I understand that 'constitution' can sound vague at first, but after over a decade of clinical practice, I've found it genuinely helpful. Let me walk you through the process step by step. First, during the initial consultation, I ask about lifestyle habits and past diet experiences—for example, 'Do you often eat late-night snacks?' or 'Is your digestion usually poor?' These questions help detect signs of spleen deficiency (biheo), meaning weakened spleen function. At the same time, pulse diagnosis (maekjin) checks the overall flow of qi and identifies any impurities like phlegm-fluid (dameum) or blood stasis (eohyeol). Second, the key step is Sasang constitution (sasang chejil) differentiation. This isn't about body shape but about the balance of your internal organs. For instance, Taeum type tends to have a relatively strong liver and weak lungs, making them prone to rebound weight gain or fatigue during dieting. Soyang type, on the other hand, often has a weak spleen, so controlling appetite matters more than overeating. Ignoring this and simply cutting calories often backfires because the body resists—I learned this through trial and error myself. Third, we prescribe herbal medicine according to your constitution and current state: if spleen deficiency is severe, we add herbs to tonify the spleen (bobi); if phlegm is abundant, we add herbs to resolve phlegm (idam). Diet and exercise recommendations also vary by constitution—for example, aerobic exercise and low-salt diets suit Taeum types, while strength training and protein-rich meals work better for Soyang types. It's not mandatory, just a suggestion based on experience. Finally, we schedule follow-ups every 2–4 weeks to monitor changes and adjust the plan. While your constitution is fixed, your body's condition changes over time. This repeated process helps you find your own rhythm and reduces the risk of rebound weight gain. Feel free to ask any questions—you're always welcome.
