Postprandial Somnolence

Meaning

Postprandial somnolence, commonly known as the “food coma,” is the transient state of drowsiness or reduced alertness that occurs shortly after the consumption of a substantial meal. This physiological response is a normal, though sometimes disruptive, shift in arousal level that reflects the body’s metabolic prioritization toward digestion and nutrient absorption. While often benign, excessive or prolonged postprandial somnolence can indicate underlying issues with glucose regulation, insulin sensitivity, or autonomic nervous system balance. Clinical investigation of this phenomenon can reveal valuable insights into an individual’s metabolic flexibility.
