GBH, or "Grievous Bodily Harm," is a legal term used in criminal law to describe a serious physical injury inflicted on a person. It is often categorized as a more severe form of assault, where the harm caused is significant enough to require medical attention. The term is commonly used in jurisdictions like the United Kingdom and can lead to severe penalties for the perpetrator. In legal contexts, GBH can be classified into two main types: "intentional" and "reckless." Intentional GBH occurs when someone deliberately causes serious injury, while reckless GBH involves causing harm without regard for the potential consequences. Both types are taken seriously by law enforcement and can result in lengthy prison sentences.
