What Causes Excessive Hand Sweating?
Excessive sweating, medically known as hyperhidrosis, is typically categorized into two types: primary hyperhidrosis and secondary hyperhidrosis.
Primary hyperhidrosis is often inherited and usually affects specific areas of the body, such as the hands, feet, underarms, and face. In this condition, overactive nerve signals cause the sweat glands in these areas to produce more sweat than necessary.
Secondary hyperhidrosis, on the other hand, is caused by an underlying medical condition or is a side effect of certain medications. This type often results in sweating across larger areas or the entire body. Common triggers include medications such as antidepressants, diabetes treatments, pain relievers, and certain antibiotics. Medical conditions that may lead to secondary hyperhidrosis include thyroid disease, hormonal changes (such as menopause), infections, diabetes, some types of cancer, and neurological disorders.
Are There At-Home Remedies for Hand Sweating?
A common and accessible starting point is the use of antiperspirants. Over-the-counter options are widely available in various strengths and can be quite effective for many people.
For more persistent cases, a general dermatologist can help determine whether prescription-strength topicals or oral medications are appropriate. They may also recommend an at-home iontophoresis device. This device uses water and a mild electrical current to reduce sweating by temporarily thickening the outer layer of skin on the palms, which helps block sweat from reaching the surface. Treatment requires multiple sessions and regular maintenance for continued benefit.
What Treatments Can Help Sweaty Palms?
In cases where other approaches aren’t sufficient, neuromodulator injections (Botox, Dysport, Jeuveau, etc.) can significantly reduce sweating in targeted areas such as the hands, underarms, and face. Neuromodulators work by temporarily blocking the nerve signals and the release of acetylcholine which stimulates the glands to produce sweat.
The procedure is done in a medical office by a trained professional. Don’t let the word “injection” scare you! Patients find treatment well tolerated with the help of topical numbing or comfort measures like Pronox (similar to laughing gas). The treatment is generally safe, with possible side effects being temporary and including mild bruising or redness at the injection site. Neuromodulators should be avoided during pregnancy, while breastfeeding, or in individuals with certain neuromuscular conditions.
How Long Do the Results Last?
The effects of neuromodulators typically last between 4 to 6 months, after which sweating gradually returns to its original levels. Repeat treatments are necessary to maintain results.
Will Treating Hand Sweating Cause Other Areas to Sweat More?
No, treating excessive hand sweating with neuromodulators does not cause compensatory sweating in other parts of the body. Each treatment area responds independently.
