Supernatants of intestinal luminal contents from mice fed high‐fat diet impair intestinal motility by injuring enteric neurons and smooth muscle cells

Damage to enteric neurons and impaired gastrointestinal muscle contractions cause motility disorders in 70% of diabetic patients. It is thought that enteric neuropathy and dysmotility occur before overt diabetes, but triggers of these abnormalities are not fully known. We tested the hypothesis that intestinal contents of mice with and without high‐fat diet‐ (HFD‐) induced diabetic conditions contain molecules that impair gastrointestinal movements by damaging neurons and disrupting muscle contractions.
