It Works:
- Patients place their hands, feet, or underarms in water, or use wet pads connected to a device that delivers a mild electrical current.
- Typically requires 3–5 sessions per week initially, followed by maintenance sessions as needed.
Benefits:
- Safe and effective for many patients.
- Non-invasive and free of systemic side effects.
Botulinum Toxin Injections
- Temporarily blocks the nerves that signal sweat glands to produce sweat.
- Results last 6–12 months and can be repeated as needed.
Radio Frequency (RF) Micro Needling
Targets skin glands to reduce size and activity (CANDELA MATRIX).
Microwave Energy Treatment (not available at KDAA)
- Uses microwave energy to destroy sweat glands in the underarms permanently.
- Requires minimal downtime with long-lasting results.
Surgical Options
- Endoscopic Thoracic Sympathectomy (ETS): A surgical procedure to cut or clamp the nerves that stimulate sweat glands.
- Reserved for severe, treatment-resistant cases due to potential side effects like compensatory sweating.
Lifestyle Tips to Manage Axillary Hyperhidrosis:
- Wear lightweight, breathable clothing made from natural fibres.
- Avoid triggers such as caffeine, spicy foods, and emotional stress.
- Practice good underarm hygiene to reduce irritation and odour.
