How it works	Stellate Ganglion Block A clinician injects local anesthetic into the stellate ganglion, a nerve bundle in the neck that is part of the sympathetic nervous system. This may interrupt the temperature-regulation signals that trigger hot flashes.

Losing weight through behavioral changes in diet and exercise may reduce hot flashes for women who are overweight or obese.
