About Hyperhidrosis

Hyperhidrosis is a medical condition characterized by excessive sweating that goes beyond what's needed to regulate body temperature. Unlike the normal perspiration everyone experiences during exercise or in warm weather, hyperhidrosis causes you to sweat heavily even when you're cool, calm, and at rest.

This condition affects approximately 3% of the population and can significantly impact daily life. Many people with hyperhidrosis experience:

  • Soaked clothing despite using regular antiperspirants
  • Sweaty palms that interfere with handshakes or holding objects
  • Wet feet that can lead to skin problems and discomfort
  • Visible underarm sweat that causes social embarrassment

Two Types of Hyperhidrosis

Hyperhidrosis is classified into two main categories:

Primary Hyperhidrosis typically begins in childhood or adolescence and affects specific areas of the body, most commonly the hands, feet, underarms, and face. This type has no underlying medical cause and often runs in families, suggesting a genetic component.

Secondary Hyperhidrosis develops later in life and is usually caused by an underlying health condition or medication. Unlike primary hyperhidrosis, it tends to cause sweating across the entire body and may occur during sleep.

Understanding which type of hyperhidrosis you have is essential for determining the most effective treatment approach. Our dermatologists can evaluate your symptoms and develop a personalized treatment plan to help you manage excessive sweating.

Diagnosing Hyperhidrosis

Determining the cause of excessive sweating involves a comprehensive evaluation to rule out other medical conditions and identify the most appropriate treatment approach. Our dermatologists use several diagnostic methods:

Medical History and Physical Examination – We'll discuss when your symptoms began, which areas are affected, and how sweating impacts your daily life. Understanding your family history and any medications you take helps us determine whether you have primary or secondary hyperhidrosis.

Specialized Sweat Tests – Advanced diagnostic tools help us measure sweat production under controlled conditions:

  • Starch-Iodine Test – An iodine solution is applied to the affected area, followed by starch. Areas of excessive sweating turn dark blue, clearly showing the pattern and severity.
  • Thermoregulatory Sweat Test (TST) – This test evaluates sweat distribution across your entire body, helping identify nerve pathway issues.

These tests provide precise results that guide our treatment recommendations and ensure an accurate diagnosis.

How We Help with Excessive Sweating

Diagnosis

We assess to see the type and severity of your condition to recommend the most effective treatment.

Treatment

Our team will create a personalized treatment plan based on your specific symptoms, lifestyle, and goals to help you achieve lasting relief from excessive sweating.

Treatment Options

We offer a range of effective treatments for hyperhidrosis, from conservative approaches to more advanced interventions. Your treatment plan will be tailored to the severity of your condition and your lifestyle needs.

Non-Surgical Treatments

Prescription-Strength Antiperspirants – Clinical-strength antiperspirants containing aluminum chloride hexahydrate are often the first line of treatment. These work by blocking sweat ducts and can significantly reduce perspiration when applied correctly.

Botox Injections – FDA-approved for excessive underarm sweating, Botox temporarily blocks the nerves that trigger sweat glands. Results typically last 4-6 months, and treatments can be repeated as needed. This option is also effective for hands, feet, and facial sweating.

Iontophoresis – This non-invasive treatment uses a mild electrical current passed through water to temporarily disable sweat glands. It's particularly effective for hands and feet and requires regular maintenance sessions.

Oral Medications – Prescription medications called anticholinergics can reduce sweating throughout the body by preventing stimulation of sweat glands.

Lifestyle Modifications – We'll work with you on practical strategies including:

  • Stress management techniques like yoga and meditation
  • Dietary adjustments to avoid sweat triggers (spicy foods, caffeine)
  • Clothing choices such as breathable fabrics and moisture-wicking materials

Advanced Treatment Options

Surgical Interventions – For severe cases that don't respond to other treatments, surgical options like endoscopic thoracic sympathectomy (ETS) may be considered. This procedure interrupts the nerve signals that trigger excessive sweating and offers a more permanent solution.

Emerging Therapies – We stay current with the latest advances in hyperhidrosis treatment, including newer technologies and alternative approaches that may benefit certain patients.

Frequently Asked Questions

Can hyperhidrosis be cured completely or only managed?

Hyperhidrosis, influenced by genetic factors, can be managed through various methods. Surgical options offer potential long-term control, while alternative therapies may provide temporary relief. However, a complete cure is currently not guaranteed in all cases.

How does hyperhidrosis impact a person's mental health?

Hyperhidrosis often exacerbates social anxiety and self-esteem issues due to persistent excessive sweating. The constant need for coping mechanisms can lead to stress, negatively affecting mental health and overall quality of life.

Can lifestyle changes help reduce symptoms of hyperhidrosis?

Indeed, lifestyle changes can influence hyperhidrosis symptoms. Dietary modifications may reduce sweat production, while stress management techniques can control anxiety-induced sweating. Regular exercise might also contribute to a healthier sweat response.

Are there any new treatments or research studies on hyperhidrosis?

Current research on hyperhidrosis is exploring several avenues, including the role of genetics in disease development, potential medication side effects, and new surgical approaches for treatment. Continued studies are critical to advancing therapeutic strategies.

How does living in different climates affect hyperhidrosis symptoms?

Climate adaptation influences hyperhidrosis symptoms, with warmer climates potentially exacerbating sweat triggers. Seasonal variations also play a role; increased heat and humidity can intensify symptoms, while cooler conditions may alleviate them.
