Problem
Digestive health issues affect up to 40% of adults and are often underdiagnosed, leading to frequent emergency visits, high medical costs, and reduced quality of life. Traditional GI care requires in‑person specialist visits, lengthy wait times, and fragmented coordination among providers.
Solution
Cylinder Health (VivanteHealth) delivers a virtual, clinician‑backed digestive health platform that provides personalized care for the full spectrum of GI symptoms and conditions. Members complete a free at‑home microbiome test and a symptom questionnaire, after which a coordinated team of board‑certified gastroenterologists, registered dietitians, and health coaches creates a customized care plan. The plan includes virtual appointments, diet and lifestyle recommendations, digital therapeutics, and ongoing symptom tracking, all accessible 24/7 through a secure web and mobile interface. Data are continuously collected and used to adjust treatment, reduce unnecessary in‑person visits, and improve outcomes while maintaining HIPAA‑level security (HITRUST and SOC 2 certified).
