Understanding Axillary Hyperhidrosis: Causes, Symptoms, and Treatment Options

By: Our Team



Sweating is a natural bodily function that helps regulate body temperature and expel toxins. However, for some individuals, sweating can become an overwhelming and embarrassing problem, particularly in the underarm region. This condition is known as axillary hyperhidrosis, and it can have a significant impact on a person's quality of life. At OneSkin Integrative Dermatology in Chambersburg, PA, we explore the causes, symptoms, and treatment options for axillary hyperhidrosis to help those affected by this condition find relief and regain their confidence.

What is Axillary Hyperhidrosis?

Axillary hyperhidrosis is a medical condition characterized by excessive and uncontrollable sweating in the underarm area. While sweating is a normal response to heat, physical exertion, or stress, individuals with axillary hyperhidrosis experience profuse sweating even in the absence of these triggers. This condition can lead to social anxiety, discomfort, and embarrassment, making it challenging to engage in everyday activities and interact with others.

Causes of Axillary Hyperhidrosis

The exact cause of excessive underarm swearing is not fully understood, but it is believed to be related to an overactive sympathetic nervous system. This system controls sweating, and in some individuals it becomes overstimulated, leading to excessive perspiration. Genetics may also play a role, as the condition often runs in families. 

Symptoms of Axillary Hyperhidrosis

1. Excessive Sweating: The hallmark symptom of axillary hyperhidrosis is profuse, continuous sweating in the underarm area, which can soak through clothing.

2. Frequent Clothing Changes: Sufferers often need to change their clothes multiple times a day to stay dry and comfortable.

3. Body Odor: The constant moisture in the underarms can lead to the development of an unpleasant body odor.

4. Skin Irritation: Constant moisture and friction can result in skin irritation, rashes, and even fungal infections in the affected area.

5. Social Anxiety: Many individuals with axillary hyperhidrosis experience anxiety and embarrassment in social situations, leading to reduced self-esteem and quality of life.

Treatment Options

The good news is that there are several treatment options available to help manage and alleviate the symptoms of axillary hyperhidrosis! At OneSkin Integreative Dermatology in Chambersburg, PA, we have the safest, most effective treatment options for our patients. 

1. Antiperspirants: Over-the-counter or prescription-strength antiperspirants containing aluminum chloride can help reduce sweating. Applying them at night before bed and washing off in the morning is a common routine.

2. Botox Injections: Botox injections can effectively block the release of chemicals that trigger sweat production. The effects typically last for several months.

3. Medications: Certain oral medications like anticholinergics may be prescribed to reduce sweating, but they can have side effects and are not suitable for everyone.

4. Thermolysis: A relatively new and minimally invasive treatment, thermolysis uses heat energy to selectively target and eliminate sweat glands.

We are now offering Brella 3-minute SweatControl Patch at OneSkin, which works via targeted alkali thermolysis! 

Brella takes minutes to do in a comfortable office setting and reduces sweat production by >75% for 3-4 months.  Ready to take control of your excessive sweating? Schedule a consultation today!
