Beyond gastric fundus resection, what autonomic neural reflex circuit is recruited post-VSG to increase energy expenditure and peripheral glucose disposal?

Question

Accepted Answer

Gastric mechanical stretch activates vagal afferents in the nodose ganglion, signalling to the NTS to drive efferent sympathetic stimulation of brown/beige fat thermogenesis.

Answer

Gastric sleeve creation eliminates luminal TSH breakdown, elevating circulating free T3 levels five-fold to stimulate skeletal muscle uncoupled respiration.

Answer

Hydrostatic pressure changes in the sleeve stimulate enteric motor neurons to release leptin directly into the portal vein to drive hepatic fatty acid oxidation.

Answer

Transection of the phrenic nerve during gastric stapling suppresses parasympathetic outflow, causing localized tissue hypoxia and white adipose browning.
