The reason remote prescriptions are feasible is that the pathological mechanisms in many weight-loss patients are simpler than expected. From a Western medical perspective, appetite-regulating hormone imbalances and insulin resistance are common, leading to binge eating or carbohydrate addiction. In Korean medicine, this is often seen as spleen deficiency (脾虛): weakened spleen function fails to properly digest and transport food, generating phlegm-fluid retention (痰飮), which in turn stimulates appetite—a vicious cycle. This pattern can be largely identified through history-taking and tongue diagnosis (舌診); for example, a white coated tongue with loose stools or alternating constipation and diarrhea indicates typical spleen deficiency with phlegm. However, not all cases fit this profile. Those with stress-induced liver qi depression (肝氣鬱結) or blood stasis (瘀血) require pulse and abdominal examination. Therefore, I start with a remote consultation and recommend a visit if I sense the need for a more precise diagnosis. The advantages of a remote approach are time and cost savings, and a low barrier to starting treatment. The disadvantage is the lack of refined diagnostic methods. Based on my experience, many patients achieve satisfactory results remotely, but some need an in-person visit to clarify ambiguous patterns. Thus, rather than insisting solely on remote consultations, the most practical method is to begin remotely and transition to in-person care as needed. I learned this the hard way after initially insisting on remote-only consultations—now I adjust flexibly according to the situation.
