ClinicaSU is the first center in Italy capable of offering all the main therapies for abnormal sweating and hyperhidrosis in a single facility.
For us, they are not synonyms: we distinguish between the different causes of sweating and build a diagnostic and therapeutic pathway based on scientific evidence, avoiding standardized and superficial approaches. Our goal is to identify the most effective solution for each individual patient.
Hyperhidrosis:
definition, etymology, and clinical classification
Excessive sweating, clinically known as hyperhidrosis, is a medical condition characterized by sweat production that exceeds the body's actual thermoregulatory needs. It is not merely a cosmetic concern, but a complex functional alteration of neurovegetative control.
Sweating is an essential physiological function that allows the human body to regulate its internal temperature (thermoregulation). However, it does not only respond to thermal stimuli, but is regulated by the sympathetic nervous system in response to emotional, hormonal, and physiological factors. When this mechanism exceeds the need for cooling, it is referred to as hyperhidrosis — a condition that impacts daily comfort and social interactions.
Etymology: what does hyperhidrosis mean?
The term derives from ancient Greek and is composed of two fundamental roots:
Prefix
ὑπέρ
hyper — "excessive", beyond the norm
Noun
ἱδρώς
hidrōs — "sweat"
Literally "excessive sweating", in modern medicine the term defines the failure of the physiological mechanism that regulates body thermal balance, mediated by the hypothalamus → sympathetic system → eccrine sweat glands axis.
Pathophysiology: why does the system lose control?
In hyperhidrosis, the autonomic nervous system loses its capacity for fine regulation. The disorder manifests through three key factors:
- 1Lowering of the activation threshold: the sympathetic system overresponds to minimal stimuli.
- 2Hyper-reactivity: a disproportionate response to thermal, emotional, or mechanical stimuli.
- 3Reduction of inhibitory control: the hypothalamus fails to properly modulate the sudomotor discharge.
Classification of hyperhidrosis
Primary focal
Most common form, not linked to pre-existing conditions
Genetic familiarity in 30–50% of cases.
- Onset: childhood or adolescence.
- Sites: palms, soles of the feet, armpits, face, scalp.
- Mechanism: cholinergic sympathetic hyperactivity (T2–T4 segments).
Secondary generalized
Symptom of an underlying systemic condition
Can also occur during night rest.
- Onset: more frequent in adulthood.
- Causes: endocrine disorders, diabetes, obesity, neoplasms, medications, anxiety.
- Mechanism: systemic metabolic or hormonal imbalances.

Diagnosis of Hyperhidrosis:
the first step towards the most appropriate treatment.
If excessive sweating affects your daily life, the first step is to understand where the problem comes from. Before choosing a treatment, it’s essential to distinguish primary hyperhidrosis from a secondary form, which may be associated with other medical conditions or the use of certain medications.
At the ClinicaSU, the diagnosis is based on a thorough specialist assessment and on the international ABCDE‑F protocol, one of the main clinical references for evaluating primary hyperhidrosis.
Book your specialist assessmentA – Age of Onset
Primary hyperhidrosis most commonly appears during childhood or adolescence. Many patients live with the condition for years before consulting a specialist, often thinking it is a personal characteristic or simply learning to live with it.
B – Bilateral
Sweating generally affects both sides of the body symmetrically, mainly involving:
- Face and scalp; - Armpits; - Palms of the hands; - Soles of the feet.
Localized sweating on only one side of the body requires a diagnostic evaluation.
C – Cessation During Sleep
Primary hyperhidrosis tends to stop during sleep. If sweating persists even at night, the specialist may consider further tests to rule out a secondary form.
D – Duration of Symptoms
For the diagnosis of primary hyperhidrosis, the symptoms must have been present for at least six months.
E – Frequency of Episodes
The diagnosis also takes into account the impact of the disorder on the quality of life. Recurrent episodes, occurring at least twice a week and interfering with work, study, social or sports activities, represent an important element of the assessment.
F – Family
In approximately two‑thirds of patients, there is a familial component. During the specialist consultation, a detailed medical history is taken to identify any similar cases within the family.

Hyperhidrosis: Answers to Frequently Asked Questions
- 1. Why choose ClinicaSU?
- 2. Why do I sweat excessively even without heat or physical exertion?Hyperhidrosis is a condition of the autonomic nervous system that causes sweating beyond actual thermoregulation needs. It is not merely a cosmetic issue, but a disruption of neurophysiological regulation that requires a targeted specialist evaluation.
- 3. How is the most suitable treatment determined for my case?The therapeutic choice is not standardized but is based on a comprehensive clinical evaluation that considers the type of hyperhidrosis, the areas involved, severity, and individual response. The pathway always follows a progressive approach, from the least invasive solutions to advanced options, including surgery when necessary.
- 4. Why is ClinicaSU different from other centers?ClinicaSU adopts the Ultra Viola Method, an approach that interprets hyperhidrosis as a disruption of autonomic nervous system regulation and not just as a skin issue. The goal is not to suppress the symptom, but to modulate the neurophysiological response through an integrated pathway that includes conservative therapies, advanced technologies, and functional surgery in selected cases.
- 5. Do MiraDry® thermal technologies offer permanent results?Thermal technologies allow for a significant and often long-lasting reduction in sweating in the treated area and in bromhidrosis (odor). The response is individual and is always evaluated within the context of the entire sudomotor system.
- 6. When is it necessary to resort to surgery?Surgery (endoscopic thoracic sympathectomy) is indicated in cases of severe palmar hyperhidrosis when conservative and minimally invasive treatments are insufficient. The indication is always carefully evaluated against the benefit-risk ratio, particularly regarding potential compensatory sweating.
- 7. When is it advisable to book a visit?It’s time to consult a specialist if:
- the sweating is excessive relative to the temperature or the activity being performed;
- it limits work, study, or social life;
- it causes discomfort or embarrassment in everyday relationships;
- it has been present for over six months;
- mainly interested in the face, armpits, hands, and feet.
A specialist assessment allows you to identify the cause of the sweating and determine the most appropriate treatment plan for your needs, with the aim of improving your quality of life and daily well‑being.
