Why Does an Individual Get Hot Flashes After Eating?

Individuals may experience hot flashes after eating because the foods are disruptive to the body, causing an internal response where the blood vessels dilate while the nerve endings are stimulated simultaneously, as reported by Healthline Networks. Hot flashes are better described as periods of sudden warmth followed by periods of feeling chilled. Hot flashes are most intense at the facial regions, and can also result in profuse sweating, a rapid heartbeat and a flushed appearance.
