Digestive Health

  • GI Effects® Comprehensive Profile - 1 day

    The link between human health and the gut microbiome has been thoroughly researched and well-established over the years. An imbalance in this symbiotic relationship can often be the root cause of many common gastrointestinal complaints. This GI Effects panel provides practitioners with a comprehensive assessment of gut health through a combination of PCR, culture, and microscopic testing methods – ensuring any and all relevant organisms are identified. Our data-driven approach provides analysis based on hundreds of thousands of complete stool samples. Utilizing the latest technology and biomarkers, this profile can deliver valuable insight into digestive function, intestinal inflammation, and the intestinal microbiome.

Stephanie Strudley, CNS, is a functional medicine nutritionist and the founder of Upstream Wellness. She helps driven, health-conscious adults who've done "everything right" and still don't feel like themselves — connecting the dots between symptoms, labs, and lifestyle to uncover what's actually going on. Her approach is shaped by an unconventional path: a background in ecology and systems biology, and her own experience navigating serious, unresolved health challenges before finding root-cause care herself. She doesn't believe in one-size-fits-all protocols or quick fixes — she believes health is more like solving a puzzle than following a formula, and her role is to help clients ask better questions, interpret their own data, and build a plan that fits their unique biology and life.
