In clinical consultations, many patients ask, 'Everyone else says it's great, so why am I feeling this way?' These reactions typically fall into two categories. First, those with a 'Spleen Deficiency' (Bi-heo, 脾虛) type—where digestive functions are weak—may feel bloated or lethargic during the first few days. Conversely, those with an accumulation of 'Phlegm-Fluid' (Dam-eum, 痰飮) or 'Blood Stasis' (Eo-hyeol, 瘀血) may experience a temporary feeling of heaviness as the body begins to clear waste products, often referred to as a healing crisis or detoxification reaction. Having experienced the frustration of trial-and-error with weight loss myself, I never tell patients to simply 'endure' uncomfortable symptoms. TKM emphasizes tailoring the medicinal composition and concentration to the individual's constitution. For instance, if heart palpitations are severe, we add calming herbs; if energy levels drop too low, we incorporate tonic herbs to replenish vitality. Herbal weight loss medicine is not merely an appetite suppressant, but a tool to restore the body's collapsed equilibrium. Because responses vary wildly depending on one's constitution and underlying health conditions, it is essential to maintain open communication with your practitioner to fine-tune the prescription based on your body's real-time changes.
