What is checked during the medical evaluation?

We examine the onset of symptoms, situations that worsen them, the distribution of heat and cold sensations, changes in sleep, sweat, thirst, digestion, and bowel movements, as well as pulse diagnosis.

Is this the same as a differential diagnosis?

They are not the same. Differential diagnosis is the medical process of distinguishing between diseases that produce similar symptoms, while pattern identification (Byeonjeung) is the process of determining the direction of Korean medicine treatment based on the necessary differential diagnosis.

Can a pattern identification be made based on a single symptom?

A single sensation of heat or cold is not sufficient. For example, with heat in the soles of the feet, the category to be examined changes depending on whether it worsens at night, whether there is numbness, or whether dry mouth and sweating are present.

Once a pattern identification is determined, does it not change?

Since pattern identification describes the state at the time of the evaluation, it can change based on the progress of treatment, season, and changes in sleep and lifestyle. If symptoms change, we do not simply apply the previous judgment but undergo medical interviewing and examination again.

Pattern identification and disease diagnosis answer different questions

Pattern identification is the process of grouping symptoms, tongue, pulse, and abdominal findings gathered during interviewing and examination according to Korean medicine theory to review the direction of treatment. Even with the same disease name, current discomfort and examination findings may differ; conversely, similar pattern identification expressions may be used across various diseases.

Commonly confused terms and their differences: Disease diagnosis is the process of confirming the criteria for a specific disease through medical history, examination, and tests, whereas pattern identification interprets the confirmed medical information and current symptom patterns within the framework of Korean medicine treatment. A pattern identification name does not replace blood tests or imaging results, and differential diagnosis to ensure no disease is missed comes first.
Information to record before your visit: Please note your three most uncomfortable symptoms and their onset, as well as changes in sleep, diet, bowel movements, menstruation, and sweat, and prepare your recent test results and medications. If there are changed findings since your last visit, asking what has changed will allow you to receive an explanation focused on your actual progress rather than just the pattern identification name.
Scope of this material: WHO data was used for the standard terminology of pattern identification and the four examination methods, and MedlinePlus data was used to distinguish the procedures of medical differential diagnosis. Pattern identification does not replace emergency care or confirmatory tests, and this explanation itself does not guarantee the efficacy of any specific Korean medicine treatment.

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 ColumnReasons why the body feels cold, and Korean medicine treatment when coldness in the hands, feet, and abdomen is accompanied by fatigue

This explains how to distinguish the reasons for a cold body from thyroid issues, anemia, and Raynaud's phenomenon, and describes how Korean herbal medicine and acupuncture treatments vary when coldness in the hands, feet, and abdomen is accompanied by poor digestion, fatigue, or edema.

Medical GuideWhat should I record before a consultation for heat or cold sensations?

Even if the cause was not revealed in tests, you can describe your discomfort in detail. By noting the onset time, location, times when symptoms worsen, and changes in sweating, numbness, dry mouth, or sleep, and by preparing previous test results and medications, we can more accurately examine the patterns of heat and cold and 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 ConceptHan-yeol

Cold-Heat (Han-yeol) is a criterion for dividing the body's current tendency by looking not only at feelings of cold or heat, but also accompanying patterns such as thirst, sweating, digestion, and sleep. It does not mean the same thing as a single thermometer reading.

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.

Medical TerminologyPulse Diagnosis

Pulse diagnosis is a Korean medicine examination that checks the pulse at the wrist. A diagnosis is not determined by pulse diagnosis alone, but is interpreted alongside medical interviews, other examinations, and existing test results.
