Hyperhidrosis: Causes, Symptoms & Treatment

Hyperhidrosis is a medical condition characterized by excessive sweating that occurs beyond the body’s normal temperature-regulation needs. While sweating is a natural function that helps cool the body, individuals with hyperhidrosis may experience persistent moisture in areas such as the underarms, palms, soles of the feet, or face even without heat or physical exertion.

Dr. Marie Hayag is a board-certified dermatologist specializing in the diagnosis and treatment of excessive sweating conditions. At her Upper East Side dermatology practice in New York City, hyperhidrosis evaluation begins with a physician-led assessment to determine the underlying cause and severity of the condition. Through personalized care plans and evidence-based dermatologic treatments, patients receive safe and effective solutions designed to reduce sweating and improve daily comfort and confidence.

Hyperhidrosis is a condition that causes sweat glands to produce more sweat than the body requires for normal cooling. This excessive sweating can occur in localized areas such as the underarms, hands, feet, or face, or in multiple areas simultaneously.

Approximately 2–3% of the population experiences hyperhidrosis. While the condition is not typically dangerous, it can significantly impact daily activities, clothing choices, social interactions, and overall quality of life.

Because persistent sweating can sometimes be associated with underlying medical conditions, evaluation by a board-certified dermatologist is an important first step toward effective management.

Hyperhidrosis can affect several areas of the body where sweat glands are most active.

• Underarms (axillary hyperhidrosis)
• Palms of the hands (palmar hyperhidrosis)
• Soles of the feet (plantar hyperhidrosis)
• Face and scalp (craniofacial hyperhidrosis)

Excessive sweating in these areas may cause clothing stains, skin irritation, and social discomfort, making medical treatment an important option for many patients.

The primary symptom of hyperhidrosis is excessive sweating that occurs even when the body does not require cooling. Individuals may experience persistent dampness of the skin, visible sweat through clothing, or difficulty keeping hands and feet dry. Sweating may occur daily and often affects specific areas such as the underarms, palms, soles, or face. In some cases, symptoms may interfere with daily activities, social interactions, and personal comfort.

Hyperhidrosis treatment refers to dermatologist-directed therapies designed to reduce sweat production and manage excessive sweating.

These treatments help control overactive sweat glands, reduce moisture in affected areas, and improve daily comfort for individuals experiencing persistent sweating.

Ideal for patients experiencing excessive sweating that does not improve with over-the-counter antiperspirants or lifestyle adjustments.

Botox is an FDA-approved injectable treatment used to temporarily block the nerve signals responsible for activating sweat glands.

Botox significantly reduces sweat production in treated areas, particularly the underarms, by calming overactive sweat glands.

Ideal for patients with moderate to severe hyperhidrosis seeking a non-surgical treatment that can provide several months of sweat reduction.

Dermatologic evaluation for excessive sweating may benefit individuals who:

• Experience persistent sweating without heat or exercise
• Notice excessive moisture in the underarms, hands, or feet
• Have sweating that interferes with daily activities or confidence
• Have not achieved relief using over-the-counter antiperspirants
• Want physician-guided treatment options for hyperhidrosis

Early medical evaluation helps determine whether symptoms are caused by primary hyperhidrosis or another underlying condition.

Hyperhidrosis often presents as visible moisture or dampness on the skin even in comfortable temperatures. Individuals may notice sweat soaking through clothing, difficulty maintaining dry hands, or persistent moisture on the soles of the feet.

Common signs include:

• Frequent underarm sweat stains
• Excessively damp palms
• Moist or slippery feet
• Persistent facial or scalp sweating

Because symptoms may vary in severity, dermatologic assessment helps determine the most effective treatment strategy.
