At Sutran, we have been listening for over ten years to people who, like you, battle daily against excessive sweating in the armpits. We don’t speak from theory: we know axillary hyperhidrosis firsthand and have turned that knowledge into smart garments that let you live free of stains, odors, and nerves.
In this article, created by our team, we explain everything you need to know to understand the causes, detect the symptoms, and—above all—put an end to them practically.
What is axillary hyperhidrosis and how does it affect us?
Axillary hyperhidrosis is much more than “sweating a little too much.” It is a chronic overproduction of sweat unrelated to ambient temperature or physical activity. When the sympathetic nervous system sends erratic signals to the eccrine sweat glands in the armpit, they activate fully... even while sitting on the couch.
Why do we sweat so much in the armpits?
The armpits concentrate a large number of eccrine and apocrine glands. Normally, their function is to regulate temperature and eliminate toxins. In those of us who suffer from hyperhidrosis, the nervous signal goes off the charts, and sweat production skyrockets.
Difference between normal sweating and hyperhidrosis
| Normal Sweating | Axillary Hyperhidrosis |
|---|---|
| Activated by heat, exercise, or brief stress | Appears—or intensifies—without apparent reason and daily |
| Moderate amount, easy to evaporate | Liters of sweat soaking the shirt, sometimes dripping! |
| Usually doesn’t leave persistent stains | Dark circles on clothes and odor due to bacterial proliferation |
Main causes of excessive sweating in the armpits
At Sutran, we always recommend a medical check-up to rule out underlying diseases (hyperthyroidism, diabetes, etc.). However, the most common causes we see in our community are:
-
Genetics and family inheritance
If your father, mother, or grandparents already struggled with sweat, you have a high chance of inheriting it. Primary hyperhidrosis usually has a clear genetic component. -
Hormonal changes and nervous system
Menopause and andropause: hot flashes completely alter the internal thermostat.
Chronic stress situations: the sympathetic nervous system remains in “alert” mode. -
Medical conditions and medications
Sometimes, hyperhidrosis is secondary to treatments with antidepressants, beta-blockers, or hormone therapies. If you take medication and notice a sudden change, consult your specialist.
How axillary hyperhidrosis manifests
Most common warning signs
-
Circular stains every few hours, even in mild weather.
-
Feeling of always wet armpits—the shirt never dries.
-
Strong odor a few hours after showering.
-
In severe cases, sweat running down the side.
Physical and emotional impact
Sweat doesn’t just wet fabric; it soaks self-esteem. Many customers come to Sutran after years avoiding:
-
Hug greetings.
-
Wearing light colors.
-
Public speaking for fear of “those treacherous stains.”
The good news is that simple strategies make all the difference.
Effective tips to control axillary hyperhidrosis
Hygiene habits and textile hygiene
-
Short, lukewarm shower every morning.
-
Dry the area well with a towel specific for armpits.
-
Change underwear when you feel accumulated moisture.
Diet and emotional factors
Reducing coffee, alcohol, and spicy food lessens sweat peaks. Combining it with diaphragmatic breathing or mindfulness helps control the sympathetic response.
Topical products and antiperspirants
In moderate cases, we use antiperspirants with aluminum chloride. Still, many users tell us they continue staining clothes; that’s why they combine antiperspirants with Sutran technical garments.
What treatments exist for axillary hyperhidrosis?
Medical options: botulinum toxin, surgery, and drugs
-
Botox®: blocks nerve endings for 4-6 months.
-
Sympathectomy: surgical option for extreme cases.
