Heartburn is a painful, burning sensation in the chest or throat, typically caused by stomach acid backing up into the esophagus. This "deep" dive into the condition covers its physiological mechanisms, variations, and critical distinctions from more serious health issues. Physiological Mechanisms
: Brain imaging shows that perceived heartburn involves activated cortical regions in the sensory, motor, and prefrontal areas, with GERD patients showing more rapid and intense brain activity than healthy individuals.
