Q. I want to know why I keep gaining weight. How can I figure out the cause of my obesity?

To determine the cause of weight gain, Traditional Korean Medicine approaches it from four main categories. Here is a simple explanation of each. **1. Qi Deficiency type**: The body's energy (Qi) is insufficient, slowing metabolism. Common in people who eat little yet gain weight, rarely exercise, get short of breath, or have a weak voice. This type often experiences yo-yo effects from extreme dieting that reduces muscle and vitality. **2. Spleen Deficiency + Phlegm-Fluid type**: When spleen function weakens, food is not properly digested and absorbed, leading to accumulation of unnecessary fluids and waste (Phlegm-Fluid). This feels like debris stuck in the body, causing puffiness, heaviness, and soft abdominal fat. Particularly common in those who enjoy flour-based foods, sweets, cold drinks, and feel drowsy after meals. **3. Blood Stasis type**: Poor blood circulation causes localized buildup of waste. Symptoms include abdominal pain or hard lumps when pressed, dark bluish veins under the tongue, severe menstrual cramps or headaches. Fat tends to be hard and stubborn, and treatment must include improving circulation (removing Blood Stasis). **4. Liver Depression + Stress type**: Stress causes liver function to stagnate (Liver Depression), disrupting appetite hormones. Seen in those who binge eat or crave late-night snacks, feel chest tightness or irritability. In TKM, the liver promotes the smooth flow of Qi; when this is blocked, weight gain mechanisms occur. This type requires lifestyle changes rather than just medication. Since multiple types often mix, diagnosis involves pulse reading (wrist), tongue examination, and abdominal palpation.
