Causes, Symptoms & Treatment Options
by Dr. Janna M. Bentley
Excessive sweating, also known as hyperhidrosis, is a common condition that affects millions of people and can have a significant impact on everyday life. For some, it may mean constantly changing clothing, avoiding certain social situations, struggling with hand sweating at work, or feeling self-conscious in professional or personal settings.
While many people associate neuromodulator injections with cosmetic treatments, these medications are rooted in medical use, including the treatment of excessive sweating. The good news is that hyperhidrosis is treatable, and there are several medical options available depending on the area affected and severity of symptoms.
At Lakeshore Vein & Aesthetics Clinic in Kelowna, treatment begins with a thorough consultation and assessment to better understand the type of sweating involved and which treatment options, if any, may be most appropriate.
What Is Hyperhidrosis?
Hyperhidrosis refers to sweating beyond what the body needs for normal temperature regulation. While sweating is a natural and important function, excessive sweating that interferes with daily activities may indicate hyperhidrosis. This condition affects nearly 3% of the population and often goes undiagnosed or untreated despite its impact on quality of life.
Symptoms can range from mild to severe and may affect:
- Social confidence
- Clothing choices
- Work environments
- Exercise and recreation
- Daily comfort
Localized vs Generalized Hyperhidrosis
Hyperhidrosis is generally divided into two categories.
Localized Hyperhidrosis
Localized hyperhidrosis occurs in otherwise healthy individuals and typically affects specific areas of the body, most commonly:
- Underarms
- Hands
- Feet
- Face
It often occurs symmetrically on both sides of the body and may be triggered by emotional stress, anxiety, heat, caffeine, spicy foods, or exercise. This form of hyperhidrosis commonly begins in childhood or adolescence.
Generalized Hyperhidrosis
Generalized hyperhidrosis affects larger areas or the entire body and may be associated with underlying medical conditions such as hormonal disorders, infections, or other systemic health concerns.
In these cases, a more extensive medical evaluation may be recommended.
What Causes Excessive Sweating?
The exact cause of localized hyperhidrosis is not fully understood, but it is believed to involve overactivity of the autonomic nervous system, which helps regulate body temperature and sweating.
In people with hyperhidrosis, the sweat glands themselves are normal, but the body may produce an exaggerated sweating response to triggers such as heat, stress, or emotion. There also appears to be a genetic component, as many individuals with hyperhidrosis report a family history of excessive sweating.
It is important to understand that hyperhidrosis is not caused by poor hygiene and often occurs even when the body does not need cooling.
Treatment Options for Hyperhidrosis
Treatment depends on the severity of symptoms and which areas of the body are affected.
Medical-Grade Antiperspirants
The first line of treatment is often prescription-strength antiperspirants containing higher concentrations of aluminum salts than standard over-the-counter products.
These products work by helping block sweat ducts and may be effective for mild to moderate underarm sweating. Higher concentrations may also be used for hands and feet in some cases.
Medical Neuromodulator Injections for Excessive Sweating
Medical neuromodulator injections have become one of the most common and effective treatments for localized hyperhidrosis, particularly for underarm sweating.
These treatments work by temporarily blocking the nerve signals responsible for activating sweat glands. Treatment is performed in clinic using a series of small injections in the affected area. Many patients begin noticing improvement within days, and results may last several months before repeat treatment is needed.
Neuromodulator treatments may also be used for excessive sweating of the hands and feet, although these areas can be more sensitive and may require additional comfort measures during treatment. While many people associate these treatments with cosmetic injections, they also have several established medical applications.

Iontophoresis
Iontophoresis is commonly used for sweating of the hands and feet. This treatment involves placing the hands or feet in shallow water while a mild electrical current passes through the area. While the exact mechanism is not fully understood, the treatment may help reduce sweat gland activity over time. Multiple sessions are typically required, and maintenance treatments are often needed.
Surgical Treatment
Surgical treatment is generally considered only when other treatments have not been successful. Procedures such as endoscopic thoracic sympathectomy may be effective in some cases but can carry additional risks and potential complications. Surgical options are typically reserved for more severe cases of hyperhidrosis.
Who May Benefit From Treatment?
You may benefit from a medical assessment if you have excessive sweating, here are a few examples:
- Soaks through clothing regularly
- Interferes with work or social situations
- Affects your hands, feet, or grip
- Causes discomfort during everyday activities
- Continues despite regular antiperspirant use
Because sweating patterns and causes vary from person to person, treatment recommendations should be individualized.
