Dr. Szerman explains hyperhidrosis:

What Is Hyperhidrosis?


According to the Brazilian Society of Dermatology, hyperhidrosis is a disease characterized by excessive sweating caused by hyperactivity of the sweat glands, which is often caused by no apparent cause. This condition affects 1 to 5% of the population and has a genetic or pathological cause.

The disease affects various parts of the body, with the armpits, palms of the hands, soles of the feet, face, groin, and scalp being the most commonly affected.

People with hyperhidrosis sweat excessively under normal conditions and even more so in hot weather or under stress.

Hyperhidrosis can be an uncomfortable condition, affecting both men and women’s social and professional lives. Excessive sweat on the armpits can stain clothes, and sweat on the hands can reduce the ability to handle objects and be embarrassing.

Not to mention that hyperhidrosis can cause other skin ailments, like warts, eczema, dermatitis, folliculitis, nail fungus, athlete’s foot, and more.

Therefore, finding ways to treat hyperhidrosis is critical so that its progression does not disrupt your personal, social, or even professional life.

What Types of Hyperhidrosis Exist?

Hyperhidrosis is classified according to the cause into two types: primary and secondary.

Primary Focal Hyperhidrosis

Primary hyperhidrosis often begins in childhood due to a genetic predisposition, which causes excessive sweating in the feet, hands, and armpits. Less often, this type may also affect the face or scalp.

Almost 50% of all individuals with hyperhidrosis have a family history of the condition, suggesting genetics may be a contributing factor.

Secondary Generalized Hyperhidrosis

Secondary Hyperhidrosis (also known as Diffuse or Generalized Hyperhidrosis) can be caused by external factors and affect multiple body areas at any time.

Hyperhidrosis may be caused by external factors and diseases, such as lymphomas, diabetes, medication use, alcoholism, anxiety disorders, neoplasms, menopause, infections, heart diseases, fevers, or hormonal changes.

How Can You Tell if You Have Hyperhidrosis?

As previously stated, excessive sweating, known as thermoregulation, is a natural process the body uses to regulate its temperature. However, one should take notice when the sweat production is excessive.

If you experience excessive sweating in unlikely conditions, like cold temperatures or when you’re not active, see a doctor to get a diagnosis and the best treatment for your hyperhidrosis.

Symptoms of Hyperhidrosis

Hyperhidrosis treatments are highly effective and improve a patient’s quality of life. Here are some of the available treatments:

Botox Injections

Botox injections are widely considered the gold standard for treating hyperhidrosis.

This hyperhidrosis treatment uses a bacterium substance known as Clostridium Botulinum to inhibit excessive sweating.

The substance reduces muscle tension and suppresses sweat production for 3-10 months when applied to regions with a high concentration of sweat glands.

Botox injections are typically used to treat hyperhidrosis. Usually, the areas injected are the hands, feet, and armpits, but this may vary depending on the doctor’s recommendation.

The procedure is quick and easy, and should be repeated every 6 months for optimum results. It is a highly effective treatment, especially for severe cases, with great outcomes.

Botulinum toxin is an effective treatment for hyperhidrosis which offers several advantages over other treatments, including:

  • The application process is swift.
  • It’s painless
  • No anesthesia is required.
  • It is a cost-effective procedure.
  • It is 100% effective in reducing excessive sweating.
  • Results may last up to ten months without maintenance.
  • Regular maintenance every six months ensures long-lasting results.
  • Botulinum toxin is harmless to the organism.
  • It eliminates the need for daily tasks such as taking medications, grooming, and applying antiperspirants.
  • This procedure is not invasive.
  • No rest period after applying required.
  • Hyperhidrosis is best treated with this method.
  • It visibly improves skin in the area of application.
  • It helps reduce signs of aging on the skin.

Laser Treatment

Laser treatment is an alternative for Hyperhidrosis. This technique uses light energy to reduce sweat gland size, thus decreasing their production of sweat.

Use of Antiperspirants

Antiperspirants are a popular treatment for hyperhidrosis. They are products that can be applied to the skin to prevent sweating. They typically contain aluminum salts which temporarily block sweat glands in the skin, reducing the amount of sweat that is released, as well as body odor.

Antiperspirant active ingredients are absorbed by the skin, forming a protective barrier to reduce sweat secretion.

Use of Specific Medications

Hyperhidrosis can be treated with long-term use of medication prescribed by a doctor.

These drugs inhibit the stimulation of the sweat glands, decreasing perspiration greatly. However, they may cause decreases in urine, saliva and tears production, so caution should be taken.

Endoscopic Thoracic Sympathectomy Surgery

Thoracic Sympathectomy, a surgery performed by a thoracic surgeon, is an option for severe cases of hyperhidrosis that have not responded to other treatments. It works by blocking certain functions of the sympathetic nervous system.

Sweat production is suppressed and can be treated on the face, neck, scalp, chest, abdomen, armpits, back, hands, and feet.

A thoracoscope – an instrument with a camera attached – is inserted through one side of the thorax to reach the sympathetic nerve close to the spinal cord. This surgical procedure is performed via video.

The surgeon will decide whether to divide the nerve or clip it into pieces to reduce sweat gland activity.

The procedure, which lasts approximately one hour, requires general anesthesia and two weeks of rest post-surgery.

Sweat Gland Removal Surgery

For more severe cases that have not responded to other treatments, surgeons may remove sweat glands to reduce excessive sweating in the armpits.

Under local anesthesia, two small cuts in the armpits are made, and hydrosuction cannulas inserted to remove the sweat glands. Post-operatively, patients must rest for two days and avoid straining the arms.

What Is the Most Effective Treatment for Hyperhidrosis?

Botulinum toxin is the most commonly used treatment for hyperhidrosis. It’s a non-surgical procedure that addresses the root of the problem efficiently, quickly, and safely.


What Body Areas Are Most Commonly Affected by Hyperhidrosis?

Primary and secondary hyperhidrosis most frequently affect the palms of the hands, armpits, groin, and soles of the feet. Excessive sweating of the face, scalp, breasts, and other areas of the body is, however, also common.

What Is the Duration of Hyperhidrosis Treatment?

Treatment lengths vary depending on the treatment chosen and the doctor’s recommendation. Botulinum toxin treatment requires maintenance every six months and gradually reduces sweat production, decreasing the need for further applications. Times may vary for other treatments.

How Many Sessions Are Necessary?

The duration and number of treatment sessions vary based on severity, region, procedure, and other factors. Botulinum toxin treatments last up to 10 months and require a second session after 6 months to maintain results.

What Is the Title of a Doctor Who Specializes in Treating Hyperhidrosis?

Different medical specialties treat hyperhidrosis, depending on the diagnosis, origin, and treatment goals. Considering intensity of disease, its location, and treatment options, which can include botulinum toxin, local medication, or even surgery.
