Some people sweat through their palms during a normal conversation, or soak through a shirt with no heat or exertion behind it. That’s hyperhidrosis, a condition where sweat glands work past what the body actually needs for cooling, usually concentrated in the underarms, hands, or feet.
A dermatologist looks at where the sweating occurs and how severe it is before deciding on a treatment plan.
Understanding the Condition Before Treatment Begins
A dermatologist usually starts by asking about medical history: when the sweating began, which areas it affects, whether it happens during sleep. Blood work or a sweat test sometimes follows, mainly to rule out something like an overactive thyroid.
From there, the diagnosis comes down to whether it’s primary hyperhidrosis, with no clear cause, or secondary hyperhidrosis, tied to a medication or another condition. That difference is what determines the treatment plan.
Topical and At-Home Options
Hyperhidrosis treatment often begins with prescription antiperspirants containing aluminum chloride, applied at night and reduced to once or twice weekly once sweating settles. Underarm sweating also responds to medicated wipes containing glycopyrronium.
For the hands and feet, iontophoresis is a common option. This device runs a mild current through water and needs several sessions before results become noticeable.
When Sweating Needs a Stronger Response
If topical treatments aren’t enough, botulinum toxin injections are usually the next step. They block the nerve signals that trigger sweat glands, and results typically last four to twelve months for the underarms, three to six months for the hands, or three to six months for the feet.
Microwave therapy uses heat to destroy sweat glands in your underarms, usually over two sessions. Oral meds work differently. Since they cut down on sweating across your entire body, they’re typically a better fit for people who deal with excessive sweat in more than just one area.
Surgery as a Last Resort
Surgery is usually the last option, considered only when other treatments haven’t worked. It might mean removing the sweat glands, or cutting the nerves that trigger them in a procedure called sympathectomy. The trade-off is compensatory sweating, where the body starts sweating more in other areas to make up for the part that was treated.
Treatment isn’t one-size-fits-all here. What works for someone with sweaty palms won’t necessarily help with underarm sweating, so the plan really comes down to where it’s happening, how bad it is, and what the person is comfortable trying.
