Diaphoresis

Related terms: sweating, sweat secretion, sweating

Sweating can be a normal response to exercise or heat, but if it recurs without a reason, it may be related to the thyroid, infection, menopause, medication, or autonomic nervous system responses. The timing, location, and accompanying symptoms must be considered together.

What is the difference between normal sweating and sweating as a symptom?

Sweating in response to hot environments or exercise is a thermoregulation response. If you experience recurring sweating that is difficult to explain or if it interferes with your daily life and sleep, it is necessary to identify the cause.

What else should be checked?

We examine whether it occurs throughout the whole body or in specific areas such as the hands, feet, or head; whether it is more severe during the day or night; and whether it is accompanied by sensations of heat, throbbing, weight changes, or fever.

Can medication also have an effect?

Some medications can increase sweating. Do not discontinue them arbitrarily; instead, inform your medical staff when the symptoms began and when any changes to your medication occurred.

What is evaluated during a consultation for heat and cold symptoms?

Following the necessary causal evaluation, we examine the direction of treatment by grouping the sweating with accompanying sensations of heat or cold, thirst, fatigue, and changes in sleep and digestion.

Record the situations in which you sweat along with changes in your body

Sweating is a normal response that lowers body heat as it evaporates from the skin. Sweating with a clear cause, such as hot environments, exercise, or nervousness, differs in scope of evaluation from sweating that recurs in cool places or during sleep. Therefore, you should distinguish the situation and time of day before the amount of sweat.

Commonly confused terms and their differences
Sweating (diaphoresis) refers to the general phenomenon of perspiring, while hyperhidrosis refers to a state of excessive recurrence that interferes with daily life. Conversely, cases where almost no sweat is produced but the body feels hot and dizzy also require a check for thermoregulation issues, so we do not look only at whether there is "too much sweat."
Information to record before your visit
For about one week, record the areas that get wet (such as the face, armpits, hands, or feet), the start time, indoor temperature, and the relationship with exercise, meals, or nervousness. It is also helpful to record any newly taken medications, throbbing, weight changes, fever, and whether your bedding gets wet at night to help narrow down the cause.
Scope of this material
MedlinePlus data was used to explain the thermoregulatory role of sweat and changes that require medical confirmation. Autonomic nervous system disorders or cold-heat patterns are not diagnosed by sweating alone; if accompanied by chest pain, shortness of breath, fainting, or unexplained weight loss, evaluation by a medical institution takes priority.

Medical GuideHow do I distinguish between sweat on the hands, feet, armpits, face, or night sweats?

Sweating that has occurred symmetrically in specific areas such as the hands, feet, and armpits since childhood and decreases during sleep requires a different verification process than sweating that has recently developed across the whole body or at night. You should organize the affected areas, onset timing, sweating during sleep, medications being taken, and how it interferes with your daily life.

Medical GuideIf I have night sweats and changes in temperature sensation, is it an autonomic nervous system problem?

Changes in sweating and temperature sensation may be related to the autonomic nervous system, but that alone cannot confirm the cause. By reviewing the timing and location of sweating, throbbing, changes in weight and sleep, and test results to categorize the heat and cold patterns, we can find points where Korean medicine treatment can help.
