Brain-Liver Connection Found in Cancer-Related Weight Loss
Scientists have discovered a connection between the brain and the liver that can explain why cancer patients lose weight, a condition called cachexia.
Cancer causes inflammation that disrupts the vagus nerve, affecting how the liver works.
In a study, researchers blocked this nerve in mice, stopping the weight loss and improving their health.
This new approach is being tested in people and could become a treatment option to help cancer patients live longer and feel better.
Study links brain-liver communication disruption to weight loss in cancer patients.
Cachexia, characterized by weight and muscle loss, significantly impacts cancer patients.
Cancer-related inflammation disrupts vagus nerve signals, affecting liver function.
Blocking the vagus nerve in mice prevented cachexia and improved health.
Clinical trials with humans are underway using the new method.
