Okay, I need to create a professional Wikipedia-style document about "비만" (obesity) under the categories of Health, Medicine, and Disease Treatment. Let me start by understanding the user's requirements.

First, the structure: H1 for the title, an overview section, several sections with H2 and H3 headings, and maybe references or related documents. The content needs to be accurate, objective, detailed enough, easy to read, and use technical terms with explanations. Also, markdown formatting with proper hierarchy, lists, tables, code blocks if needed, and at least 800 characters.

Starting with the title: "비만" as H1. Then an overview section explaining what obesity is, its prevalence, causes, etc. Next sections could be classification (H2), causes (H2), health impacts (H2), treatment options (H2), prevention (H2). Under each of these, maybe H3 for sub-sections.

For the classification, I should mention BMI categories, types like visceral vs. subcutaneous fat. Causes would include diet, physical inactivity, genetics, hormonal factors. Health impacts could cover cardiovascular issues, diabetes, joint problems, mental health. Treatment options: lifestyle changes, medications, surgery. Prevention strategies: diet, exercise, education.

Need to make sure each section has enough detail but isn't too technical. Use terms like BMI with explanations. Maybe include a table for BMI categories. Also check that all information is accurate and up-to-date. References might be needed for statistics or studies mentioned.

Wait, the user said "필요시 참고 자료나 관련 문서 섹션" so maybe add a references section at the end. But since it's a wiki-style document, perhaps just mention sources in the text with citations? Or have a separate references section. The example given doesn't have one, but the instructions say to include if needed.

Also, check for markdown formatting: H1, H2, H3, lists (like bullet points), tables. Avoid code blocks unless there's technical content, which might not be here. Keep paragraphs concise.

Let me outline:

• Title: # 비만
• Overview: Brief intro on obesity as a global health issue.
• Classification: BMI categories, types of fat.
• Causes: Genetic, environmental, lifestyle factors.
• Health Impacts: Physical and mental health issues.
• Treatment Options: Lifestyle, medical, surgical.
• Prevention: Strategies to prevent obesity.

Each section with H2. Under each, maybe H3 for subtopics. For example, under treatment options, have H3 for lifestyle changes, medications, surgery.

Need to ensure that the content is over 800 characters. Let me check the sample response they provided earlier. The user's own example has around 1500 words, so I need to make sure mine meets the minimum.

Also, use technical terms but explain them. For instance, when mentioning BMI, define it. When talking about bariatric surgery, briefly explain what it is.

Avoid any markdown in the thinking process, but the final answer should have proper formatting. Make sure sections are well-structured with clear headings and subheadings. Use bullet points for lists where appropriate, like causes or treatment options.

Check that all information is accurate. For example, BMI categories: 18.5-24.9 is normal, 25-29.9 overweight, 30+ obese. Also mention different classifications like WHO vs. Asian criteria.

In the health impacts section, list specific diseases and conditions associated with obesity. In treatment, discuss diet, exercise, medications (like GLP-1 agonists), and surgeries (gastric bypass, sleeve gastrectomy).

Prevention strategies: public health initiatives, education, policy changes.

Make sure each paragraph isn't too long. Use short sentences and clear explanations. Avoid jargon unless necessary, and when used, explain it.

Now, start drafting the sections with these points in mind. Ensure that the document flows logically from introduction to classification, causes, impacts, treatment, prevention, and references if needed.
