Understanding Hyperhidrosis: Causes and Symptoms

The dermatologists at Cary Dermatology Center in Cary, NC, offer comprehensive dermatology services, including diagnosis and treatment of hyperhidrosis. 

What You Need to Know About Hyperhidrosis 

Hyperhidrosis is classified as primary or secondary hyperhidrosis. Primary hyperhidrosis is believed to be caused by a problem with the part of the nervous system that controls sweating. Genetics may also be a factor. Secondary hyperhidrosis is caused by an underlying condition or issue, which may include: 

• Medications, including some pain relievers, antidepressants, and insulin 
• Infection due to a virus, bacteria, or fungus 
• Diabetes, hyperthyroidism, Parkinson's disease, or other neurological conditions
• Menopause, pregnancy, hypoglycemia, or anxiety 

You may have hyperhidrosis if you notice: 

• Excessive sweating, even when you are not hot 
• One or two body areas are sweaty, but the rest of your body is dry 
• Excessive sweating under your arms and on your feet, palms, and head 

You can try a few simple tips to minimize the effects of hyperhidrosis, including: 

• Use antiperspirant daily, not deodorant 
• Wear loose clothing of natural fibers such as cotton 
• Change your socks at least twice every day 
• Wear armpit shields to absorb perspiration 
• Avoid spicy foods and alcohol, as both can increase sweating 

Your dermatologist offers several effective treatments for hyperhidrosis and may recommend iontophoresis or Botox injections. 

Iontophoresis uses a weak electrical current passed through a wet cloth or water to block the sweat glands. Treatment is completely painless, and each treatment takes 20 to 30 minutes. Two to four weekly sessions are required, with maintenance sessions every one to four weeks. Iontophoresis take-home kits are also available. 

Botox injections reduce sweating in affected areas. Botox treatment requires 15 to 20 injections; each session takes 30 to 45 minutes. The sweat reduction effects can last several months, and you can repeat Botox treatment if necessary.
