Connotations
Neutral and technical in both varieties. In UK English, 'digestive' alone strongly connotes the biscuit (Digestive biscuit), creating a potential for minor puns in informal contexts.
Frequency
Similar frequency in educational and medical contexts. Slightly higher everyday familiarity in the UK due to the biscuit brand.
