| 【 要旨 】 | 日本ではBMI25以上を肥満と判定する．一方，肥満症は肥満と判定されたもので，健康障害があるか，内臓脂肪の過剰蓄積（内臓脂肪面積100cm2以上）であれば診断される．簡潔に言えば，治療すべき肥満が肥満症である．肥満症に合併する疾患の大部分は内臓脂肪蓄積が関与している．BMI35以上で，肥満肺胞低換気症候群や心不全を合併する肥満を高度肥満という． わずかな体重減少であっても，内臓脂肪は皮下脂肪に比し速やかに減少するので，合併する疾患の改善が期待できる．治療による体重減少の目標は現体重の3〜5％を3〜6カ月で減少させることである．この程度の体重減少により，肥満に起因する疾患の多くが改善されることが，特定健診・保健指導で実証されている． |

| [ Summary ] | Obesity is determined by body mass index (BMI) and defined as a BMI over 25. Obesity diseases are clinically defined based on the presence of complications related to obesity, or high risk obesity with an excess of visceral fat accumulation. In another words, individuals in this situation must reduce their weight for medical reasons. Visceral fat accumulation causes many complications. Even with slight weight reductions, visceral fat may be rapidly reduced, as compared to subcutaneous fat. Improvement in related complications can be expected with this loss. The goal of weight reduction is to lower body weight by 3 to 5 % in 3-6 months. By employing weight loss to this degree, it has been demonstrated by the National Health Guidance and Checkups that diseases caused by obesity are improved. Morbid obesity with BMI of 35 or greater or cases complicated by heart failure associated with obesity related alveolar hypoventilation are also discussed. |
