メタボリックシンドローム：リスク因子群
メタボリックシンドロームは、一緒に発生する状態のグループで、心臓病、脳卒中、2型糖尿病のリスクを大幅に高めます。
メタボリックシンドロームとは？
5つのリスク因子のうち少なくとも3つを持っている場合にメタボリックシンドロームと診断されます：腹部肥満、高トリグリセリド、低HDLコレステロール、高血圧、空腹時血糖上昇。
5つの診断基準
1) 腹囲>85cm（男性）または>90cm（女性、日本基準）。2) トリグリセリド≥150 mg/dL。3) HDL<40 mg/dL（男性）または<50 mg/dL（女性）。4) 血圧≥130/85 mmHg。5) 空腹時血糖≥100 mg/dL。
健康リスク
メタボリックシンドロームは2型糖尿病と心血管疾患のリスクを大幅に高めます。
生活習慣による改善
メタボリックシンドロームは生活習慣の変更によって改善できることが多い：減量、定期的な運動、健康的な食事。
🌍 Regional Context
メタボリックシンドロームの有病率は肥満率の上昇とともに世界的に増加しています。
日本では成人の約20%がメタボリックシンドロームを持っています。「メタボ健診」として知られる特定健康診査が40歳以上に義務化されています。

🔬 Diagnostic Criteria
Healthcare providers use these thresholds to diagnose and classify metabolic syndrome:
| Metric | Threshold | Classification |
|---|---|---|
| Waist | >40" (men), >35" (women) | Criterion 1 |
| Triglycerides | ≥150 mg/dL | Criterion 2 |
| HDL | <40 (men), <50 (women) mg/dL | Criterion 3 |
| Blood Pressure | ≥130/85 mmHg | Criterion 4 |
| Fasting Glucose | ≥100 mg/dL | Criterion 5 |
Note: Diagnosis requires clinical evaluation. These criteria are for reference only.

🧬 Understanding Metabolic Syndrome
Medical LiteratureMetabolic syndrome represents the clustering of insulin resistance, central obesity, dyslipidemia, and hypertension. Visceral adipose tissue releases inflammatory adipokines (TNF-α, IL-6) and free fatty acids, driving insulin resistance. Insulin resistance increases hepatic VLDL production (elevated triglycerides) and reduces HDL. Compensatory hyperinsulinemia promotes sodium retention (hypertension) and vascular dysfunction. The syndrome amplifies cardiovascular risk beyond individual components—it represents a pro-inflammatory, pro-thrombotic state.

What metrics should I monitor for Metabolic Syndrome?
Key metrics include: Waist Circumference, Triglycerides, HDL Cholesterol, Blood Pressure, Fasting Glucose. Regular monitoring of these values can help track disease status and treatment response.
How is Metabolic Syndrome diagnosed?
Diagnosis typically involves: Waist circumference measurement, Fasting glucose or HbA1c, Lipid panel (triglycerides, HDL). Your healthcare provider will interpret these results in the context of your overall health.
Can Metabolic Syndrome be prevented?
Prevention strategies typically focus on lifestyle modifications and managing risk factors. Early detection through screening is also important.
