Learn focal, generalised and medical review patterns before clinic assessment. ## Page Content Quick summary Hyperhidrosis means sweating that is greater than the body needs for normal temperature control. It may be focal, such as underarms, hands, feet or face, or more generalised. At Core Aesthetics, Corey Anderson RN assesses onset, pattern, severity, medicines, health history, prior management and medical review triggers before discussing whether clinic assessment, referral, waiting or no treatment is appropriate. ## Table of Contents - [What the term means](#what-the-term-means) - [Normal sweating versus hyperhidrosis](#normal-sweating-versus-hyperhidrosis) - [Primary focal hyperhidrosis](#primary-focal-hyperhidrosis) - [Secondary hyperhidrosis](#secondary-hyperhidrosis) - [Common areas affected](#common-areas-affected) - [How severity is assessed](#how-severity-is-assessed) - [When medical review should come first](#when-medical-review-should-come-first) - [What can be discussed at consultation](#what-can-be-discussed-at-consultation) - [What this page cannot decide for you](#what-this-page-cannot-decide-for-you) - [How Core Aesthetics approaches the concern](#how-core-aesthetics-approaches-the-concern) - [Which Pattern Needs Which Next Step?](#which-pattern-needs-which-next-step) - [What Should You Verify Before Booking?](#what-should-you-verify-before-booking) - [When Should You Book Or Seek Medical Review First?](#when-should-you-book-or-seek-medical-review-first) - [Next step](#next-step) ## What the term means Hyperhidrosis is the medical term for excessive sweating. It is not simply sweating on a hot day, sweating during exercise or sweating during understandable stress. It refers to sweating that is out of proportion to normal temperature control and that may interfere with ordinary life. For some people, the issue is wet clothing, visible sweat marks or frequent changes of shirts. For others, it is hand sweating, foot sweating, facial sweating or the constant planning that goes into avoiding awkward moments. The condition can be practical, social and emotional at the same time. ## Normal sweating versus hyperhidrosis Normal sweating helps the body cool itself. Hyperhidrosis is different because the sweating is excessive for the situation, persistent enough to be a pattern and disruptive enough to affect daily activity. A person might notice sweating in air-conditioned rooms, during quiet work, before social contact or with clothing choices that should otherwise be comfortable. The point is not whether a person sweats at all. The point is whether the sweating is disproportionate, recurrent and difficult to manage with ordinary measures. ## Primary focal hyperhidrosis Primary focal hyperhidrosis means excessive sweating that affects particular areas and is not clearly caused by another medical condition or medicine. It is sometimes described as idiopathic when no specific underlying cause is found. It often has a long history, affects both sides in a similar pattern and is most commonly noticed in the underarms, palms, soles or face. This pattern is the reason many people seek information about underarm sweating treatment or hyperhidrosis assessment. Even then, a consultation is still needed. A public page can explain the pattern, but it cannot decide whether an individual person is suitable for treatment discussion. ## Secondary hyperhidrosis Secondary hyperhidrosis means sweating that may be related to another medical issue, medicine or body change. It is more likely to be widespread, newer in onset or associated with other symptoms. Examples that need medical consideration can include fever, unexpected weight change, night sweats, thyroid concerns, diabetes, infection, menopause-related symptoms, medicine changes or other systemic features. This is why the history matters. If the sweating pattern does not fit a straightforward focal presentation, medical review may be the right first step. ## Common areas affected Focal hyperhidrosis commonly affects the underarms, hands, feet or face. Underarm sweating is the usual focus at Core Aesthetics because it is a common presentation and can be assessed in a clearly defined area. Palmar and plantar sweating can be more complex because hands and feet have different functional demands. Corey may discuss these concerns, but referral may be more appropriate where the area, symptoms or treatment risks sit outside the clinic scope. ## How severity is assessed Severity is assessed by listening first. Corey asks where sweating occurs, how long it has been happening, whether it affects both sides, what makes it worse, what has already been tried and how it affects work, clothing, social life, exercise and daily routines. Formal scoring tools, history, medical context and visible pattern can all help. The aim is not to make the concern sound dramatic. The aim is to understand whether the sweating is mild, moderate or severe enough to justify a treatment discussion, and whether another medical pathway should come first. ## When medical review should come first Medical review should come first if sweating has started suddenly, occurs mainly at night, is widespread rather than focal, follows a medicine change or appears with symptoms such as fever, chest pain, faintness, unexplained weight change or feeling generally unwell. That recommendation is not a brush-off. It is a protective step. Treating a local sweating symptom when the cause may be systemic can delay the care that actually matters.

Individual anatomy, suitability and treatment response vary. Not a treatment result or before-and-after image. ## What can be discussed at consultation A hyperhidrosis consultation can include conservative measures, antiperspirant use, previous medical advice, referral options, treatment suitability, risks, limits and review planning. Some options involve prescription-only medicines, which means they are discussed privately after assessment rather than advertised as public product information. Consultation comes first. If treatment is suitable and appropriate on the day, this can be discussed with Corey during your appointment. Booking a consultation means assessment comes first, and treatment only proceeds when it is clinically appropriate.

It cannot diagnose you, rule out secondary causes or promise that treatment is appropriate. It also cannot promise complete dryness or permanent change. Sweating is a normal body function, and treatment planning, where appropriate, is about reducing a specific problem in a realistic and clinically responsible way. ## How Core Aesthetics approaches the concern Core Aesthetics takes a consultation led approach. Corey Anderson RN reviews the sweating pattern, medical history, medicines, prior management and expectations before any treatment discussion. The conversation may lead to treatment planning, conservative management, referral or a decision not to proceed. That can sound less exciting than a fast answer. Good. Excessive sweating deserves more than a shortcut. It deserves careful assessment, particularly when a person has spent years organising daily life around the problem.

The safest pathway depends on the sweating pattern, not just the word hyperhidrosis. Pattern What it can suggest Safer next step Longstanding underarm sweating A focal pattern that may be suitable for clinic assessment if it affects daily life. Book consultation if you want Corey to assess severity, suitability, risks and realistic options. Hands, feet or face These areas can have different functional and risk considerations. Discuss the pattern, but referral or another pathway may be more appropriate. New, widespread or night sweating This can point toward a medical or medicine related cause. Seek GP or specialist review before elective cosmetic treatment discussion. Sweating with symptoms Fever, chest pain, faintness, unexplained weight change or feeling unwell should not be treated as routine cosmetic concern.

Hyperhidrosis means excessive sweating that goes beyond what the body needs for temperature control. It may affect one area, such as the underarms, hands, feet or face, or it may be more generalised. A clinical assessment helps decide whether the pattern is likely to be primary focal hyperhidrosis or related to another cause. How is hyperhidrosis different from normal sweating? Normal sweating helps regulate body temperature. Hyperhidrosis is sweating that is out of proportion to the situation, happens repeatedly and affects daily life. The distinction is based on the pattern, duration, triggers, severity and whether there are medical features that need review. What is primary focal hyperhidrosis? Primary focal hyperhidrosis is excessive sweating in particular areas without an obvious underlying medical cause. It often affects both sides in a similar way and may involve the underarms, palms, soles or face. It still needs assessment before treatment options are discussed. What is secondary hyperhidrosis? Secondary hyperhidrosis is sweating that may be related to a medical condition, medicine or body change. It can be more widespread or newer in onset. If secondary hyperhidrosis is possible, GP or specialist review may be needed before any clinic treatment pathway is considered. Which body areas are commonly affected by hyperhidrosis? Focal hyperhidrosis commonly affects the underarms, hands, feet or face. Core Aesthetics most commonly assesses underarm sweating concerns. Hand, foot or facial sweating may need different planning or referral depending on the pattern and risk profile. When should I see a doctor about excessive sweating? See a doctor promptly if sweating starts suddenly, occurs mainly at night, is widespread, follows a medicine change or occurs with symptoms such as fever, chest pain, faintness, unexplained weight change or feeling generally unwell. These features should not be treated as routine cosmetic concerns. Can hyperhidrosis be managed? Yes, many people can manage hyperhidrosis with a combination of practical measures, topical products, medical review and, where suitable, clinic treatment options. The right pathway depends on the cause pattern, severity, medical history and what has already been tried. What happens if my sweating pattern seems suitable for clinic assessment? Corey reviews your history, sweating pattern, prior management, medicines and expectations. If treatment discussion is appropriate, risks, limits, consent, timing and review planning are explained. Same day treatment may be discussed only if it is clinically appropriate and informed consent is completed. What does Corey assess when someone asks about excessive sweating consultation planning? Corey assesses where sweating occurs, when it started, whether it is focal or generalised, what worsens it, what has already been tried, medical history, medicines, skin condition, severity, impact on daily life and whether GP review should come first.
