Trichophagia is a form of disordered eating in which persons with the disorder suck on, chew, swallow, or otherwise eat hair. The term is derived from ancient Greek θρίξ, ("hair") and φαγεῖν, ("to eat"). Tricho- refers only to the chewing of hair, whereas tricho- is ingestion of hair, but many texts refer to both habits as just trichophagia. It is considered a chronic psychiatric disorder of impulse control. Trichophagia belongs to a subset of pica disorders and is often associated with trichotillomania, the compulsive pulling out of ones own hair. People with trichotillomania often also have

Autocannibalism, also known as self-cannibalism and autosarcophagy, is the practice of eating parts of one's own body. Generally, only the consumption of flesh (including organ meat such as heart or liver) by an individual of the same species is considered cannibalism. In line with this usage, self-cannibalism means the consumption of flesh from one's own body. While some texts use this strict definition, others use the term autocannibalism in a wider sense that includes the consumption of hair or nails from one's own body.

Dermatophagia () or dermatodaxia () is a compulsion disorder of gnawing or biting one's own skin, most commonly at the fingers. This action can either be conscious or unconscious and it is considered to be a type of pica. Those affected with dermatophagia typically bite the skin around the nails, leading to bleeding and discoloration over time. Some people also bite on their skin on their finger knuckles which can lead to pain and bleeding just by moving their fingers.

Urophagia is the consumption of urine. Urine was consumed in several ancient cultures for various health, healing, and cosmetic purposes. People have been known to drink urine in extreme cases of water scarcity; however numerous sources, including the US Army Field Manual, advise against it. Urine may also be consumed as a sexual activity.

Pagophagia (from Greek: pagos, frost/ice, + phagō, to eat) is the compulsive consumption of ice or iced drinks. It is a form of the disorder known as pica, which in Latin refers to a magpie that eats everything indiscriminately. Pica's medical definition refers to the persistent consumption of nonnutritive substances, ice in this case, for over a period of at least one month. However, different studies have included alternative definitions for pagophagia, including "daily consumption of 2–11 full glasses of ice (480–2640 g)" or "the purposeful ingestion of at least one ordinary tray of ice dai
