Hyperhidrosis (Excessive Sweating)

About Hyperhidrosis

Hyperhidrosis is a condition characterised by abnormally excessive sweating that’s not necessarily related to heat or exercise. Sweating can affect just one specific area or the entire body, though it commonly targets palms, feet, underarms, and the face. This can happen without obvious triggers, although factors such as stress, anxiety, certain foods, and medications can contribute to it.

While the exact cause of primary hyperhidrosis is unknown, it is thought to be associated with overactivity of the sympathetic nervous system and can be hereditary. Secondary hyperhidrosis, on the other hand, is often linked to underlying health conditions like diabetes, thyroid problems, and certain infections, or it may be a side effect of medications.

Hyperhidrosis can significantly impact daily life, causing both physical discomfort and emotional distress. Excessive sweating might lead to skin infections, social embarrassment, and could change the way people conduct their daily activities due to the concern of visible sweating.

Symptoms

Symptoms of hyperhidrosis can vary, but typically include:

• Visible sweating, even without physical exertion or elevated temperature, sometimes resulting in soaked clothing or sweat dripping onto objects.
• Sweating that disrupts everyday activities, such as holding a pen or using electronic devices.
• Soft, white, and peeling skin in areas of constant wetness.
• Skin infections in areas that sweat excessively, like athlete’s foot or jock itch, due to the moist environment.

This condition often starts in childhood or adolescence and doesn’t necessarily indicate an underlying medical issue. Excessive sweating typically affects focal areas of the body such as underarms, hands, feet, and forehead, and usually occurs on both sides of the body symmetrically. It can be more pronounced during situations that evoke strong emotions like stress or anxiety.

Understanding your triggers and how your body responds to different situations can be helpful in managing hyperhidrosis effectively. If you’re experiencing these symptoms, it’s important to consult with a healthcare provider to explore potential treatment options and strategies for managing the condition.

Diagnosis

The diagnosis of hyperhidrosis typically involves a combination of a physical examination and a review of the patient’s medical history. During the examination, the healthcare provider may look closely at the areas of the body that sweat excessively. Specific questions may be asked to understand the nature and extent of the sweating.

In some cases, a sweat test, known as the Minor test, may be conducted. This test involves applying an iodine solution to the affected area, followed by sprinkling starch over the iodine solution. Areas of excessive sweating will turn dark blue, indicating the presence of hyperhidrosis.

If secondary hyperhidrosis is suspected, where the excessive sweating is due to an underlying medical condition, additional tests may be necessary.

Treatments

Over-the-counter options offer a strategic approach to managing hyperhidrosis, providing solutions for those experiencing excessive sweating. Products available include advanced formulations with higher concentrations of active ingredients like aluminium chloride and aluminium zirconium than regular antiperspirants. These compounds help decrease sweating by blocking sweat gland ducts.

For individuals with more intensive sweating concerns, “clinical strength” products are available, featuring familiar and specialised brands. These products are most effective when applied to dry skin and are recommended for use at night, allowing the antiperspirants to work optimally.

Here are some products highlighted from our online pharmacy:

• Anhydrol Forte Roll-on (60ml): Containing a strong active ingredient, Chloride Hexahydrate, this product is used for treating excessive sweating.
• Driclor Antiperspirant Roll-on (75ml): Offers protection against heavy perspiration and is long-lasting, effective for days, not just hours.
• Perspirex Antiperspirant Roll-On Original (20ml): This roll-on minimises sweat production and can last for 3-5 days with a low risk of skin irritation.
• Perspirex Antiperspirant Roll-On Strong (20ml):

Designed for more intense cases, this version minimises sweat production effectively and has a lasting duration of up to 5 days.

Prevention Strategies

To help prevent hyperhidrosis, there are several steps that you can follow:

Use an antiperspirant rather than just a deodorant. Antiperspirants contain aluminium salts that help reduce sweating.

Apply antiperspirant to dry skin before bedtime to increase its effectiveness.

Maintain a sweat journal to identify and avoid your sweat triggers, which can include heat, anxiety, or specific foods like those with MSG or caffeine.

For a more personalised approach and additional tips, consider seeing a board-certified dermatologist who can offer tailored advice and potential prescription options. Remember, lifestyle adjustments like choosing breathable fabrics and staying hydrated can also contribute to managing symptoms.
