Excessive Sweating

Hyperhidrosis is excessive, uncontrollable sweating that goes beyond the body’s need to regulate temperature. Primary axillary hyperhidrosis affects the underarms and happens regardless of heat, activity, or stress. Botulinum toxin injections block the nerve signal that switches on the sweat glands, and are FDA-approved for severe underarm sweating in adults when topical antiperspirants do not work well enough.

What it is

Everyone sweats to cool down. Hyperhidrosis is when the body sweats far past that need, in a way that soaks clothing and interferes with everyday life.

The most common form is primary axillary hyperhidrosis, focused in the underarms, with no underlying illness behind it. It tends to run in families, often starts young, and happens regardless of the weather. It is common, affecting a meaningful share of the population, and it is a recognized medical condition, not a matter of hygiene or willpower.

The reason it responds so well to treatment is mechanical: the sweat glands themselves are normal, they are simply receiving too many “on” signals from the nerves. Quiet the signal and the sweating drops.

What causes it

In primary hyperhidrosis, the sweat glands are overactive because the nerves that control them fire too readily, not because anything is wrong with the glands or with the person’s health. It often begins in childhood or the teens and continues, and it is usually focused in specific areas, most often the underarms, but also the palms, soles, or face.

Sweating that is new, one-sided, or happens mostly at night can be a different, secondary kind tied to another condition or a medication, which is worth sorting out first. That is part of why a physician confirms the pattern before treating.

Is it the kind that responds

This is what the first visit confirms, because treatment fits some patterns and not others.

The value is not the list. It is that a physician confirms this is primary axillary hyperhidrosis, and that antiperspirants have been given a fair try, before treating, so the plan fits the condition rather than the request.

Why Santa Barbara Face & Body

Sweating is treated well when the physician takes it seriously as a medical condition, confirms the pattern, and places the injections precisely across the underarm. Dr. Pontius does exactly that, using an option that is FDA-approved for severe underarm sweating, and flags anything that looks like a secondary cause for evaluation first. Because severe axillary hyperhidrosis is a recognized condition, some insurance plans help cover treatment, which is worth checking.

When it is worth a consultation

Worth coming in if you

• Sweat through clothing regardless of temperature or activity
• Have tried clinical-strength antiperspirants without enough relief
• Plan your day, clothing, or seating around sweating
• Want a nonsurgical option that lasts months at a time

Better to talk it through first if you

• Are pregnant or breastfeeding
• Have a neuromuscular condition
• Have sweating that is new, one-sided, or mostly at night, which should be evaluated for another cause first

What to expect from a visit

Dr. Pontius confirms the sweating is primary and focused, checks that antiperspirants have had a fair try, and rules out signs of a secondary cause. Treatment is a series of small injections across each underarm, mapped to where you sweat most. You leave understanding whether you are a candidate, how long relief tends to last, and how to check whether your insurance helps with a recognized medical condition.

What we offer for this

People come in tired of soaking through shirts and leave with a plan matched to the pattern of their sweating. The underarm route is the one with the most evidence behind it.
