queasiness

This term describes a visceral reaction that manifests as a physical instability in the stomach. It is most frequently used to describe the immediate biological precursor to vomiting, often triggered by motion, smell, or illness. The sensation is one of churning or instability rather than a sharp pain.

Beyond the physical, the word captures a specific type of psychological distress. When used in a moral or emotional sense, it refers to a feeling of internal misalignment or guilt. This suggests that the person finds a situation distasteful or ethically repulsive, mirroring the physical sensation of nausea in a mental state.
