Food aversions are intense negative reactions to specific foods or food groups. They can range from general (all foods) to specific (e.g., seafood), and can be temporary (e.g., pregnancy-related) or medical (e.g., associated with an underlying medical condition). Symptoms include nausea, vomiting, gagging, and refusal to eat. Management involves Cognitive Behavioral Therapy (CBT), gradual exposure therapy, medication, and practical strategies like avoiding triggers or eating small meals. Professional help is crucial for persistent aversions.
