What is the itis?

"Itis" is a colloquial term used to describe a feeling of tiredness or lethargy that often follows a meal, particularly one that is heavy or high in carbs. It is most commonly associated with foods like pasta, bread, and other starchy dishes.

The technical term for this phenomenon is postprandial somnolence, which refers to the drowsiness that can occur after eating. Itis is believed to be caused by the body redirecting blood flow to the digestive system in order to break down and absorb nutrients from the meal, which can make you feel sleepy.

There is some debate among experts about whether itis is a real physiological phenomenon or simply a result of overeating or consuming high-calorie meals. Some studies suggest that certain foods, such as those high in tryptophan or carbohydrates, can contribute to feelings of lethargy after eating.

Overall, itis is a common experience for many people, especially after large, carb-heavy meals, but its exact causes and mechanisms are still not fully understood.
