Force-feeding is the practice of feeding a human or other animal against their will. The term "gavage" (pronunciation: /ɡəˈvɑːʒ/) refers to the supplying of a nutritional substance by means of a small plastic feeding tube passed through the nose (nasogastric) or mouth (orogastric) into the stomach. In hospitals, some psychiatric patients can also be restrained so that sedatives can be injected into them; this happens if patients have been non-compliant with their instructions.
Soviet dissident Vladimir Bukovsky described how he was force-fed: "The feeding pipe was thick, thicker than my nostril, and would not go in. Blood came gushing out of my nose and tears down my cheeks, but they kept pushing until the cartilages cracked. I guess I would have screamed if I could, but I could not with the pipe in my throat. I could breathe neither in nor out at first; I wheezed like a drowning man — my lungs felt ready to burst. The doctor also seemed ready to burst into tears, but she kept shoving the pipe farther and farther down. Only when it reached my stomach could I resume breathing, carefully. Then she poured some slop through a funnel into the pipe that would choke me if it came back up. They held me down for another half-hour so that the liquid was absorbed by my stomach and could not be vomited back, and then began to pull the pipe out bit by bit."
"The unfortunate patients had their mouth clamped shut, had a rubber tube inserted into their mouth or nostril. They keep on pressing it down until it reaches your esophagus. A china funnel is attached to the other end of the tube and a cabbage-like mixture poured down the tube and through to the stomach. This was an unhealthy practice, as the food might have gone into their lungs and caused pneumonia."
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.
