"The itis" is a slang term used to describe the feeling of lethargy and drowsiness that some people experience after eating a large meal, particularly one that is high in carbohydrates and fats. This phenomenon is also known as postprandial somnolence, which is a medically recognized condition characterized by a general state of low energy related to activation of the parasympathetic nervous system in response to mass in the stomach. However, the term "the itis" has racist origins and is considered offensive by many people. It is derived from the word "niggeritis," which was used to reinforce the stereotype that black Americans were lazy. Therefore, it is recommended to use the technical term "postprandial somnolence" instead of "the itis" to avoid perpetuating harmful stereotypes.
