Yes. Avocados are processed by the body in much the same way as other high fat, high carbohydrate foods.
All food is processed in the gut through a huge number of digestive processes before being broken down to be absorbed across the wall of our intestines. Higher calorie foods take more time and energy for these processes to happen, which means they may slow intestinal motility (or move along at a slower rate). Knowing this, consuming too many highly caloric or greasy food sources can interfere with their processing through our system and cause diarrhea or cramping.
