What is Hyperhidrosis (Excessive Sweating)?

Hyperhidrosis is a medical condition characterised by excessive, uncontrollable sweating that can affect specific areas such as the underarms (axillary hyperhidrosis), palms (palmar hyperhidrosis), soles of the feet (plantar hyperhidrosis), or the entire body (generalised hyperhidrosis). It typically begins during adolescence and commonly affects the underarms, hands, and feet.

While hyperhidrosis is not life-threatening, it may impact an individual’s quality of life—causing discomfort, clothing changes, and potential skin irritation. Some individuals may also experience social and emotional stress related to the condition.

Recognising Symptoms of Hyperhidrosis

Common signs of hyperhidrosis include:

• Persistent wetness or clamminess in the hands, feet, or underarms
• Noticeable sweating during the day, even in cool conditions
• Avoidance of physical contact due to wet palms
• Skin changes or irritation from moisture buildup
• The need to change clothing frequently due to sweat

What Causes Hyperhidrosis?

In some individuals, excessive sweating occurs without any underlying medical condition (primary hyperhidrosis), and may have a genetic component. Others may develop it as a result of medications, infections, or endocrine conditions (secondary hyperhidrosis). Contrary to early beliefs, anxiety is often a result, not a cause, of excessive sweating.

Available Treatment Options

For individuals whose symptoms do not improve with topical or lifestyle measures, non-surgical treatment options may be considered.

Neurotoxin-Based Injectable Therapy

In certain cases, neurotoxin-based injectables can be administered to areas such as the underarms to help regulate sweat gland activity. These injectables are designed to temporarily reduce the signals that activate sweat production.

Treatment process:

• The area is cleansed and a numbing cream may be applied for comfort.
• A series of small injections are administered into the affected area.
• The procedure typically takes around 10–20 minutes, excluding preparation time.

Commonly treated areas:

• Underarms (axillary hyperhidrosis)

For areas such as the palms or soles, other treatment options may be discussed with your doctor depending on your pain tolerance, skin sensitivity, and goals.

What to Expect After Treatment

Most patients are able to resume daily activities soon after treatment. As with any medical procedure, individual results and duration of effect can vary. During your consultation, a licensed medical practitioner will discuss your symptoms, treatment suitability, and possible outcomes.
