The word “sitophobia” owes its origin to two Greek roots words- “sito” meaning food and “phobia” which means fear. Therefore sitophobia translates to “a fear of food”. It is a common name for a group of complex diseases where a person reduces food consumption in a progressive manner and eventually stops eating completely or ends up eating meager quantities of food.
These people tend to avoid food during the normal meal hours. Owing to two main biological triggers namely- sleep and hunger, these people develop a strong repulsion towards food. Any disturbance in the homeostatic system and the circadian rhythm may aggravate the symptoms. In some cases, these people develop maladaptive eating patterns like avoiding food at the normal hours and eating is massive quantities at odd hours of the day.
