Does the spleen refer to the organ?

In Korean medicine, the 'Spleen' does not refer solely to the anatomical spleen, but is the name of a system that describes digestion and nutrient transport functions. Spleen Yang Deficiency should not be understood as a disease of the anatomical spleen.

What other symptoms are evaluated?

We examine whether abdominal coldness, appetite, post-meal bloating, loose stools, a tendency toward edema, and fatigue change together.

Is all abdominal coldness considered Spleen Yang Deficiency?

No. There are other causes such as blood flow, gastrointestinal diseases, and lifestyle habits, so the duration of symptoms and accompanying changes must be checked together.

What records would be helpful?

Please record abdominal coldness and bloating before and after meals, the shape and frequency of bowel movements, changes after eating cold food, and fatigue. If there are signs such as abdominal pain, weight loss, or bleeding, a gastrointestinal evaluation takes priority.

In Spleen Yang Deficiency, 'Spleen' does not refer only to the anatomical spleen

Spleen Yang Deficiency describes a pattern in Korean medicine where abdominal coldness occurs along with post-meal bloating, loose stools, decreased appetite, edema, and fatigue. Since the 'Spleen' in Korean medicine is a functional system explaining digestion and nutrient transport, it is not the same as having a spleen disease.

Commonly confused terms and their differences: Abdominal coldness is a symptom felt by the patient, whereas Spleen Yang Deficiency is a pattern identification (Byeon-jeung) that interprets digestion, bowel movements, and systemic functions together. Other conditions such as gastrointestinal infections, inflammation, ulcers, or thyroid, liver, gallbladder, and pancreatic diseases are confirmed through medical history, physical examination, and tests; they are not distinguished solely by the fact that warm food provides relief.
Information to record before your visit: Please record abdominal coldness and bloating before and after meals, the location and duration of pain, and the shape, frequency, and color of stools. Preparing information on weight, appetite, vomiting, fever, edema, menstruation, relationship with specific foods, medications taken, and previous endoscopy or blood test results will help distinguish between medical causes and clues for pattern identification.
Scope of this material: WHO data was used to define the scope of traditional medicine terms for Spleen Yang Deficiency, and MedlinePlus data was used to distinguish various causes of abdominal pain and changes that require immediate confirmation. The explanation of Spleen Yang Deficiency does not diagnose spleen or gastrointestinal diseases, nor does it guarantee the efficacy of herbal medicine. Sudden severe abdominal pain, black or bloody stools, repeated vomiting, high fever, or weight loss must be evaluated by a doctor first.

Heat and Cold ColumnWhy is my abdomen cold? Is it simply a matter of blood circulation?

When symptoms of cold hands, feet, and abdomen persist, we look beyond simple lack of circulation to examine the causes and characteristics of coldness from a Korean medicine perspective and provide a checklist for self-assessment.

Heat and Cold ColumnCauses of abdominal coldness: Korean medicine treatment for when the abdomen feels cold and is accompanied by indigestion or diarrhea

We categorize abdominal coldness, where the abdomen feels cold and chilly, into decreased digestion, loose stools, post-meal fatigue, and lower abdominal coldness, and explain herbal medicine and acupuncture treatments to restore the spleen, stomach, and lower burner (lower abdomen and pelvic region).

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 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.
