How to Tell If You Have Hyperhidrosis (and What to Do About It)

Excessive sweating isn’t just uncomfortable; it can also interfere with your daily life, affect your confidence, and make even routine activities stressful. While everyone sweats, some people sweat far more than is needed to regulate body temperature. This condition is called hyperhidrosis, and it’s more common than you might think. 

If you’ve ever wondered “How to tell if you have hyperhidrosis?” this guide breaks down the symptoms, causes, and treatment options to help you understand when it’s time to see a dermatology specialist.

What Is Hyperhidrosis?

Hyperhidrosis is a medical condition characterized by excessive sweating that goes beyond the body’s natural need to cool itself. Unlike sweating during exercise or on a hot day, hyperhidrosis often happens unpredictably, even in cool environments or while resting.

Dermatology specialists classify hyperhidrosis into two main types:

  • Primary hyperhidrosis: Excessive sweating that isn’t linked to another medical condition. It usually starts in childhood or adolescence and tends to affect specific areas like the underarms, palms, soles of the feet, or face.
  • Secondary hyperhidrosis: Sweating that develops later in life as a side effect of another health condition or medication. This type is usually more generalized, affecting larger areas of the body.

Common Symptoms of Hyperhidrosis

Wondering how to tell if you have hyperhidrosis? Look for these signs:

  • Excessive sweating in specific areas such as the underarms, palms, feet, or face.
  • Sweating that soaks through clothing even when you’re not hot or exercising.
  • Sweaty hands or feet that make it difficult to grip objects, shake hands, or wear certain shoes.
  • Visible sweat beads on your skin when you’re at rest.
  • Skin changes such as peeling, maceration, or recurring infections in sweaty areas.
  • Disruption to daily life, work, or social activities because of sweating.

If your sweating feels out of proportion to your environment or activity level, it may be more than just a normal response; it could be hyperhidrosis.

What Causes Hyperhidrosis?

The causes vary depending on whether it’s primary or secondary hyperhidrosis.

Primary Hyperhidrosis

This type is thought to be related to overactive sweat glands controlled by the nervous system. While the exact cause isn’t fully understood, research suggests genetics may play a role since it often runs in families.

Secondary Hyperhidrosis

This type is linked to underlying medical issues or triggers, including:

  • Endocrine conditions such as diabetes or thyroid disorders
  • Menopause and hormonal changes
  • Infections
  • Neurological conditions
  • Medications, including antidepressants or certain pain relievers

If sweating starts suddenly in adulthood, is widespread, or occurs at night, it may be a sign of secondary hyperhidrosis, and it’s important to seek medical care to rule out other health conditions.

How to Tell If You Have Hyperhidrosis vs. Normal Sweating

Because sweating is a natural body function, it can be tricky to determine what’s “too much.” Here are some distinctions:

  • Timing: Normal sweating happens with heat, stress, or exertion. Hyperhidrosis can occur at random times, often without a clear trigger.
  • Amount: Soaking through clothes or dripping sweat while sitting still is not typical.
  • Impact: If sweating regularly disrupts work, school, relationships, or self-esteem, it points toward hyperhidrosis.
  • Location: Hyperhidrosis often affects specific, symmetrical areas (both hands, both feet, both underarms).

How Is Hyperhidrosis Diagnosed?

A dermatology provider can usually diagnose hyperhidrosis based on your symptoms and medical history. In some cases, they may recommend tests such as:

  • Starch-iodine test: A powder and iodine solution highlight areas of heavy sweating.
  • Gravimetric test: Measures the actual amount of sweat produced.
  • Blood tests or imaging: To rule out secondary causes.

Diagnosis is important because it helps guide the most effective treatment plan.

Treatment Options for Hyperhidrosis

The good news is that effective treatments are available. Depending on the severity and location of your sweating, a dermatologist may recommend:

  • Prescription-strength antiperspirants: Stronger than over-the-counter products, these help block sweat glands.
  • Certain medications can temporarily reduce sweating by blocking signals to the sweat glands.
  • Botox® injections: FDA-approved for underarm hyperhidrosis, Botox works by temporarily blocking the nerves that trigger sweating. Results typically last several months.
  • Iontophoresis: A device delivers a mild electrical current through water to reduce sweating in the hands and feet.
  • Laser or microwave-based treatments: These destroy overactive sweat glands for longer-lasting relief.
  • Endoscopic thoracic sympathectomy (ETS): Reserved for severe cases, this procedure interrupts the nerves that cause sweating.

Living With Hyperhidrosis

Hyperhidrosis can be frustrating, but with treatment, many people see significant improvements in both symptoms and quality of life. In addition to medical care, small lifestyle adjustments may also help:

  • Wear lightweight, breathable fabrics
  • Carry extra clothing or absorbent pads if needed
  • Use moisture-wicking socks and change shoes frequently
  • Practice stress management techniques, since anxiety can worsen sweating

When to See a Dermatologist

If you’ve tried to manage excessive sweating on your own without success, or if your symptoms started suddenly and severely, it’s time to consult a dermatology provider. They can determine whether your sweating is normal, related to hyperhidrosis, or connected to another medical condition.
