Foreign bodies are objects that enter the body but are not naturally part of it. They can be anything from small items like coins or buttons to larger objects like toys or shards of glass. These objects can cause injury or infection, depending on their size, shape, and location within the body. When a foreign body is detected, medical professionals may need to remove it to prevent complications. This process can involve various methods, including endoscopy for smaller items or surgery for larger or more dangerous objects. Prompt treatment is essential to ensure the safety and health of the individual.
