Self-harm refers to an intentional act of self-poisoning or self-injury as an expression of emotional distress.
Mae hunan-niweidio yn cyfeirio at weithred fwriadol o hunan-wenwyno neu hunan-anafu fel ffordd o fynegi trallod emosiynol.
It has been reported that individuals feel that self-harm helps to relieve tension and makes them feel in control of their own lives.
It is almost impossible to say how many young people are self-harming. This is because very few teenagers tell anyone about it.
It is thought that around 13% of young people may try to hurt themselves on purpose at some point between the ages of 11 and 16, but the actual figure could be much higher.
Girls are thought to be more likely to self-harm than boys, yet boys are more likely to commit suicide. Children who have been abused have also been found more likely to self-harm.
Yn ôl y sôn, mae unigolion yn teimlo bod hunan-niweidio yn helpu i leddfu tensiwn ac yn gwneud iddyn nhw deimlo mewn rheolaeth o'u bywydau eu hunain.
Mae bron yn amhosibl dweud faint o bobl ifanc sy'n hunan-niweidio. Mae hyn oherwydd mai ychydig iawn o bobl yn eu harddegau sy'n sôn am hyn wrth neb arall.
Credir bod tua 13% o bobl ifanc yn ceisio niweidio eu hunain yn fwriadol ar ryw adeg rhwng 11 ac 16 oed, ond gallai'r gwir ffigur fod yn llawer mwy.
Credir bod merched yn fwy tebygol o hunan-niweidio na bechgyn, eto i gyd, mae bechgyn yn fwy tebygol o ladd eu hunain. Hefyd, gwelwyd bod plant sydd wedi cael eu camdrin yn fwy tebygol o hunan-niweidio.
