BURLINGTON, Mass., June 01, 2026 (GLOBE NEWSWIRE) -- Fractyl Health, Inc. (Nasdaq: GUTS) (the Company or Fractyl), a clinical-stage metabolic therapeutics company focused on pioneering novel approaches to treat obesity and type 2 diabetes (T2D), today announced the appointment of Mike Zumdahl as Senior Vice President, Market Access and Commercial Strategy. Mr. Zumdahl served as Vice President of Global Health Economics, Market Access, and Government Affairs at Inari Medical, where he led the function through the company's growth and 2025 acquisition by Stryker.

“The post-GLP-1 weight maintenance problem represents the largest unmet need I have seen in metabolic disease in the last twenty years.
