Using gut bacteria to treat obesity and severe weight loss in cancer

AI simplified

Abstract

The gut microbiota may serve as a novel therapeutic target for addressing metabolic disorders like obesity and cancer cachexia.

  • Obesity and cancer cachexia are linked by disrupted energy balance, inflammation, and neuroendocrine dysfunction.
  • Both conditions are associated with increased morbidity and mortality.
  • Gut microbial metabolites influence metabolic processes through specific signaling pathways.
  • Current treatments for obesity and cachexia often do not effectively target the underlying mechanisms.
  • Early interventions targeting the gut microbiome show promise but require further investigation to establish effective therapies.
