m3taversal a756745c18 vida: fix broken wiki links and add Vida to Active Agents table
- What: Converted 132 broken wiki links to plain text across 41 health domain files.
  Added Vida to the Active Agents table in CLAUDE.md.
- Why: Leo's PR #15 review required these two changes before merge.
- Details: Broken links were references to claims that don't yet exist (demand signals).
  Brackets removed so they read as plain text rather than broken links.

GLP-1 receptor agonists are the largest therapeutic category launch in pharmaceutical history but their chronic use model makes the net cost impact inflationary through 2035

The GLP-1 receptor agonist market reached $63-70 billion in 2025, with Eli Lilly's Mounjaro/Zepbound generating over $36 billion and Novo Nordisk's semaglutide products contributing another $48.9 billion. The market is projected to reach $250-315 billion by 2035 at 12.8-17.5% CAGR.

The oral GLP-1 breakthrough (FDA-approved oral Wegovy at $149/month vs. ~$1,350/month injectable) is a market-reshaping event that removes the injection barrier limiting adoption. Next-generation compounds (amycretin showing 22% weight loss without plateau, orforglipron as non-peptide small molecule) will further expand the addressable population. Approximately 11.8% of US adults reported GLP-1 use in 2025, more than double the 5.8% in February 2024. US obesity prevalence declined to 37% from 39.9% -- the first decline in recent years.

But the economics are structurally inflationary. Meta-analyses show patients regain an average of 9.69 kg after stopping, with all weight loss reversed after 1.7 years. Discontinuation rates are high: 46.5% of diabetic patients and 64.8% of non-diabetic patients quit within one year. This means GLP-1s for obesity are chronic, possibly lifelong medication. Medicare modeling projects drug costs rising from $11.3 billion in 2026 to $65.9 billion by 2035, with downstream savings (-$18.2 billion by year 10) never catching up to spending. Net spending increases across the entire 30-year horizon. Only 13 state Medicaid programs covered GLP-1s for obesity as of January 2026.

The competitive dynamics (Lilly vs. Novo vs. generics post-2031) will drive prices down, but volume growth more than offsets price compression. GLP-1s will be the single largest driver of pharmaceutical spending growth globally through 2035.
