Does Your Child Suffer From Plantar Hyperhidrosis (Sweaty Feet)?

As adults we tend to look back on our adolescent years fondly, forgetting much of the anxiety, and remembering the carefree days we spent not worrying about “adulting.”  

However, our adolescent days are definitely a time of physical, mental, and emotional changes, where we were easily embarrassed, bullied, and shamed for factors often out of our control.  

Factors like Plantar Hyperhidrosis, a condition entailing excessive sweating of the feet, can have a large impact on adults, let alone the fragile adolescent psyche.  

That is why I found the results of this particular research interesting and encouraging for the future treatment of this condition in juvenile cases.


In the United States hyperhidrosis affects 1.6% of all adolescents.  

Research shows this is usually a hereditary condition, very rarely caused by a serious health problem.  

If you are considering treating your child’s sweaty feet, you may want to discuss your desires with a dermatologist or pediatrician.  

Other conditions that can cause hyperhidrosis are diabetes, metabolic or hormonal disorders, and hyperthyroidism.  

Sweaty feet do not necessarily mean a deeper medical issue is lurking, but it is always wise to have your Dr. involved to assure there are no other signs or symptoms of an internal condition . 


Treatments for sweaty feet in kids vary, but commonly include hefty antiperspirants and surgical interventions.  

New research in pediatric dermatology has demonstrated great success in treating adolescent plantar hyperhidrosis, or sweaty feet, with botulinum type A toxin (known more commonly by the brand name Botox)!  

In Dr. Bernhard, Dr. Krause, and Dr. Syrbe’s research they tested the effectiveness and safety of botulinum type A toxin in adolescent cases.  

When conducting their study, they used 50 to 100 units per sole, per participant, and saw the most success with 75 to 100 units per sole.  

Researchers found that 73% of participants involved in the study reported positive outcomes from the treatment, and there were no severe side effects!  

These results are exciting because, though botulinum type A toxin is currently only approved for use in adult cases of hyperhidrosis, it may one day be available as a safe and effective treatment for cases of plantar hyperhidrosis in adolescents.
