How is this different from having a heat-prone constitution?

Hyperthyroidism is a condition where hormonal changes are confirmed through testing. You should not dismiss symptoms as simply being part of your constitution just because you feel hot and sweat.

If you are taking medication

Do not stop taking your medication or change the dosage on your own; consult the medical staff who prescribed it. When receiving Korean medicine treatment concurrently, you must inform the provider of your current medications and test results.

What tests and symptoms are evaluated together?

Hyperthyroidism is diagnosed through blood tests to check thyroid hormone and thyroid-stimulating hormone (TSH), as well as physical examinations and cause evaluations. In addition to heat sensitivity, we check for palpitations at rest, hand tremors, diarrhea, anxiety, muscle weakness, and unintended weight loss.

Where does the heat-cold treatment continue?

First, the diagnosis and treatment of the thyroid condition are maintained. For remaining sensations of heat, sweating, sleep issues, or digestive discomfort during treatment, the medical evaluation determines the scope of help possible from the perspective of heat-cold balance and pattern identification (Byeonjeung), based on recent test results and medications.

Are there changes that need to be checked immediately?

If severe palpitations, chest pain, difficulty breathing, high fever, or changes in consciousness occur, do not view them as mere heat-cold symptoms and seek prompt medical evaluation at a medical institution.

Even if you feel hot and sweat more, a thyroid test comes first

Hyperthyroidism is a condition where there is more thyroid hormone in the body than needed, which can cause heat sensitivity, sweating, palpitations, hand tremors, sleep changes, and weight loss. The intensity of symptoms varies by person, so a diagnosis is not made based on heat sensation or weight change alone.

Commonly confused terms and their differences: Heat syndrome (Yeol-jeung) is a Korean medicine category used to describe current symptom patterns, whereas hyperthyroidism is a disease confirmed by TSH and thyroid hormone blood tests and cause evaluations. Even if facial heat or anxiety appear similar, a pattern identification name does not replace tests and medical treatment.
Information to record before your visit: Please record your recent resting heart rate, weight changes, and when hand tremors, diarrhea, sleep changes, or menstrual changes began. It is easier to confirm the cause and treatment response if you inform the medical staff of your TSH and free thyroid hormone results, prescribed medication dosages, and whether you use iodine-containing medications, contrast agents, or health functional foods.
Scope of this material: MedlinePlus data was applied to the symptoms, causes, and test scope of hyperthyroidism. This page does not diagnose thyroid disease; do not arbitrarily reduce thyroid medication or replace it with herbal medicine or health functional foods to lower heat sensations. Immediate medical evaluation is required if a very fast or irregular pulse occurs along with chest pain, difficulty breathing, changes in consciousness, and high fever.

Heat and Cold ColumnReasons for feeling hot: Korean medicine treatment for when you cannot tolerate heat despite a normal body temperature

If your body always feels hot and you sweat a lot despite a normal body temperature, we categorize issues related to the thyroid, menopause, medication, and recovery capacity, and examine Korean herbal medicine and acupuncture treatments tailored to heat sensitivity and accompanying symptoms.

Heat and Cold ColumnI sweat every night and feel heat in my body; what are the causes of night sweats?

We provide guidance on the Korean medicine perspective on the causes of night sweats and heat rising to the hands, feet, or face despite normal test results, as well as criteria for self-assessment.

Medical GuideWhere should I start checking when sensations of heat and cold recur?

Even if there are no clear abnormalities in tests, recurring sensations of heat and cold are a definite discomfort. By gathering information on the area, time of day, duration, and accompanying changes such as sleep, sweat, and digestion, we can examine the branches of symptoms more precisely from the perspective of heat and cold and determine the direction of Korean medicine treatment.

Medical GuideWhat should I check if tests are normal but sensations of heat and cold persist?

Just because a cause was not found in a test does not mean the symptoms the patient feels do not exist. The Baekrokdam Heat-Cold Clinic respects existing results while examining details not captured in test reports, such as location, timing, sleep, sweat, and digestion, categorizing them by heat-cold patterns to find points where Korean medicine treatment can help.

Comparison of similar terms

Korean Medicine ConceptHeat syndrome

Heat syndrome refers to a tendency where various body signals converge toward a 'hot' direction. It is not a disease name referring to fever caused by infection or thyroid disease, so necessary differential diagnosis is required first.

Symptom ExpressionNight sweats

Night sweats are symptoms where a large amount of sweat occurs repeatedly during sleep. In addition to indoor temperature, factors such as infection, hormonal changes, medication, and thyroid problems must be checked.

Medical TerminologyDifferential Diagnosis

Differential diagnosis is the process of distinguishing possible causes one by one through examination, testing, and monitoring progress, rather than determining a disease name based on a single symptom. This is the first and most necessary step for both sensations of heat and cold.
