How is this different from Blood Deficiency (Hyeol-heo)?

Anemia is a medical condition diagnosed based on blood test standards, whereas Blood Deficiency (Hyeol-heo) is a Korean medicine concept that interprets a combination of various symptoms and clinical examinations. They cannot be used interchangeably.

What other symptoms are evaluated?

We check for fatigue, dizziness, shortness of breath during exercise, throbbing, paleness, headaches, and changes in menstrual flow. Treatment varies depending on the cause.

When are medical tests necessary?

If symptoms persist or if there is bleeding, black stools, heavy menstruation, or weight loss, blood tests and a cause evaluation are necessary. Severe shortness of breath, chest pain, or fainting must be evaluated promptly.

What is needed when receiving Korean medicine treatment concurrently?

You should share your recent blood tests, the diagnosed cause, and any medications you are taking, such as iron supplements. While maintaining your existing treatment, we will evaluate remaining cold sensitivity, fatigue, and digestive status through a medical consultation.

For anemia, both the levels and the cause are checked.

Anemia is a condition where red blood cells and hemoglobin lack the ability to transport oxygen. Depending on the cause and progression speed, there may be almost no symptoms, or symptoms such as fatigue, paleness, shortness of breath, and dizziness may appear. It is not judged solely by a feeling of being "tired," but by checking hemoglobin and red blood cell size through a complete blood count (CBC).

Commonly confused terms and their differences: Iron deficiency is one cause of anemia, but not all anemia is caused by iron deficiency. Bleeding, vitamin deficiency, kidney disease, and inflammatory diseases require different approaches; therefore, taking iron supplements for a long time without a test may delay the identification of the exact cause.
Information to record before your visit: If you have recent results for hemoglobin, mean corpuscular volume (MCV), iron, or ferritin, please have them ready along with the dates. Information regarding menstrual flow, black stools or other bleeding, dietary changes, possibility of pregnancy, and the level of activity that triggers shortness of breath and palpitations is also necessary to find the cause.
Scope of this material: NHLBI data was used to explain common symptoms of anemia and blood test ranges. This page is not a substitute for interpreting test results or a criterion for deciding whether to take iron supplements. If you experience chest pain, fainting, or severe shortness of breath even while resting, you must seek prompt medical evaluation.

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.

Heat and Cold ColumnCauses of cold fingertips, and Korean medicine treatment based on color changes, numbness, or neck pain

This distinguishes cold fingertips into Raynaud's phenomenon, nerve compression, or systemic coldness, and explains Korean herbal medicine and acupuncture treatments tailored to finger color changes, numbness, and neck and shoulder pain.

Heat and Cold ColumnIf the cause of coldness in the knees is not simply due to the cold weather, how should it be understood?

When a cold sensation in the knee area persists, we analyze the cause from the perspective of internal coldness rather than simple external temperature changes and provide a checklist for self-assessment.

Medical GuideWhen my hands and feet are cold and chilly, should I only think of it as cold hypersensitivity (Sujok Naengjeung)?

Symptoms of cold hands and feet vary, even under the single term 'cold hypersensitivity' (sujok-naengjeung). By distinguishing between color changes, differences between sides, numbness, and general fatigue, and by examining digestion, sleep, and lower abdominal coldness when tests show no clear cause, we can determine if Korean medicine treatment is appropriate.

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 ConceptHyeol-heo

Blood Deficiency (Hyeol-heo) is a Korean medicine category that groups various clues such as dizziness, paleness, palpitations, dryness, or numbness. It does not mean the same thing as anemia confirmed by blood tests, so they must be distinguished from each other.

Korean Medicine ConceptQi and blood deficiency

Qi and Blood Deficiency (Gi-hyeol-yang-heo) is a Korean medicine category determined by observing whether clues such as dizziness, paleness, palpitations, and coldness appear alongside fatigue and decreased recovery power. It is not the same as a diagnosis of anemia or chronic fatigue syndrome.

Symptom ExpressionCold Intolerance

Cold intolerance is a systemic symptom of being exceptionally sensitive to cold. After checking thyroid function, anemia, weight changes, and medications, any remaining coldness can be further examined from the perspective of Cold Syndrome (Han-jeung) and pattern identification (Byeon-jeung).

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.
