Force-feeding is the practice of feeding a human or animal against its will. The term gavage (UKˈɡævɑːʒ,_ɡæˈvɑːʒ, USɡəˈvɑːʒ, ɡavaʒ) refers to supplying a substance by means of a small plastic feeding tube passed through the nose (nasogastric) or mouth (orogastric) into the stomach. Within some countries, in extreme cases, patients with anorexia nervosa who continually refuse significant dietary intake and weight restoration interventions may be involuntarily fed by force via nasogastric tube under restraint within specialist psychiatric hospitals. Such a practice may be highly distressing for both anorexia patients and healthcare staff. Some countries force-feed prisoners when they go on hunger strike. It has been prohibited since 1975 by the Declaration of Tokyo of the World Medical Association, provided that the prisoner is "capable of forming an unimpaired and rational judgment." The violation of this prohibition may be carried out in a manner that can be categorised as torture, as it may be extremely painful and result in severe bleeding and spreading of various diseases via the exchanged blood and mucus, especially when conducted with dirty equipment on a prison population. Large feeding pipes are traditionally used on hunger striking prisoners whereas thin pipes are preferred in hospitals. The Canadian government rejects the Declaration of Tokyo as made by the World Medical Association, and carries out the force-feeding of inmates against their will who reject any nourishment. Suffragettes who had been imprisoned while campaigning for votes for women went on hunger strike and were force fed. This lasted until the Prisoners Act of 1913, also known as the Cat and Mouse Act, whereby debilitated prisoners would be released, allowed to recover, and then re-arrested. Rubber tubes were inserted through the mouth (only occasionally through the nose) and into the stomach, and food poured down; the suffragettes were held down by force while the instruments were inserted into their bodies, an experience which has been likened to rape.
