The term bilateral in a medical context refers to something that affects both sides of the body or an organ. For example, if a patient has bilateral leg swelling, it means that both legs are swollen, rather than just one. This term is commonly used in various medical diagnoses and descriptions to indicate symmetry in symptoms or findings.
Understanding the term bilateral is important in diagnosing conditions that can affect both sides of the body, such as certain types of infections, injuries, or diseases like arthritis. By determining whether a condition is bilateral or unilateral (affecting one side), healthcare providers can better understand the underlying issues and decide on appropriate treatment plans.
