How do I distinguish between sweating on the hands, feet, armpits, face, or night sweats?

First, mark the areas where you sweat

Note where the sweating starts first among the palms, soles, armpits, face/scalp, chest/back, or the entire body. Even if multiple areas like the hands and feet are wet, the area that most disrupts your daily life may differ. It is more useful for the medical evaluation to record specific scenarios, such as hand sweat affecting writing, shaking hands, or using devices; foot sweat affecting sock changes, odor, or skin maceration; armpit sweat affecting clothing choices; and facial sweat affecting meals, conversation, or makeup.

Distinguish whether it started in childhood or more recently

Sweating that has occurred since a relatively early age in areas such as the hands, feet, armpits, or face, appearing symmetrically on both sides and decreasing after falling asleep, may be a clue for primary focal Hyperhidrosishyperhidrosis. Conversely, if sweating across the whole body has suddenly increased recently or if clothes and bedding become wet during sleep, other causes such as medications, thyroid issues, blood sugar, infection, or menopausal changes must be checked first. This distinction alone does not confirm a diagnosis.

Note the triggers and changes during sleep

Observe whether sweating is triggered by scenarios such as presentations, exams, driving, meals, or meeting people, in addition to hot environments and exercise. While tension can increase sweating, it should not be dismissed as simply a "mindset issue." The process of becoming worried about sweating itself may be a burden that developed Sweating through repetition. Whether sweating decreases after falling asleep or worsens at night is also a critical point of distinction.

Check medications and accompanying changes together

Note any newly started or dosage-changed prescription medications and supplements, as well as changes in weight, throbbing, hand tremors, fever, cough, diarrhea, or menstrual changes. Even if you suspect a medication is the cause, do not stop taking it arbitrarily; consult the prescribing medical professional. If suddenly occurring Cold sweatschest pain, shortness of breath, or a feeling of fainting occur together, you should seek prompt medical evaluation rather than waiting for a hyperhidrosis appointment.

For night sweats, record both the amount and changes in recovery

If you wake up due to sweat even in a cool room, do not just record the amount of sweat. Record the number of times you wake up, how long it takes to fall back asleep, whether you changed your clothes or bedding, and how your fatigue was the next day in that order. Even while the amount of sweat remains similar, sleep and next-day condition may change first, so these are compared when determining the direction of treatment.

These records alone do not determine the treatment outcome. Guide to Night Sweats and Nocturnal HyperhidrosisYou can continue by reviewing the systemic symptoms that must be checked first, followed by the sequence for determining the treatment progress after examinations.

Distinguish between the effects and discomforts of previously used methods

If you have used antiperspirants, topical medications, iontophoresis, oral medications, botulinum toxin injections, or surgery, please record when and where they were used and what changes occurred. Also, document discomforts such as skin irritation or dry mouth, and any experiences of increased sweating in other areas. Rather than viewing previous treatments as failures, separating the effective parts from the remaining discomforts allows for the determination of the next steps.

There is a different evaluation sequence if facial and head sweating is prominent only during meals

Even if sweating occurs only in upper areas like the face and scalp, the questions must be more specific if it repeats during meals. The evaluation sequence for facial sweating changes depending on whether it starts from the first bite, spreads as the face flushes after a few spoonfuls, or occurs late after the meal like a cold sweat.

In particular, if this is accompanied by coldness in the hands and feet, decreased energy, or bloating after meals, it may not be a problem that can be solved simply by saying "reduce spicy foods." This is because the moment heat surges upward and the moment recovery weakens after sweating must be viewed together. In such cases, When sweating occurs on the face and head after eating: heat regulation to check before looking at foodyou can continue by reviewing how to choose dining-out menus and in which scenarios consultation should take precedence over lifestyle management.

The focus of treatment is determined during the heat-cold (Han-Yeol) evaluation

If the influence of other diseases or medications is identified, treating those causes and adjusting prescriptions takes priority. After necessary evaluations are complete, if a consistent pattern of localized sweating, sensations of heat or cold, and sleep, digestion, or fatigue remains, we examine how Korean medicine treatment can help from the perspective of heat-cold (Han-Yeol) and pattern identification (Byeon-Jeung). Whether to proceed centered on Korean medicine treatment or in parallel with existing treatments is decided during the medical evaluation after confirming your current state and previous treatments. Lifestyle management is adjusted together as a method to support the treatment.
